For starters, the major problem with it is the denominations on the two sides are different. On the English side, it says "7 mace 2 candareens", which is the weight (in traditional Chinese Imperial Treasury units of weight) of a silver dollar. However, on the other side, the denomination is given as "1 tael"; 1 tael equals 10 mace. It is impossible for a genuine coin to be both 1 tael and 1 dollar.
The province-names are different on the two sides as well; the English side claims Hupeh Province, but the Chinese side claims Fengtien Province.
Conclusion: The two sides are from completely different coins; the fake-makers have simply been careless in making sure the two dies they used to make this coin were matched up properly. Which is fairly common for the cheaper fakes that they make.
The weight, at 37 grams, is too heavy for a dollar (should be about the same as an American silver dollar, 27 grams) but 37 grams would be about right for a tael. Tael coinage never really progressed beyond the "pattern" stage in most Chinese provinces, with the Imperial government adopting the dollar standard instead. A genuine pattern 1 tael coin from Hupeh Province would be worth tens of thousands of dollars;
This one sold for $21,000 ten years ago.
