The chip is from Caesars Atlantic City - Series III that was on the Tables in 1995. There were Tables 1 to 12 in 7 colors - I have all 84 chips in my collection. Also I have a #14 Brown Chip from this same Series.
Scan below is from "CATALOG AND CHECKLIST OF ATLANTIC CITY ROULETTE CHIPS" which I published in 2002.
Take care,
