Every single auction has has a conflict of interests to some degree on EVERY auction, they want to authenticate the item so it will sell. Case and point on historic auctions last auction when they sold for over $3,000 cobined a fake Carnell Williams and a fake Michael Clayton. i have ran into this problem with almsot every auction house, the point is that all buyers should do their homework before puchasing and NOT leave it up to a piece of paper that magically becomes a COA.
