This is probably an early issue from the Casino de Potato located in Spud Idaho. This casino was run by a religious order, the Chip Monks and the French Friars.

They made the gaming process very easy. Instead of having slot machines and table games, you just put your money in the collection basket and saved a lot of time.

Chips did not come in racks at that time but could be bought by the bag. All same color, but various flavors.
