Hey there, This Buffalo recently came to me and I’d love input. The flip says 1921S?, but it looks to me like it is, in fact, a 21S. It definitely has a cool lamination error on the reverse. Would love grade input as well. The flip said AG2/3 which I think is way low. Thanks!
From what I am seeing, that last digit does appear to be a 1, so I'd say you'd be right in your assumption. Nice grab!
Sure looks like a 21S to me. 7 is the closest shape in Arabic numerals, and that doesn't look anything like a 7. As for Grade - AG-3 is actually probably the correct grade. Grades get a bit loose on these since this is a key date, but whenever the rims are worn down into the letters (obverse and reverse), I have a hard time calling it anything but AG. You could make an argument for G4, but I absolutely can't go any higher than that.
