I know nothing of the seller so I have no facts on which to base an opinion but I have watched a bunch of auctions for these chips and the seller has re-listed a new auction for the same chip right after selling one, on a few occasions. In December the die cut Flamingo and the Barneys were both examples of this. Strangely, The Flamingo sold for $5K and the immediate re-listing was for $2K. I suspected that a shill bid was placed (bidders ID had 0 feedback and 0 prior bidding activity) on the sold oneand no-one jumped on it, hence the lower re-listing value. Additionally,the barneys chip was purchased after one bid...and you guessed it, it was the same bidder id with no history. It may be that a collector was willing to pay the asking price and no-one else was and created a new ID to conceal his identity but It did give me pause. It is also possible, there are more than one of each for the ones shown in your post. Either way, I just found this a little thought provoking. Good Luck either way.
