It's highly unlikely that the final bid on this Casey Anthony Mask is legitimate. The surprising fact is that this is actually a thing, that there is a mask of Casey Anthony floating around and that people actually bid on it.

A quick check of the bidding history shows three bids in a row that escalated the price from the more "reasonable" $45,000 dollars to $700,000. All three bids appear to be made by the same user ID.

Equally questionable is the fact that the mask got up to $45,000 in the first place.

A bid on eBay is, according to the site's guidelines, a legally binding contract. A quick look at the buyer's info, however, reveals one bid in their history and that was on the mask.
