Hello,

I'm new to the forum.
Does anyone know what damage/defect this might be on this 1951 1cent?
It looks lime some kind of impact crater with radial shock-lines emanating from it throughout the head. There's no bump or any other damage visible or felt on the opposite side.
Thanks for help.

Welcome to Coins and Canada

Got no answer for how that was done. It is damage of some sort as that
couldn’t happen when the coin was struck.

It is odd looking
