Here is an interesting one.. I've looked online as well as in the published book, and can't understand what this one is? There is no denomination on it.. so I'm wondering if (possibly) this is either a roulette chip or a counterfeit? The color of it doesn't look right, and from all the ones I've see, I've never seen any with Horse Heads left?
Any thoughts on this one?

This is from the defunct Hide-away club in Wendover, NV.

Thanks.
