Hey folks! I found this 1976 bicentennial quarter in pocket change the other day, and I'm not sure what I have here. The quarter weighs about 5.7 grams, and the obverse seems a bit skewed - this is especially noticeable when you look at the ears.
I was hoping to get your opinions on whether minuscule S on the lower right side of Washington's head could be a misplaced mint mark, or do you think this is just a regular old Philadelphia minted coin that's silver-clad?
Thanks in advance!
