Is This Wang Mang Knife Coin Real?

My concern is that the coin was swapped between the Ars auction and the ebay auction because $200 is a killer price for that coin. I found their Vcoins store, and, based on the prices they charge for their Chinese coins, they would not have let it sold for too much less than the going rate, which is $2000-8000. If the price went down to $200, then someone lost a major amount of money. I can't find a picture to confirm that it is the same coin.

I want you to understand that I treat all coins of this rarity and value with this level of suspicion. The Chinese have been making Counterfeits of this coin for well over 100 years, and sometimes it is very hard to tell the difference between a good coin and a bad coin. Comparing to pictures of known genuine coins makes me notice that the characters are a bit thicker than should be expected. I just don't know enough to make a solid determination.
