Those are insane prices - can't believe anyone ever paid that - even if it belonged to someone famous.
Makes you wonder if they did the scheme of "putting ii up for sale on ebay. Having someone they know (or made up) bid and win it. Sale falls through but shows that it sold for that price in order to raise values." That way they don't have to pay Ebay for the sale either and "unknown/fake person" gets kicked off of Ebay.
