Any of you Harrahs collectors know why these were made? Have the Harrahs Las Vegas location on each reverse, and The Art of Gaming was the name of an art book published a few years ago. They are plastic diamond mold chips. Four colors so they might have been part of a set for home play poker, or a tournament set? The casinos have art exhibitions from time to time so this might have been promotions.

Or maybe it's promotes the garish sculpture in the casino area that has the Texas couple with dollar bills spilling out of every pocket??

Another convention purchase... sorry, no traders.
