This is a close-up picture of a small black dot that is in the hair of a 1921 Morgan I own. I bought this coin several years ago, it had the spot when I got it & it has not changed size any. The coin is in an older PCGS slab. Any ideas of what the spot is? Would PCGS slab a coin in MS grade with a spot like this, or did it occur after slabbing?
