Now we know it's a fake. That is far too low for a genuine example.
I disagree with this as a general statement. The amount something sells for is not a litmus test as to whether something is genuine or not. It could depend on any or all of the following:
1. The venue
2. The images and description
3. The return/extension policy
4. The reputation of the seller
5. The nature of the bidders and their level of expertise
6. The timing
7. The particular risk tolerances of the players in question
Sure, the amount garnered can certainly *imply* whether an item is genuine or not, but it is hardly definitive. I've bought enough items both in eBay
auctions that run to completion and through major auction houses at bargain prices well below market value to know that it all depends who's bidding or not bidding at that particular moment in time.
