That second incused Indian is disturbing. The other two are obvious. The third could have fooled me in that moment where my eyes gloss over and I have to own the coin I am seeing.... Disturbing.
I do hope you're not buying these from China and adding another customer to their list. You probably didn't, but I just wanted to point out that when we stop buying these darn things, they'll stop making them. Supply/demand.
I'm still hoping to hear back on size/weight. Unless they've gotten the hang of striking smaller coins over tungsten cores, I can't see how you could make a "base metal" fake that was the right size and weighed as much as a real example. (And I'm quite sure the fakers already know about specific gravity. )
The densities of tungsten and gold are so close that, dimensionally we would probably never notice the difference between fakes and the real thing.
That's why I said "unless... tungsten cores". As far as I know there's still no way to actually strike a design into tungsten, so the current state of the art is a thick gold layer around a tungsten core, and that doesn't seem to be practical for small denominations. I can imagine ways to start with a large tungsten blank, whittle it down to the likeness of a coin, then gold-plate it, but I don't think it would be anywhere close to practical, and the product probably wouldn't be too convincing, either.
Click on the on the full sized image, you will see alot more that is wrong with it. Here is a genuine example. It's got so rim damage at 12 k on obverse, but it's genuine
I wish it was true, but the majority aren't purchased by people like on our forum who just want to study them. Its people who want to sell them from many different countries. One of the Ch. dealers had a buyers list shown once ( since removed ) and the number of ebay dealers were in the 10s or 100s bought each. Now some of the Ch. dealers are doing sets~ want all of the Trade Dollars, high grade but some rare ones are AU and even different chop marks, Put them in an old empty book that your great grandpa put together and ebay, etsy here you come.
