Jeff--Extremely interesting. The thing I find most confusing is that a PSA9 Mantle sold three times in six months, all in Goodwin auctions. The first and last sales were not abnormally priced, just the second. Do you know if these were all the same card or if they were different ones? If the same, that would make your analysis even more damming. Also, while it is always possible that a consignor had a friend shill up his or her lot, you need an underbidder to get this high. Unless there were two shills that still implies at least one "agressive" bidder out there. If you are implying that Bill ran these up, why would he do it on the middle auction but not on the other two?
