This Holiday Las Vegas error doesn't trade very often, Greg, but seems to be valued around $50-75. I would guess Las Vegas chips have a larger following and and error from there might go for a bit more. Then again, there aren't that many errors, and an error collector might pay about the same for any error just to put another one in his specialized collection. An auction would be the way to put a value on it if you want to sell.
