Can anyone please help me Define how this error is called? Besides the obvious damage made by people.
Well.. If it's damaged then obviously it doesn't have any kind of mint error. Don't assume that a strange looking coin is an error. That is circulation damage and alteration after it left the Mint Facility
YES! Excellent video! All those damaged coins look like the majority of PMD we see here on CT all the time! Thanks for sharing. I never saw it before.
With so much damage, what makes you think there is an error in there? (Frankly I had a hard enough time just determining it was the keelboat rev.)
