I just got these back from being graded by NGC and am listing for you this 2023 Reverse Proof Peace Dollar in perfect Reverse PF70 condition. NGC has only graded 4227 so far in this condition. I realize that you may find others out there cheaper but NGC has already put a Market Value on this coin of $600 so I don't feel my pricing is unreasonable. Many of those already listed did so prior to NGC releasing their pricing info.
