I have been told by a couple people that the inlaid letters H/I chip was used a club owned by Ike Hyams in Elmwood Place, Ohio. Chips were received from some of Ike's family. My question is..... I also have a serrated edge H/I chip. Would that have been sent to the same person from USPC? It seems more likely the blue chip, which is a square edge chip, would have been used in a club. Any info on the ID or the use of different molds of the same design?
