It's possible that your coin could have the same type of reverse
and also the broken serif on the obverse but it cannot have the
accented hair. The AH was only on earlier 1964 proofs. Jackie Kennedy
did not like the look of her husbands hair on the new proof when it CAM
e out so the mint redesigned the die.
I still have those two 1960 and 1961 choice Unc. quarters.
Still a head scratcher on those two coins. I have shown them to many
dealers and without mentioning the type B rev. they still concur that they are not proofs.
