No country has ever issued pure* silver coins for circulation. Pure silver is soft, and coins made out of it would wear out very quickly. Silver is almost always alloyed with copper or some other so-called base metal to make it harder and more resistant to wear.
The amount of pure silver in the alloy varies depending on the issuing country's coinage policies and other factors. For example:
Today many countries mint bullion coins out of pure silver for sale to collectors and investors. They're sold by weight at a price that varies almost daily due to changes in the precious-metals market. These special coins aren't intended to circulate.
(*) For chemical reasons it's almost impossible to produce 100% pure silver. In practice the term "pure silver" refers to silver that's 99.9% pure with the remainder being trace elements.
The earliest coins were made in 700-600 BC and were made out of Electrum which is a naturally occurring mix of both gold and silver. The first pure gold coins were made in about 560 BC.
silver coins
Silver and gold were the materials of the first coins produced - they have been used as such for several thousand years.
2050 BC
Coins date back to Ancient history to today. The earliest coins date on or before 700 BC in Aegina Island or Ephesus, Lydia. The first coins were made of a mixture of gold and silver that was alloyed with silver and copper. The Persian daric was the first gold coin, but some of the most famous were the Roman and Greek coins.
Nothing is 100% PURE silver but like most silver coins it is 99.999% silver
No. The US has never made a coin with pure silver. The closest to pure silver would be American silver Eagles. These coins are silver bullion coins. They are made of 99.93% silver and .07% copper.
There are 4 Isle of Man 1976 Commemorative Crown coins. Two are silver, two are copper-nickel. The silver coins coins are 0.9250 silver, as close as you are likely to get to pure silver.
"Pure" silver coins were never minted in Britain. The closest to pure silver used in coins is sterling silver which is 92.5% silver usually alloyed with copper. Sterling silver coins were last issued for general circulation in 1919 and 1920, beyond 1919/1920 the coins were debased to 50% silver. The Royal Mint still produces Proof and bullion coins (not for general circulation) which are made from sterling silver, but this is reflected in the price you pay for them.
All silver US coins dated 1964 and before are 90% silver none are pure silver.
The Australian Kookaburra series of Proof and Specimen coins first issued by the Perth Mint in 1990, at 99.99% silver, are as close to pure silver as you are ever likely to get in a coin.
Copper has almost always been used in silver coins, because pure silver wears out faster.
No, nor are ANY U.S. silver coins pure silver. It's 90% silver with 10% copper.
Coins are not usually silver these days. Since the 1960s they have been made of copper and nickel. Silver coins from before 1965 in the US were 90% silver. Foreign countries have used anything from 40% to 92.5% silver in their coins, but to my knowledge, no one has used pure (100%) silver in currency.
Silver dollar coins (1794-1935) were never made of pure silver. It's too soft and the coins would wear out very quickly. They (and most other silver US coins) were made of an alloy of 90% silver and 10% copper. Circulating US dollar coins were made of copper-nickel from 1971 to 1999. The composition was changed to gold-toned brass in 2000. Modern "eagle" coins with an artificial $1 denomination are made of 99.9% pure silver, but these coins aren't intended for spending.
First, U.S. coins were never pure silver. The silver American Eagles come the closest at 99.9% pure. As for the circulating coins, they were 90% silver and were last dated 1964 even though mintage of the 1964 dates continued part way into 1965 to counteract hoarding.
American circulation coins were never made of pure silver. They contained at least 10% copper for hardness. 1971 dollar coins for circulation contained NO silver - they were made of copper and nickel. Collectors' coins were struck in 40% silver.
