Well... I was the sniper. I've always just assumed that these were clever business cards used by Stardust executives so there wasn't any need to worry about counterfeiting. On the other hand I've always assumed that the Thunderbird host chips were used as $1 chips to "prime the pump" for gamblers. I guess the cage returned the chips to the hosts. I would like to learn more about the Stardust guys especially if they were mob connected.
