Michael,
GREAT job on the list. A couple of things from here in the Las Vegas area. Caesars Palace did a $100 chip in addition to their $25. The Treasure Island did a $25 & $100 in addition to their $5. Stardust did a $100 in addition to their $5 & $25. Golden Nugget did a $100 in addition to their $5 & $25's. The Rio did a $25 Rod Stewart chip. The Luxor did a $100, $500 & $2,000 chip in addition to their $5 & $25's. The New York New York chip does not have the word "Millennium" on it nor does the Reserve chip or the Santa Fe, so I would think they are just New Year's chips. That's all I could catch from a quick look at your list. If I come up with anything else I'll let you know. Andy - Las Vegas
