Die break? Domestic die over Foreign planchet? Any input would be greatly appreciated. Im just an amatuer collector I look for errors and I'm collecting wheat pennies for my son. My name is Gina, nice to meet you all! Thanks in advance.
Looks like a Japanese Kabuto mask.. Not struck on foreign planchet I looks like PMD - Post Mint Damage
Welcome Gina. That is an interesting coin and while I don't have an answer for you, I'm sure someone here will. Good luck on collecting.
Yes. PMD = Post Mint Damage, aka someone damaged it after it left the mint by an unlimited various destructive methods. In this case you can see the rims are squashed like using a wrench/hand type press. Then some metal stamp - bottom side probably convex to push material to the concave image stamp. They probably tried it on the other area too close to the pivot point and only crimped the coin rim. Then moved the coin further out and tried again, more successfully. That would be my guess.
Post mint damage. Someone used a punch to move the metal and create that face. Google 'Pop out coin' and you will see a lot. Some may have value, don't know about that.
here's a good thread about them https://www.cointalk.com/threads/repousee-coins-aka-push-outs-or-pop-outs.225062/
I know finding a rare valuable coin has about the same probability of winning 2 consecutive lotto jackpots, but its fun to look!
Question, did the person with a stamp have a stamp on both sides ? What kind of stamp was used? How *exactly* did they stamp it?
The edges of the coin are still in great condition, not flattened anywhere, just has a little wave in it.
