Im getting mixed signals from this coin, My 1st notion was Unc, but the wingtips are telling me AU. The toning/lighting is making it tough to tell if the luster is up to snuff for an unc. Ill go MS58
From the images I would put it at AU. The eagle's breast, legs and wing tips look dull possibly from rub. It could also just be the lighting.
MS 58 is not a grade. I think if you paid 19 and sold it for 30, you are playing the game correctly. Sure, you may have been able to hold out for 35. But there are other coins out there. My grade on this I agree with AU 53 tops.
