Is this die deterioration on the mint mark or is this doubled? There is a long die crack that runs from the U to the I in AMERICA.
It's mechanical/ejection doubling on the Mintmark. That, and the die crack, are very common on 1964 silver Quarters......
Agreed Fred, I have a couple that looks just like yours, Dollar. I believe both of these are 64's, one might be a 57. Pretty cool find tho and they're silver!
