Obverse appears to be an earlier die state paired with a much later reverse die. Fields on the obverse IMO are near-spotless while the reverse shows a few contact marks. Higher devices have evident bag marks but little if any signs of wear. It is a shame for the 2 marks on the cheek, since without them it would have fantastic eye appeal. I would say ms-64, (maybe) 65 depending on who sees it. Thoughts?
First off you cannot have an AU grade because of a weak die strike caused by a worn die. With that said there are too many nicks in the portrait then on the reverse there is a nick cutting the third pillar. This is a "Mint State" coin but in my opinion with all that is going on with the portrait MS 60 is the best I could give.
