The digits in 1943 look like they took a hit. In my opinion it's a hit on the mintmark. If it were a Die Chip it would normally fill in the letter completely.
I used a 60x loupe from my friend ( this was taken with a 30x) , looks just like a partial grease filled die, no indents on the mint mark, it's flush across
If it was caused by a grease-filled die, the mintmark would disappear, but I can't state positively that it is PMD. I'd need a better close-up photo of the mintmark that isn't so blurry. Chris
Amazing how two photos of the same coin can look so different. On the first it looks like it took a hit and metal was shoved upwards. On second photo it looks like a partial die chip. Got me baffled.
The wonders of USB 'scopes. You can make a coin look all kinds of diferent ways depending on angle, distance, and lighting
