I got these square edge generic roulette type chips years ago and assumed they were not club chips or if hey were they would be unknown. Some time ago I was advised (by whom I remember not) that they were from a California club. I can not find them in Eastmas, TGT, nor in Staeffler's and so assume that they are either not cllub chips or if so are unknown. But if any person can attribute them I shall happily send that person one of them--his/her choice free.
