Hello all, I would appreciate your opinion on this coin as it has a very unusual mark at the top of the coin on the reverse and as you will see from the obverse there is no marks to say it's been in a clamp or anything similar, so what I'm asking is what do you think could have made this mark.
Looking at this I am positive that it was done at the time due to the fact that looking at it under high magnification, the edges are under or amalgamate with the wear of the coin and yes possible gear damage
