I'd keep trying some of them. Especially the peace dollars and the slq. I like all 3. I've had to occasionally try multiple times. I had a coin ngc called reverse cleaned I bought cheap come back as ms 65 at ngc a couple years later. Another was improperly cleaned unc details (an old retoned dip in my opinion) came back at ms 62. Some have graded clean at one after failing at the other and some I just have no luck with. Is all a game they play to ensure future submissions
