What elements make up nickel coins?
In the U.S. the nickel component of coins is actually an alloy of 75% copper and 25% nickel so "nickels" are actually mostly copper! Dimes, quarters, and halves have a pure copper core with the same 75/25 alloy on the outside layers to give them a silvery appearance. Taken together that means the whole coin is around 85+ % copper. Other countries use different proportions of nickel and copper. For example, Canadian coins from the 1970s to the 1990s were pure nickel, while British 20p coins are about 80% copper.
