From the movie "Tomcats". Probably some of the more desirable prop chips as they have that Hard Rock connection.

There is one small casino scene in the movie that was filmed at the Hard Rock LV. The movie production company intended to use actual HR chips in the scene, but were told shortly before filming that they could not film actual chips. The set designers made up some fake HR chips for the film modeled after actual HR chips, but changed the casino name to "Hard Road". Very few of these exist.
