Guessing this is PMD obverse left side...Hopefully you can see it ok. I have seen a lot of 80's with this damage and I bet you guys have too so not 100% sure this is PMD but I will tell you this one is deeper than any one I have ever seen...What do you guys think?
Not PMD but from a worn die. Notice also, the polishing marks. They were trying to save this die too long.
