I have a "Motown Legends Casino" poker chip. It has a $100 denomination on both sides. Where do i cash it in? - real casino chips

In this chip, "says www.motownlegendscasino.net. I think it's a site about. So why not have poker chips, except for the promotion, but is printed with a par value of $ 100?" It feels like a real smart, and he seems legitimate.
