How Products are Made: How is a coin made?

History

Human civilizations have long used metals as a medium for exchange. In addition to their long-lasting properties, metals lend themselves easily to melting and casting. As early as 1000 B.C., the Chinese were using a type of metal token to represent payment. These artifacts have been labeled "spade" and "key" money because of their resemblance to a digging tool and to the modern-day Yale key. Both types bore denominations and were cast from molds. Although the ancient Egyptians did not mint coins, gold weights and rings were used to trade for products and services.

The first record of Western coins did not occur until 700 B.C., in western Asia Minor. Evidence of coins made from a naturally occurring alloy of gold and silver called electrum were found in the foundation of the temple to Artemis at Ephesus on the banks of the Aegean Sea. King Croesus of Lydia, who ruled from 560 to 546 B.C., has been credited with creating a bi-metallic system of pure gold and pure silver coins. These early coins typically carried imprints of animals, such as bulls, birds, insects, or mythical creatures. Engravings of vegetables were also popular. Imprints were stamped on one side of the coins with a tool bearing that particular design. Coin design was elevated to an art form during this period, and elaborately imprinted coins were afforded a high status. Many Greek cities vied for the distinction of having the most beautifully designed coins.

Alexander the Great built mints throughout his kingdom, from Macedonia to Babylon. He instituted uniform weights and types. It was during Alexander's reign that the coin portrait rose to popularity. Rulers, gods, and goddesses were the portraits of choice. By the fourth and fifth centuries A.D., engravers in Italy, and particularly in Sicily, were generally recognized as the experts in coin design. So revered was their skill that the engravers began signing their work.

Before the advent of the Industrial Age, the striking of coins was accomplished manually. A round blank of metal was placed over an anvil that had been fitted with an imprinted die. Another die was affixed to a pestle, which was then placed on top of the blank. The coin maker held the pestle in place with one hand and then brought a two-pound hammer down on top of the pestle. Remarkably, this resulted in seven tons of pressure, which forced impressions into both sides of the blank. The high relief typical of early Greek coins sometimes required two or three blows to achieve the desired effect. Heating the blank before striking often reduced the number of required strikes. This method allowed one coin to be struck every two seconds.

Raw Materials

Each country institutes strict guidelines for the composition of its currency. The outside vendors who provide the metal or "stock" to the mint must follow these guidelines to the letter. Originally, the U.S. penny (or cent) was composed of 95% copper and 5%zinc. In 1982, this composition was changed to a copper-plated zinc. A zinc alloy with traces of copper constitute the core of the coin, while the outer surface is electroplated with copper. Five-cent coins are composed of cupronickel, an alloy of 75 % copper and 25% nickel. Dimes, quarters, half dollars, and dollar coins are made from three layers of metal that have been bonded or "cladded" together. The outer layer is 75% copper and 25% nickel, while the core is pure copper.

In the factories of the outside vendors, the metal alloys are melted in furnaces and poured into rectangular molds. When the stock cools, it is rolled under pressure to the appropriate thicknesses. The rolling process causes the stock to harden excessively, requiring the application of a process called annealing. In this process, a series of heatings and coolings softens the stock and brings it to the consistency needed for shaping and stamping. The rectangular sheets of metal are cut into strips approximately 13 inches (33 cm) wide and 1,500 feet (457 m) long, and then rolled into coils. The mints purchase the coils according to their needs.

The Manufacturing
Process

Molding and engraving the master hub

  • When a new coin has been commissioned, sculptors employed by the mint develop a set of sketches. When one particular sketch has been approved and refined, the sculptor creates a clay model. The model can be anywhere from three to twelve times larger than the actual coin.
  • Plaster is poured over the clay model to create a negative, or reverse, plaster model. The words of the inscriptions are carved into the plaster in reverse. The sculptor repeats this process several times until the plaster model is perfect.
  • Next, a durable rubber mold is made by pouring epoxy into the plaster mold. The epoxy mold is mounted onto a transferengraver. At one end of the transfer-engraver, a stylus traces the epoxy mold. As the stylus moves, a ratio bar in the middle of the engraver reduces the design to the actual coin size. This reduced size is communicated to a carbide tool at the opposite end, which then cuts the design into a steel blank. The result is a positive replica called a "master hub." The sculptors examine the master hub and remove any imperfections.

