The club in El Cerrito is the obvious one, but I have no provenance that the chip was from there. I doubt the "90" or "Ninety Club" is unique, but the one in El Cerrito was sure a popular one. It was raided MANY times throughout the 1930.

Since I don't have any info, I don't put any notes in the ChipGuide because it would be shear speculation and once its noted, it becomes gospel.
