Here is an interesting 2016-P Shawnee, Illinois 25C I found in change filled with tons, and I mean TONS of planchet damage. Just thought it was neat.
Yes to Die Deterioration. Not a Planchet error but a worn Die issue. I would not say tons of planchet errors.. that would be pretty heavy
Yes my bad, I mix die deterioration and planchet damage up. Planchet damage is more on the obverse, die deterioration on reverse.
