Jill,
The dark brown roulette is First issue from Harrah's in Atlantic City and a nice find. This is the first dark brown Geometric Triangle design roulette I have seen. I will add this to my revised A.C.Roulette Catalog. Value of this chip is around $40 to $60. LMK if you want to sell or trade it.The other chip may have been used in A.C.,BUT I'M NOT SURE.
