I received these chips on consignment just before the convention. I sold a few there and again on ebay a couple of days ago.
Here are details of what exists and what is available:

$500 denom - I had 5 of the 7 known examples. Four of these were very fine and one had a small defect. The first four have all been sold.
The one I have available has a small defect on the inlay on the reverse side between the T (of desert) and I (of inn). Like a tiny fingernail impression. Other than that the chip is just a little dirty but a very collectible and rare example nonetheless. The previous ones sold for $500, $460, $455 and $450 + shipping/insurance. I will take $350 shipped & insured for this last one.

$1000 denom - I had 6 of the 7 known examples. Five of these were very fine and one had a small defect. 3 of the vf and the defective have all been sold. I have 2 very fine examples available. The previous ones sold for $750, $702, $698 and $508 for the small defect. The vendor would accept $650 each shipped & insured for these last 2.

$5000 and $25000 baccarats. - I had 3 of the 4 known $5k's and all 3 known $25k's. I have sold 2 of each. I have the one of each shown available and the vendor will consider offers. It is not fair for me to disclose how much the buyers of the 2 sold pairs paid, and to be fair to them, no offers will be accepted below the price they paid. All of these chips were in real nice condition.

$25 and $100 denoms. Not so rare but I do have a couple each available in very nice condition. $25's will be $65 shipped, $100's will be $100 shipped. They often go for double that on ebay.

Email me if interested in any of these.
