Most of the time the nickel has a silvery appearance as the coin's color is dominated by the nickel metal. The nickel is very hard and does not corrode. In the presence of a strong oxidizer (acid, base etc) the nickel will take on a copper color. These coppery "nickels" are fairly common. Errors do exist where a cent blank was struck with ...
