I was kind of drifting between 64 and 65 so I voted for both. Nice coin, thanks for posting it. Be safe
64. Just too many marks on cheek, eyebrow and hair and a few in the obverse fields to make it a 65. Reverse is very but appears to be weakly struck to my eyes but I don't it that is typical for this coin. Nice luster and the toning is not super-attractive but not distracting, at least to my eyes.
MS-64. Commemoratives never cease to humble me. Clearly, I must "up" my game and reference library. A stunning coin.
Looks a lot like mine. The darker toning on the reverse makes it a little hard to read, but I'll say 65.
