Yes pr58, the lack of toning on the high points give the look of slight wear. But we all know that in hand it could be totally different.
Not my series, but nice looking coin! Agree with Koinjester. Is it high point friction or coin angle in the photo.
Tough to grade a proof by pics but I see a few lines and a mark or fine scratch ny the face I'd say Pf 63 is spot on
Hard to say from the image. Usually proof grades under 64 lack high mirrored surfaces unless there is a heavy abrasion in an area.
Thought it did look more like a business strike but I'm better with silver proofs then ihc ha got me!
