Those are a great assortment of "Avalon" chips ... including one with photo of the "Casino" at Avalon, Catalina Island, CA. (For those who aren't aware, no gambling at all at this Casino. It's an entertainment location for dancing & more, often near a body of water.)

The fictitious Avalon chip I'd like to see is a chip that reads: Albacore Club / Avalon, Catalina Island, with flag logo of an albacore fish and "A C" beneath.

In my imagination, the Albacore Club chips would need to be elegant Crest & Seal chips in various colors, complete with flag logo, reminiscent of the off-shore gambling boat chips such as the SS Tango, SS Rex, etc.

Stay with me now . The fictitious Albacore Club was featured in the movie Chinatown, where Jake Gittis goes to meet Noah Cross at his club on St. Catalina Island. The movie even featured a plaque on the wall saying Albacore Club, plus a nautical pennant flag featuring an albacore fish and the initials "A C" beneath.

See the 2 relevant pics about half way down on this movie site:

There's even some T-shirts available on the web with the Albacore Club logo on them.

Of course, the real location is of the Tuna Club, an actual private club on Catalina island.
