At first glance it looke like a dryer coin. Now I'm not sure. It looks more like a lamination, or plating bubble issue. Nothing pierced the copper plating, and the rim isn't banged up too much. The field seems affected as much as the letters, and bust.
The discoloration near the rim makes it look like heat damage to the copper plating. Plating Bubbles would be in random spots not all around both side of the fields. Acid Bath would melt the Zinc interior first No laminatons on a 2011 Copper Plated Cent Parking Lot Cent would be scratches
So you think heat damage? Maybe I'll put one in the microwave, er oven and see what happens. I don't see any scratches so it isn't parking lot/dryer damage. Thanks
