just carl Bedrock of the Community United States 20753 Posts	Posted 10/07/2018 12:04 pm Although it is called a Nickel, it is .75% Copper and only .25% Nickel. It is more of a Copper with Oxygen reaction your seeing. Note how on pennies (Cents) they turn a dark brown as they get Oxygenated. Might be why the Mint puts 5 Cents on the back rather than saying a Nickel. Edited by just carl 10/07/2018 12:06 pm Report this Post to the Staff
