What you have are 2 sets of tournament chips.
Thats why there are two colors of each chip except the $1,000.
One was used in the actual Carnivale of Poker, 2nd largest (at the time) poker tournament in the world.
The 2nd was used in what we call the Super Satellites at the COP.
There is a 3rd set also $1 to $500 that were used in the 1 table satellites.
