I have an unusual 1963 Lincoln Cent with Canadian imprints. I've included multiple pictures and am interested to here your opinions on this coin.
It's been put in a vice with a Canadian 1c. coin & a block of wood either side & bashed with a hammer. Aidan.
US doesnt mint coins for Canada, or vice-versa, which would eliminate a 'mint error'. Its been hammered in one way or another, but not while held in a vice, since that doesnt make sense.
