chips in Ramona, CA about two years ago. I have four demoninations. I only found one of the 25 cent. The first batch to show up was only about 90 chips total. Later maybe a month or two I found in the same antique mall another batch of about 200 more. Most of them are well used with cigarette burns which to me indicated a card room or such. I would like to say I have more info but I don't. No one I talked to, including several police departments, had ever run into these chips. So the mystere continues. Someone somewhere out there knows we just have to find them. (the antique dealer claims to have bought them at a garage sale in Southern California and had them in her garage for a couple of years with no idea where they were used.) I can still get a few of the better ones together for sets of three for $20 delievered if anyone is interested.
