I recently acquired this chip and have not been able to find out any information concerning it. All H&C roulette chips from the Primadonna Club, Reno have "Del Webb's" on them. This chip is identical however the "Del Webb's" is missing. Examining the chip at first I thought maybe it just wore off but upon close inspection it was never there. Also all the "Del Webb's" chips are LCV and this chip is SCV. Showing both chips for comparison. Thought?
