TCR has that chip listed as #N9351 and "attributed to Las Vegas". C&W also shows that same chip with a great photo on page 52. A "lot" of these chips was just up on eBay and got no bids (total 75 chips with a start price of $300+-). There's one on eBay right now with a start price of $25+-...ends in two days...no bids yet. Geez, am I wordy or what??? Hope this helps. Steve B.
