Is that the zinc core maybe trying to rot from inside? Report this Post to the Staff

Dearborn Moderator United States 95787 Posts	Posted 04/30/2022 8:14 pm Strange type of rot from the zinc core, but I'll agree that it is.. Collecting since 1972.

silviosi Pillar of the Community Canada 6244 Posts	Posted 04/30/2022 11:23 pm If we look more attentively, we can see this coin it is a plating default. the sides of the coins has more electro so plated well. The meddle which has more resistance was very week plated due to the fact miss enough intensity of the current. Is my opinion. Damage it is not in Mint state. Report this Post to the Staff
coop Bedrock of the Community United States 62064 Posts	Posted 05/01/2022 12:33 pm It could be movement of the plating that caused a riff during the strike, not starting to rot. It is not a plus for the coin. More of a problem coin issue. Note the rough field bumps also seen on the raised devices. That was an issue of plating over zinc dust. This was normal for the time. But also a distraction for for the coin. (again not a plus for the coin) Report this Post to the Staff
