Agree with moxking.
Fields are nearly completely free of problems, three 'carbon' spots seen in the rim denticles.
Might be a bit of a rub (cabinet friction?) on the high points of the beard at the jaw on the side of the face, but it is so clean everywhere else that although I understand AU58, but everywhere else could be as high as MS65.
May have been a cabinet coin, with reverse showing.
Very rare in this condition.
Could be re slabbed (not my preference) or enclosed in a press seal or screw seal (preferred) acrylic capsule for protection.
