Mint state? all 4 diamonds are present, but the second from top is kind of obstructed in the pictures by a different colored toning.... the last picture I think speaks well mark above the O in ONE on reverse is on the holder
Looks original to me in the pictures. I would like someone to explain they see this wear to drop the coin to XF or AU? Based off those pictures I would call it a 63/64 brown with my only concern being the hit of the O in one. Based of the first few pictures it looks like it is well struck. This is my humble opinion based off what I see in the pictures. The video does not show for me - says private.
Video did not help - as a matter of fact I think the lighting did not help at all. I will stick were I was.
