I picked up some poker chips at a flea market. They are clay, but a cheap generic looking chip. I collect all kinds of manufacturing styles so cheap is good. The only other time I have seen this style, with the circles, is on a chip from the 672 Elks Club out of Pasadena, CA. Has anyone seen other hotstamped chips from a club on this type chip? Would this variation be condidered a mold type?
