The $5 George Burns chips sold out. I don't think Caesars ever ran out of $100's. Have never seen one in play on the tables, but wouldn't be surprised if you could get one from the cage on request. I'd think something in the $110-115 range would be about right to ask for your chip. Cheap enough that most collectors would not take the time to try to get it from the casino. With the higher taxi rates, it's hard to go anywhere in Las Vegas for under $10 [g].
