MrBreeze Valued Member United States 357 Posts	Posted 03/30/2022 11:57 am Wondering the cause of these holes / pock marks in the coin? Is it just zinc rot or environmental damage? They appear on both sides of the coin. Thanks! Report this Post to the Staff

coop Bedrock of the Community United States 62064 Posts	Posted 03/30/2022 12:02 pm Split plating exposes the zinc. Oxygen rots zinc. Pot holes are seen. Just a spender. acid will speed up the affect. Some day this copper wrapper, will look like a discarded Hershey's kiss wrapper. So spend it. Edited by coop 03/30/2022 12:52 pm Report this Post to the Staff

This layer helps prevent further deterioration of the zinc. The splitting of the copper plating on post 1981 Lincoln cents usually led to an exposed zinc core which in turn formed this protective layer. If that coin went into circulation, the normal use would cause that protective layer to be removed and a process of reformation would begin anew. The continuous handling of the coin would have a recurrence of these events, but with an increasing size of the affected area. Report this Post to the Staff
