I'm not even sure what I'm looking at with those pics. The surfaces look "flat", indicating the coin was altered, but it could be the photos, and it is impossible to read the luster, which would be the ultimate clue. If it looks that flat in hand, no question it was doctored; probably whizzed to obtain that unnatural appearance.
Its another silver dollar to me. Attempts to clean or polish silver coins, whizzing, is ...its not for me but you think 55 ? Good hair, but its breast feathers on the reverse detracts a great deal for 55. To me. It takes it out of AU doesn't it ?
