That is a lovely coin indeed. I will have to go for a "58" as there is essentially the most minimal of WEAR. The strike is not as a proof, but I suggest that key areas reflect this: brow, cheek, nose, drapery below bust and hair on the obverse, and the top shield (left and right margins) as well as the crown on reverse show what is IMO incomplete striking and NOT wear. The denticles are also high points that many descriptors omit, and these not completely struck up either which is giving the false impression of wear. There is an odd "bag" contact, but the fields very clean overall with lustre muted as one would expect.
In short, I must admit this coin is not in the foci of what I collect, but if so would buy (at least with the usual caveat of it being a photo and not in hand) this coin priced as an AEF all day long.