Creating the working dies

  • Heat-treated metal is placed under a computerized lathe, where it is smoothed and polished into a precisely measured blank die. The master hub is pressed into the die. The result is called the "master die." The master die is used to create working hubs and working dies. The master hubs and dies are then placed in storage.

Punching out the blanks

  • The appropriate coil of metal is fed through a blanking press, which punches out round disks corresponding in size to the coin to be minted. The blanks are cut at a speed of 400 strokes per minute. The leftover scraps of metal are shredded and recycled for future use.

Annealing and pickling the blanks

  • The blanks are subjected to another annealing process and then placed in industrial washing machines and dryers. The lubricants used in these various processes cause the blanks to become stained and oxidized.
  • The blanks are next placed into revolving tubs or barrels filled with an acidic pickling agent. As the blanks are tossed together in the tubs, they become burnished.

Sorting and weeding the blanks

  • The blanks are sifted through a "riddler," a metal sheet fitted with holes that match the exact size of the particular coin to be minted. In this manner, misshapen and odd-sized blanks are weeded out.

Striking the coins

  • The perfect blanks are carried by conveyer belt to the coining press, where they are stamped with designs and inscriptions. A steel collar is inserted into the press around one of the dies. The die for the reverse side is loaded into the upper arm of the press. Hundreds of tons of air pressure push the blank into the collar. At the same time, the overhead die is forced down into the collar and onto the blank. The impact causes the impressions to form on both sides of the blank. The press releases the newly minted coin, and it moves along a conveyer belt to the inspection line.

    In some instances, the collar has grooves to make the ridged edges on the coin. Otherwise, the grooves are made after the striking process, on a tool called an upsetting mill. The size of the press varies from single capacity to ones that stamp four coins simultaneously. Single-striking presses generally stamp 400 coins per minute, with pressure loads up to 180 tons. Multiple presses can crank out 120 coins per minute under 250 tons of pressure.

Inspecting and sorting

  • The press operator spot-checks each batch of new coins with a magnifying glass. The coins move through another riddler that sorts out blanks that have become misshapen or dented during the striking process.

Counting and bagging

  • An automatic counting machine spits I out a predetermined amount of coins and drops them into large canvas bags. The bags are sewn shut, loaded onto pallets, and then moved by forklift trucks to storage vaults.

Quality Control

Inspections are carried out at many points throughout the engraving and manufacturing process. Alloys are analyzed using xray fluorescent spectrometers or chemical processes. The surface condition of the blanks is checked frequently for maximum center line average. The diameters of the blanks are measured with gauges such as micrometers. Weights are controlled by weighing a specific number of coins against a standard weight plus a pre-determined allowance.

The Future

In the mid-1990s, the U.S. made preparations to join other industrialized countries in the use of a dollar coin instead of a paper bill. Although backers point to the savings that the switch would bring, and environmentalists extol the virtues of phasing out the dollar bill, traditionalists see the dollar bill as a well-entrenched symbol of the United States. Unions and trade associations representing the paper industry also voiced opposition to the new coin.

Elimination of the penny has also gained support in recent years. Ironically, the American public's view of the penny as worthless has caused millions of people to stockpile them in jars and boxes at home, to be traded in for larger denominations at a later date. This has led to a shortage of pennies in the commercial arena. Decisions about eliminating coins are intensely political, attesting to the continuing symbolic power of the metallic coin.

The belief reported most regularly about coins is that a holed or bent coin is lucky. The coin with a hole is mentioned from the 1830s to the 1950s. The Poole and Dorsetshire Herald of 11 February 1847 details how a local shopkeeper had kept all holed coins she had received over the counter, in the belief that they were special and should only be used for holy purposes (reprinted in Morsley, 1979: 305). Edward Lovett, collector of First World War beliefs, described meeting a soldier who showed him an old farthing with a hole in it, which he carried as his mascot. Also lucky was a bent coin, such as the ‘crooked sixpence’ of the nursery rhyme, but this is recorded from a much earlier date, being mentioned (as ‘bowed silver’ or ‘bowed groat’, etc.) by playwrights from the 16th century onwards (see Lean), often in the context of a gift, as for example in the description by John Foxe of the martyrdom of Alice Benden at Canterbury, in 1557: ‘A shilling also of Philip and Mary she took forth, which her father had bowed and sent her when she was first sent to prison’, and similar gifts were reported into the late 19th century (N&Q 1s: 10 (1854), 505). Finucane (1977: 94-5) reports numerous examples of coin-bending in medieval times, in confirmation of a vow, when in danger, as part of a cure, or for general good luck. In each case the bent coin was offered to a saint.

