Steve - all 3 of the $1 Mystic Lake chips are currently in use. The only cash value chip that isn't available at the casino is the $5 4th Anniversary chip. That chip was in use only a short time, unlike the Millennium issue, which is still on the tables. Mystic Lake also has a generic no cash value red $5 chip used for teaching customers Blackjack at their "Blackjack University" table.
