I'm looking for information on a chip. Here is a description:

It's yellow/mustard color, is stamped with M & O and a small star on each side of the word club under that. It lloks to be either plastic or ceramic (it's very light weight). There is no denomination on either side and both sides look the same. I'm guessing it's from an illegal casino. I picked it up in Salt Lake City. Any infomation someone might have would be helpful.

Thanks