Most other coin beliefs have been shortlived or at least have escaped being recorded more than once or twice, except in the case of fishermen who used to cut a slit in one of the cork floats of their nets, reputedly to let Neptune know they were willing to buy the fish they caught, and the widespread practice of placing a coin under the mast of any new boat—‘for luck’.

(coinage) [Ar]

A metal token, usually a disc, with specific weight and value, usually stamped with designs and inscriptions. The earliest known coins in the world were minted by the kingdom of Lydians in the Near East in the 7th century bc. The coins, made of electrum, were simply pieces of metal of standardized weight stamped with designs and later inscriptions to identify the issuing authority. It is not exactly certain how they were initially used, but it was probably for high-level ceremonial exchange rather than everyday trade. After Cyrus the Great gained control of Lydia in the 6th century bc the Achaemenids Persians adopted a gold coinage that typically had a portrait of their king on one side and a punch mark on the other. The Greek cities of Asia Minor also copied the Lydian idea for coins in the 7th century, after which the idea spread widely throughout Greece. The first Roman coins were struck in the early 3rd century bc, initially in precious metals but by the later 3rd century in bronze as the as and the denarius in silver. The 4th-century bc staters of Phillip II and Alexander III of Macedon provided the prototypes for coins in Europe which developed their own sequence based on the use of Celtic art and local designs.

In the Far East, coinage developed in India in the 5th century bc through contacts with Persian/Achaemenid coinage by Mauryans and Kushans. In China shells and other small items were used as money down to the Zhou Dynasty and beyond, but from the 3rd century bc onwards round coins with a central square hole began to circulate.

 
piece of metal, usually a disk of gold, silver, nickel, bronze, copper, aluminum, or a combination of such metals, stamped by authority of a government as a guarantee of its real or exchange value and used as money. Coinage was probably invented independently in Lydia or in the Aegean Islands and in China before 700 B.C. The earliest known example is an electrum coin (c.700 B.C.) of Lydia. The first U.S. mint was established in 1792. Mottoes used on many U.S. coins are “E Pluribus Unum” (1795) and “In God We Trust” (1864). Early coins were die-struck by hand and showed many individual variations. Standardized coins date from the use of a mill and screw machine (invented c.1561). Coins are usually stamped from rolled metal blanks, then milled. The final product bears a design impressed upon it between the upper and lower dies of a coining press. Milled or lettered edges have been used since the 17th cent. to discourage the removal of slivers of metal, especially from gold or silver coins. No gold coins have circulated in the United States since 1934, when the domestic gold standard was abandoned. Until 1965, silver was used in the minting of dimes and quarters, but by the 1980s silver had disappeared from American coinage altogether. In the mid-1990s, the European Union developed a common currency for its members. The new currency, called the euro, was inaugurated in 1999; coins and notes went into circulation in 2002, replacing the currencies of most EU members (see European Monetary System). Canada introduced the first colored coin for circulation in 2004; it was a quarter featuring a poppy. See also numismatics.

A coin is usually a piece of hard material, usually metal or a metallic material, usually in the shape of a disc, and most often issued by a government. Coins are used as a form of money in transactions of various kinds, from the everyday circulation of the United States quarter, to the storage of vast amounts of bullion. In the present day, coins and banknotes make up the cash forms of all modern money systems. Coins made for circulation (general monetized use) are usually used for lower-valued units, and banknotes for the higher values; also, in most money systems, the highest value coin is worth less than the lowest-value note. The face value of circulation coins is usually higher than the gross value of the metal used in making them.

Exceptions to these rules occur for non-monetized "bullion coins" made of silver or gold (and, rarely, other metals, such as platinum or palladium), intended for collectors or investors in precious metals. For examples of modern gold collector/investor coins, the United States mints the American Gold Eagle, Canada mints the Canadian Gold Maple Leaf, and South Africa mints the Krugerrand. The U.S. Eagle coin has a "face value" of ten U.S. dollars (and theoretically could be used to pay for goods or services worth ten dollars), and the Double Eagle has a "face value" of twenty U.S. dollars, but these denominations are historical references to pre-depression times when this was the case; of course, these face values are no longer relevant, since the market value of the coin, and the gold in it, is many times the face amount. The Canadian Gold Maple Leaf also has nominal face value, but the Krugerrand does not.

