When the apparent difference in grade is so blatant between faces, one obviously has to make allowances for the weaker face. Coins don't just wear on one side. That said, I'm seeing a bit more wear on the reverse than most of you. There's no flattening in the features, which one might expect of a weak strike. All details are nicely rounded. Probably overanalysis of "nice but non-professional imagery," but I'm calling this one on the upper end of AU55.
