Probably Uncirculated (all the high points are clean) but am unable to see the front/top jewel of the crown; even the ribbon corners are sharp and clean. I suspect the nicks and tiny marks will down grade it; it is indeed a wonderful coin; well done indeed.
I see just the most minimal wear on the hair bun, the eyebrow and some of the higghest portions of the leaves and leaf tips. I'll say AU-58
I sent it off this AM... i personally think it will come back at 62 or 63... but that might just be me hoping!
I'd venture high AU (AU-58) and maybe low MS. The surface looks original and crusty enough. I'd get it certified just to be safe as you may have a multiple thousand dollar coin.
I mentioned in the other forum as well... Yes as you can see they are much better with photography than I am. Any one guessing grades from my quick shots was at a disadvantage and I am sure they would adjust their opinions after seeing professional photos. However, there were some that still nailed the grade!! Kudos to them for doing that with what they had to work with!
