One of those oddball chips where you have to remember the name of the place rather than the letters on the chips!

Not sure what the Fish had to do with the card games. If they jumped out of their tank, they'd flop aces? And flop everywhere else!

Onyx was from Roseville.

Chips from both J & J and Onyx have been found in various colors (not necessarily a big surprise). Not super-super-rare to find at least one color but I don't know how common some of the colors might be.
