I have a bunch of these different chips from Doug. The story I got on them was that he had a bunch of old blank mold chips and to keep them from getting into the hands of someone who might use the "Blanks" to make phony or counterfeit chips, Doug merely hotstamped his name on them and put them in his "Junque" box for sale as mold varieties. I will post a scan of the ones I have later - wife wants to go to town and don't have time to scan now.
Till later,
Jerry
