These three colored tokens are from my "Color Token" collection which contains metal tokens actually intended for play in slot machines, manufacturer samples of various styles, and advertising tokens made with colored designs. All are in SU condition.

These are from Colorado and Arizona and I believe were intended for slot play. Two from Colorado were used when a voter amendment was approved allowing low-stakes play. State of gambling in Colorado from Wikipedia:

Since 1991 Colorado has permitted limited stakes gaming in Central City and Black Hawk in Gilpin County, and Cripple Creek in Teller County. The state constitution currently places the following limits on gaming:

single bets cannot exceed $5
only slot machines, blackjack, and poker games are allowed
casinos must close between 2:00 a.m. and 8:00 a.m.

Amendment 50 allows Central City, Black Hawk, and Cripple Creek to vote to change the existing gaming limits. Each town may vote to extend the hours of operation of casinos, to add the games of roulette and/or craps, and to increase the amount that can be wagered on any single bet from $5 up to a maximum of $100. The towns may vote on changing any of all of these limits.
