Hi, I normally post in the Ancients section but a friend of mine has this coin, I am sorry the photos are out of scale but this is all he provide me with. My question is what is it? A common coin? I am just trying to help out an older friend so for give my question if it is overly simple, I just have no knowledge on modern coinage (post 1500). Thank You in Advance.
That would be a fake trade dollar. Genuine ones were not minted until 1873 so the date is a dead giveaway.
