I just fast forward through my tape of "The Song of the Thin Man" looking for chips. The only chips are at the very beginning . The first shot in the movie is of the gambling boat with big sign "S. S. Fortune." Then you see people playing roulette, handling chips. You never see the design of the chips. One guy is holding a chip which faces the camera, but you would need an FBI lab to zoom in on the design, if even they could do it.
