Have these in at our host right now, coins are more PL in person than in the photos where they look dull gray. Guesses on the grades? Only 7 sets in the pop report from MS61-65.
Hard to tell from pics if cleaned or not, which it looks a bit likely. If not then 63-4 PL.
These are the sellers pics, they definitely look better in hand, surfaces are clean but not cleaned (hopefully)
The images look like scans, but I would imagine that any hairlines on them might show up more easily since they have been dipped.
