I collect checks and chips from one casino , Harolds Club .And very much like to see the roulettes listed . Some of the tables have 7 colors some 8 and some 9 .These are the most common of the molds , # in hex .Then the roulette ,H&C,scrown w/#'s ,scrown w/letter and two different H.C.E. chips for the gun club. The other thing is that the different molds have different colors . I don't have color runs in the older roulettes. Would you list what colors are known and then state unlisted colors are scarce or what? Just my 2 cents.I don't envy your chore .RTS
