You are seeing wear on the wing tips, Eagles breast and a few other places. What I can't tell from the photos are if this is a 1900 or a 1900-O. A little dark in that area and poor lighting. It looks like it's raised but so just can't be sure.
To be honest, I believe the photos are inadequate to definitely determine the grade. They don't show the luster very well. It's tough without having it in hand to rotate under a light. Could be anywhere from mid AU to 63 IMHO.
Once I get better equipped I can do some of those fancy animated gifs . The luster is really nice and radial!
I certainly don't have coin photography figured out! Rather spend my funds on coins.... I do like GTG's though.
