One of the best indicators of this coin having post mint damage is the lack of rims. Hard to tell how exactly this damage occurred as it would only be a guess, but in the end, damage is just damage. Coins led a rough life once minted.
Thank you for the advice about the pics. First time posting. Will do that for the next one. Also appreciate the info on the coin it was too odd not to look into. Definitely gonna keep around cause it is pretty cool looking.
