I do not have any hard evidence on this chip. I just remember when I was working for Chip Gallery in the Gamblers General Store a young man came in one day and in the course of the conversation he introduced himself as a relative of Ernie Primm and told me he remembered seeing some of those chips in Ernie Primm's desk drawer.
Sorry I can't be of any real help on this. I was hoping someone might come forward with
some better information on them. Janice O'Neal
