Not on this one. If you can see the metal displaced like in IGWT then it is a post-mint occurance.The circular pattern suggests, like furryfrog said, a coin roll crimper. the coin here looks like it had an especially rough crimper experience. Such a shame! Keep looking.
I think I need to "coin" the term "lincoln's halo" for these crimper PMD coins. Sure see a lot of them!
No the pic is fine. Look at both coins at the same time. The missing L in LIBERTY is just missing. That's from grease so thick that the Die can't stamp the L. On this Cent if you look at the number that's damaged you can see a line the that is curved like rim is. It goes right through the middle of the last digit. It's toned like the rest of the coin which shows it's age. Now look at the lower right hand side of the 3. That just caught a little of the damage. That curved line through the last digit is probably from a coin rolling machine like Evan showed.
Got it. Grease on the 1940, coin rolling machine on the 193(5). And I do see what you're talking about-- thanks.
