I can't tell luster in the photo, and it is hard to distinguish wear from glare. It's also hard to tell if there are surface issues, like cleaning.
But I agree that there might be AU-level wear above the ear, etc. If so, I'd say AU50 without luster, AU53 with luster. The spot in the obverse field might be grade limiting.
The variety is easy: There's only one for this date, C-1.
