The first images are what the coin looks like. The second is my poor attempt to edit the image to bring out the color. Good luck with this one.
At first glance, 64 was my thought but there seems to be a bit of a rub on reverse tail feathers. Either that or I need another cup of coffee this morning...lol. TC
The color makes think it's a proof, but I am no Barber expert. How about a really long shot at PR58. The only reason I think that is the top of the wings look soft, and you said "good luck with this one", making me think it is a tricky grade.
Looks like a proof to me, except maybe the wing feather detail. Still, I'm going with PR66 and I'm prepared to be mocked.
I just love the way the proofs exhibit that full strike for Barbers, and you really get to see the design. Good thing it's in a holder, might cut your fingers on those rims! Proofs are way out of my league for grading, but I'll take a shot anyways. PR65
