Im sure this is probably PMD its just odd where some of the marks stop. Rim is all flattened out and coin is thin as well but seams to weight the correct amount. Has anyone seen this before? Pics dont show it very well but there's a goldish tint to coin also.
Post-strike damage--possibly intentional, possibly 'dragged' across a concrete (or similar surface) a few times while lodged under a large, very heavy object. Certainly didn't leave the striking chamber in that condition.
Yes, I've seen similar damage on quarters, cents, nickels, etc.
