I purchased these before the film was even released. I was a little nervous as I wasn't sure they were actual prop chips from the film until I watched the movie. When I saw Tyson was in it, I was so happy. I don't think anyone (including the guy I got these from) realized how popular the film would become. I bet they would be very popular on . I don't think there are many of these out there. If you remember the movie, there was only one scene at the BJ table (copied from "Rain Man"), so I doubt a lot of these props were made.
