Hey all! Been a while since I posted, but going through some of the backstock and found this odd little 1983. Never seen anything like it, doesn't match any listing I found. It's a raised area and seems like doubling but hoping someone more knowledgeable can chime in! Bonus crack on the back as is so common on these.
Have you tried to manipulate the raised area with a toothpick? If it moves at all, it is a plating bubble, if not, it could be a chip.
Nothing happened with poking and prodding, that's why I didn't think bubble in the first place. Seen plenty of those before
