Has that fakey-fake China look. Does it stick to a magnet? I've read there are some lightly circulated (AU) examples out there but I doubt any this worn. The rim is a dead giveaway tho. Gotta be careful with Trade dollars buying them raw.
Counterfeits are often made from silver and can be the correct weight. You need to try and get your money back. The coin is not a circulated proof as noted the denticles are wrong and the coin has cast bumps that are typical for counterfeits.
