I agree with @dwhiz. Guess I lean towards MS63 RD. Not a bad looking coin. Looks like it could be a full RD, though if the reverse is muted somewhat it could be a RB. I think it just makes RD. The '44-S that's just out of the frame looks like it has some nice toning.
Yes sir, I will attempt to take some better photos and will post them in the toned coins thread. I basically have unc 1934-1976 PDS toned cents in old 2x2's that were slid into plastic album sleeves.
64RD feels like the right grade for the 52. Not worth a whole lot in that grade, but it is a worthy addition to an album.
