Only Nevada casinos and only with a Casino name on them. I'm not looking for any generic type chips even if they were sold in a gift shop.

Here's an example (front and back shown):

There are many others like these. El Cortez has a set out, and Planet Hollywood. The Palm Jimmy Tipton Naughty Nitey chips would also fall under the catagory since they are sold in the gift shop.

So....no generics, no non-nevada, and they must have the casino name on them.
