I know for one thing, a splitting headache? I know some may be deteriorating die. A crack from top of his head to an area down that the die “lifted” or “bubbled”. Comments appreciated! Thanks!
I see what you are referring to, and it does appear to be a more pronounced line in the hair, compared to other cents. Not sure if it is a crack or platting issue though.
I highlighted a few things that I see now. There is a dark line "black arrows" And what might be a retained interior die break " high lighted in blue" It could be the lighting but it looks raised.
I just checked a few 90's cents that I have. That heavy line in the hair is part of the design. But if you can see a raised line (crack) then that would be different. They call them cracked skulls, some or most would eventually turn into a retained IDB or IDB, blob in the hair forehead and behind the ear.