Historically, a great number of coinage metals (including alloys) and other materials have been used practically, impractically (i.e., rarely), artistically, and experimentally in the production of coins for circulation, collection, and metal investment, where bullion coins often serve as more convenient stores of assured metal quantity and purity than other bullion.

The value of a coin

In terms of its value as a collector's item, a coin is generally made more or less valuable by its condition, specific historical significance, rarity, quality/beauty of the design and general popularity with collectors. If a coin is deeply lacking in any of these, it is unlikely to be worth much. Bullion coins are also valued based on these factors, but are largely valued based on the value of the gold or silver in them.

Most coins nowadays are made of a base metal, and their value comes from their status as fiat money. This means that the value of the coin is decreed by government fiat (law), and thus is determined by the free market only as national currencies are subjected to arbitrage in international trade. This causes such coins to be monetary tokens in the same sense that paper currency is, when the paper currency is not backed directly by metal, but rather by a government guarantee of international exchange of goods or services. Some have suggested that such coins not be considered to be "true coins" (see below). However, because fiat money is backed by government guarantee of a certain amount of goods and services, where the value of this is in turn determined by free market currency arbitrage, similar to the case for the international arbitrage which determines the value of metals which back commodity money, in practice there is very little practical economic difference between the two types of money (types of currencies).

Sometimes, coins are minted that have fiat values lower than the value of their component metals, but this is never done intentionally and initially, and happens in due course later in the history of coin production due to inflation, as market values for the metal overtake the fiat declared face value of the coin. Examples of this phenomenon include the pre-1964 US dime, quarter, half dollar, and dollar, US nickel, and pre-1982 US penny. As a result of the increase in the value of copper, the United States greatly reduced the amount of copper in each penny. Since mid-1982, United States pennies are made of 97.5% zinc coated with 2.5% copper. Extreme difference between fiat values and metal values of coins causes coins to be removed from the market by illicit smelters interested in the value of their metal content. In fact, the United States Mint, in anticipation of this practice, implemented new interim rules on December 14, 2006, subject to public comment for 30 days, which criminalize the melting and export of pennies and nickels.[1] Violators can be punished with a fine of up to $10,000 and/or imprisoned for a maximum of five years.

To distinguish between these two types of coins, as well as from other forms of tokens which have been used as money, some monetary scholars have attempted to define by three criteria that an object must meet to be a "true coin". [citation needed] These criteria are:

  1. It must be made of a valuable material, and trade for close to the market value of that material.
  2. It must be of a standardized weight and purity.
  3. It must be marked to identify the authority that guarantees the content.

It is believed by some scholars that the first coins (following the criteria above) were manufactured in Lydia, but apart from one example with the legend "I am the badge of Phales", these pieces have no writing on them, merely symbolic animals. Therefore it is pure guesswork to date the coins, and numismatists' only clue is that some were found buried under a temple from the early 6th Century BCE. Many great classical numismatists have debated whether these coins may have been struck (manufactured) under the authority of private individuals, although, as the coins get more common, it is certainly thought that some were made under King Croseus.


The first European coin to use Arabic numerals to date the year minted was the Swiss 1424 St. Gallen silver Plappart.

First coins

The question of the world's first coin has been, and still is debated. While it is believed by many that the Lydian Lion trite is the world's oldest coin, some argue that India's karshapanam is the world's first coin.[1][2] On the other hand, some argue that Indian coins were developed from Western prototypes, which the Indians came in contact with through Babylonian traders.[3]

The first coins were minted around the 6th century BC by the Mahajanapadas of the Indo-Gangetic Plain. The coins of this period were punch marked coins called Puranas, Karshapanas or Pana. The Mahajanapadas that minted their own coins included Gandhara[4], Kuntala[5], Kuru[6], Panchala[7], Shakya[8] , Surasena[9] and Surashtra[10].

Coin debasement

Main article: Debasement

Throughout history, governments have been known to create more coinage than their supply of precious metals would allow. By replacing some fraction of a coin's precious metal content with a base metal (often copper or nickel), the intrinsic value of each individual coin was reduced (thereby "debasing" their money), allowing the coining authority to produce more coins than would otherwise be possible. Debasement sometimes occurs in order to make the coin harder and therefore less likely to be worn down as quickly. Debasement of money almost always leads to price inflation unless price controls are also instituted by the governing authority, in which case a black market will often arise.

