You know Sal, I think it was a palm sander. And it is a good look at the relief that each side was struck. Gotta admit that I have altered a few coins for reference.
I always get a good laugh out here. How could somebody do that and be so exact with the outline of the memorial. Nice picture of the sander thank you again kind people
A grinder of done sort. As in someone with too much time on their hands tried to make a genuine mint error. They failed miserably. Lol
