The Chip Rack is a reference for casino chips used in Nevada casinos. Most likely this chip was not used in a Nevada casino and that is why it is not listed. Your chip was mostly likely used in an unlicensed (illegal) casino or was made for private use. Private use chips generally only have initials on them, since your chip is more elaborate, it was probably used commercially. It could have also been used in a fraternal organization, a country club or similar establishment.

The authors of The Chip Rack also produce another reference called The Gaming Table. The Gaming Table lists known casinos, legal or otherwise, throughout the world. The initials on your chip and the picture on your chip are not referenced in The Gaming Table. Such a chip is known as a UFO. Neat chip.
