I know this is PMD but I figured I'd share. This coin looks like the reverse design was heated up and twisted. Thought it was pretty cool!
I saw a dime like this once from a co-worker and offered to buy it from them and they said no. It looked like it was done with an old fashioned razor blade 1 cut a time. It looked so cool. I do not want people to cut up coins, but every now and then it is cool to see something not seen before.
You found the "Monticello falling into a wormhole" error! lol. Glad to see I'm not the only one that enjoys finding weird PMD's.
