I have brought this chip to the attention of other collectors in the past, but mistakenly read the letters as "E8S" or "E&S". I know now the chip reads "F&S".The chip is definatly from CA. There was an establishment called the Smoke Shop Club in Dunsmuir,CA in the 60's which used a square in circle mold. Could this chip predate/postdate that chip?? Gene, anyone, Help??
Thanks, Duke
