Nickel has been a minor component of British Coins for many years, but as the price of silver rose, notably around 1919, the silver content dropped from 92.5% to 50% and the nickel and copper content increased accordingly. After WW2, silver became cost prohibitive for British coinage due to the need to repay War loans to the USA. From 1947 onwards, silver was completely dropped from all general circulation British coins and replaced with coins of cupro-nickel (75% copper and 25% nickel most commonly).
there is a website called Numista
To find out which years coins containing nickel were made, you can consult numismatic resources or databases that list coin compositions by year and denomination. Websites like the U.S. Mint or numismatic catalogs can provide detailed information on the metal content of coins, including those containing nickel. Additionally, coin collecting forums and books on coin identification may also have relevant information on specific years and types of nickel-containing coins.
How could you find out which years coins containing nickel were made in?
British decimal 1 and 2 Pence coins have never contained nickel. From their introduction in 1971, the 1 and 2 Pence coins were made from bronze, consisting of 97% copper, 2.5% zinc and 0.5% tin. From 1992 onwards, they have been made from copper plated steel. A 25% nickel content is used in the British 5, 10, 20 and 50 Pence coins and gives the coins their silvery appearance. The Five Pound coin and the centre of the Two Pound coin also contains 25% nickel. The One Pound coin has a 5.5% nickel content.
People in the US have been using nickel coins since 1866 (still in use today).
Pure copper has not been used to make British coins for about 150 years. From 1860, British "copper" coins were made from bronze which consisted mostly of copper varying from 95 to 97% copper. From 1992, British "copper" coins were made from copper plated steel. Ironically, copper is used to make modern "silver" coins (cupro-nickel) consisting usually of 75% copper and 25% nickel.
Since 1992, copper is only used in British "silver" coins in an alloy with nickel, most commonly 75% copper and 25 % nickel giving the coins a silver appearance. The combination of copper and nickel gives a hard wearing and durable coin that is resistant to corrosion.
No British coin is magnetic. Coins made from steel can be attracted to a magnet. From 1968 to 2011, the British 10 Pence coin was made from a copper-nickel alloy and therefore have no magnetic properties, copper and nickel both being non-ferrous metals. From late 2011, the British 10 Pence coin is made from nickel plated steel which has some magnetic properties similar to the 1 Penny and 2 Pence coins issued from 1992. The move towards coins made from steel is an effort by many countries to reduce the cost of manufacturing coins. Also, the coins are much more durable, even if the plating is not, and may extend the life expectancy of coins well beyond 50 years.
The Royal Mint has not produced a purely copper coin since 1860 when they changed to bronze for making "copper" coins. The bronze consisted of 97% copper, 2.5% zinc and 0.5% tin. All British "copper" coins are now made from copper plated steel. The Royal Mint does not produce any purely nickel coins either, but coins made from an alloy of 75% copper and 25% nickel. Of the two, the copper/nickel coins would last a little longer. The Royal Mint expects to get 40 to 50 years use out of its coins before they recycle them.
Zero. Due to the steep rise in the price of silver in 1919/20, the issue of standard .925 silver coins was discontinued and coins of .500 silver were minted. In 1947, silver was needed to repay the bullion lent by the USA during the war years, so silver coins were replaced with coins of the same weight and type made of cupro-nickel.
1919 and 1920 were the two years when the British silver coinage was debased from 0.9250 to 0.5000 silver. Which year the change was made depends on the denomination of the coin. Prior to 1919/1920, all British "silver" coins had a 92.5% silver content. From 1919/1920 to 1946, all British "silver" coins had a 50% silver content. From 1947 to present, all circulating British "silver" coins had a 0% silver content.
First isolated in 1751 by Cronstedt, an event commemorated by Canada in 1951 with a special 5c piece. However, the element is present in alloy form in early Bactrian coins dating from about 200 BC. Usually used in an alloy with copper (see cupro-nickel) or iron (see stainless steel), although the pure metal has been (and is) used a great deal, notably for the coins of Switzerland and Canada. It was first used in this form by Switzerland in 1881. The pure metal is magnetic, and is noticeably yellower than some of the silvery metals such as chromium and aluminium. In 1965 the United States produced pattern coins in a 95% nickel 5% silicon alloy, but it appears that all specimens were melted down. There is some concern that a number of people are allergic to nickel, thus the avoidance of this element in alloys used for the new euro coins.
