AU-58, but I want to write 62. One thing that bothers me about seated liberty coins is the head position. It is too far toward her left shoulder and appears awkward and out of balance.
Recurring problem with me; I seem to see wear where there really isn't any... I'm seeing wear on the eagle's head so I'm going to go with AU58, for me it's really difficult to tell what is wear and what is just lighting flux when I don't have the coin in hand...
It looks like it has a clash in the shield. If so, how did that happen with no other clashes visible anywhere? I am very skeptical of the coin's "look". It looks quite "shiny". It could just be the photographs. On technical sharpness, I'd call this an AU-58 and maybe a slider. But as said, I am ambivalent on this coin. So, I'm not going to opine unless additional photos are posted.
Looks like high AU, but unfortunately it was either cleaned or polished. It has this shiny look most (all?) improperly cleaned coins have.
Yes, the pose is anatomically impossible. The human neck actually attaches to the spine in the middle of the back, not the shoulder. I've always been amazed that nobody seems to notice that.