The United States is unusual in that it has only slightly modified its coinage system (except for the images and symbols on the coins, which have changed a number of times) to accommodate two centuries of inflation. The one-cent coin has changed little since 1864 (though its composition was changed in 1982 to remove virtually all copper from the coin) and still remains in circulation, despite a greatly reduced purchasing power. On the other end of the spectrum, the largest coin in common circulation is 25 cents, a low value for the largest denomination coin compared to other countries. Recent increases in the prices of copper, nickel, and zinc, mean that both the US one- and five-cent coins are now worth more for their raw metal content than their face (fiat) value. In particular, copper one-cent pieces (those dated prior to 1982 and some 1982-dated coins) now contain about two cents' worth of copper. Some denominations of circulating coins that were formerly minted in the United States are no longer made. These include coins with a face value of half a cent, two cents, three cents, twenty cents, two dollars and fifty cents, three dollars, five dollars, ten dollars, and twenty dollars. In addition, cents were originally slightly larger than the modern quarter and weighed nearly half an ounce, while five cent coins were smaller than a dime and made of a silver alloy. Dollars were also much larger and weighed approximately an ounce. Half dollar and one dollar coins are still produced but rarely used. The U.S. also has bullion and commemorative coins with the following denominations: 50¢, $1, $5, $10, $25, $50, and $100.

The milled, or reeded, edges still found on many coins (always those that were once made of gold or silver, even if not so now) were originally designed to show that none of the valuable metal had been shaved off the coin. Prior to the use of milled edges, circulating coins commonly suffered from "shaving", by which unscrupulous persons would shave a small amount of precious metal from the edge. Unmilled British sterling silver coins were known to be shaved to almost half of their minted weight. This form of debasement in Tudor England led to the formulation of Gresham's Law. The monarch would have to periodically recall circulating coins, paying only bullion value of the silver, and re-mint them.

Traditionally, the side of a coin carrying a bust of a monarch or other authority, or a national emblem, is called the obverse, or colloquially, heads. The other side is called the reverse, or colloquially, tails. However, the rule is violated in some cases. [2] Another rule is that the side carrying the year of minting is the obverse, although some Chinese coins, most Canadian coins, the British 20p coin, and all Japanese coins, are an exception.

The orientation of the obverse with respect to the reverse differs between countries. Some coins have coin orientation, where the coin must be flipped vertically to see the other side; other coins, such as British coins, have medallic orientation, where the coin must be flipped horizontally to see the other side.

The exergue is the space on a coin beneath the main design, often used to show the coin's date, although it is sometimes left blank or containing a mintmark, privy mark, or some other decorative or informative design feature. Many coins do not have an exergue at all, and they are most common on coins with little or no legends such as the Victorian bun penny.

Coins that are not round (British 50 pence for example) usually have an odd number of sides, with the edges rounded off. This is so that the coin has a constant diameter, and will therefore be recognised by vending machines whichever way it is inserted. If a coin had an even number of sides this would not be possible. Some such older designs remain, however, such as the 12-sided Australian 50 cent coin.

Coins are popularly used as a sort of two-sided die; in order to choose between two options with a random possibility, one choice will be labeled "heads" and the other "tails," and a coin will be flipped or "tossed" to see whether the heads or tails side comes up on top. See Bernoulli trial; a fair coin is defined to have the probability of heads (in the parlance of Bernoulli trials, a "success") of exactly 0.5. A widely publicized example of an asymmetrical coin is the Belgian one euro coin [3]. See also coin flipping.

Coins are sometimes falsified to make one side weigh more. Such a coin is said to be "weighted."

Some coins, called bracteates, are so thin they can only be struck on one side.

Bi-metallic coins are sometimes used for higher values and for commemorative purposes. In the 1990s, France used a tri-metallic coin. Common circulating examples include the €1, €2, British £2 and Canadian $2.

Guitar-shaped coins were once issued in Somalia, Poland once issued a fan-shaped 10 złoty coin, but perhaps the oddest coin ever was the 2002 $10 coin from Nauru, a Europe-shaped coin.[4]

The Royal Canadian Mint is now able to produce holographic-effect gold and silver coinage.
