1968 Penny With Brockerage?

You can clearly see where the last A of CANADA (mirror image in the coin that was being pressed into this one) has been pushed down into the rim. Look just to the right and down of the designer's initials. I don't care what kind of crazy set-up could be between the dies - there is no collar die ever made, that would impart an incuse design on the rim.

Keep it, toss it away, do whatever you want with it - but it is only a conversation piece created by pressing one coin into another, nothing more. You don't need a vise to do this, a good whack with a heavy construction hammer could easily re-create this - I know, because in learning errors, I did all kinds of things to coins to understand the difference in post-mint damage and errors struck at the mint with hydraulic presses.

SPP were you always a Moderator? congrats if that is new...

for the coin, you may be right, I will try and recreate this in the week coming up...
