Nice and frosty. Those die polish lines prolly give a very proof like look. She has a pretty clean cheek with what seem like a few frost breaks. She is kind of baggy. I will go with 64PL. I think the contact marks limit her from a 65 but the luster may push her into 65 territory. With it being an 1882-S which may be graded more critically... 64PL is my guess.
The reverse is questionable. It’s possible that PCGS is using the + designation in a similar manner to the way that NGC uses the * designation for just miss PL coins. This is a tough coin to grade from photos.
All PL and DMPL Morgans are very difficult to grade from a photograph. Looked prooflike to me, but I am not the TPG—their call.
That is what I thought too based on the picture. And I think 64+ is also a fair grade as there seem to be enough hits/marks to limit it from reaching a gem grade (although I've seen some like these get into 65 holders).
