Found two million dollar chips while playing in a WPT Poker Tournament at the Bossier City, LA Horseshoe casino last week. There was a charity poker tournament in the room the week before -- so it's might be attributed to that group as a possible "gift chip" for all that played that tournament. The casino does have a "Million Dollar" wall as you enter the long hallway leading to the riverboat -- all crisp, $100 bills. Maybe they are gift shop items as well. Will ask when I go there again!
