The “new” Fort McDowell 25 cent chips are used in blackjack game called PERFECT CHARLIE. They are used as a MANDATORY side bet like in Caribbean Stud. If you make a suited 6-7-8 21 you win a jackpot. The game sucks but I think it is one of the best looking 25 cent chips ever. I did not find any mold variations like in the 50 cent chips.
