Why copper or silver used in coins?
Pure copper, silver and gold has not been used to make general circulation coins for a long time, but for many years, the value of a coin was determined by the metal it was made from and its weight. British copper coins changed to bronze, which included a large percentage of copper, in 1860. British silver coins were gradually debased from 1919/1920 and changed to a copper nickel alloy from 1947. Copper was a relatively cheap and durable metal to make coins from once, but became much too expensive, even as part of a bronze alloy. In the early 1990's, all British bronze coins were subsequently made from copper plated steel. Silver was used to make coins of a higher value and the value of the coin was reflected in the diameter and weight of the coin, but silver also became too expensive.
Are copper coins pure copper?
