Do you think its ruined ? I have a coin with a hole in it too . Its not ruined , I strongly Believe that.
Unless it is 1796 25cent - which went for $3k at auction... https://coins.ha.com/itm/early-quar...s-b-2-r3/a/1182-3394.s?hdnJumpToLot=1&x=0&y=0
Best case scenario, key fob item! How about that LordM, only he can make that hat look so cool! Good on you @lordmarcovan!
"Ruined"? Well, if it had been a valuable coin to begin with, its monetary value would have been very sharply decreased, to be sure. But since it wasn't a valuable coin to begin with, there's not much harm in the hole. It's just as fun as a keychain piece as it would have been as a common modern Mexican coin in your collection. In fact, a little more fun, I'd say, purely as a novelty or conversation piece.
