stoneman227 Pillar of the Community United States 2376 Posts	Posted 10/03/2019 5:13 pm The copper alloy of this cent is 95% copper and 5% tin and zinc. Since this planchet suffered from an improper alloy mix it looks to me that a nodule of zinc remained unmixed and was rolled into a line by the rolling mill and has oxidized Report this Post to the Staff
