As you may or may not know Gold Indian Half Eagles have very weak mint marks. What do you think this one is?
I see what I think you are looking at, but it is way too close to the arrow. If there was a mint mark there, it should almost touch the rim. I'd have to call it a Philly.
Looks like an S to me. What many folks don't realize is that the mintmark was the only raised portion of the Indian quarter and half eagles. Therefore, the mintmark wore down very quickly.
