So I purchased this encased mirror button, which advertised a jewelry shop in Minneapolis. Luckily, because it was covered by some sort of plastic, it is still full red and beautiful! And I'm certain it hasn't been cleaned.
I cracked it out of the button, and I'm left with a bizarre oddity...
The strike is super, super razor sharp, the fields are super shiny and the rim seems squared. Normally, I'd be inclined to assume it to be a proof, but when looking at the reverse, I'm left COMPLETELY CONFUSED! Any ideas?
(Sorry for the poor pictures)
