Those auctions were a joke. The guy probably had a friend bid up his rare games so he could keep them, because he didn't get the prices he wanted. The same exact games have sold for 1/3 of the price several times in the last few months. If there are a few more instances of sales at that price, maybe I'll believe it, but I think this is an isolated event.
Only other possibility is Bill Gates and Warren Buffet both decided they must own all TG16 games last week.
