Does anyone know where any of these chips are from? The yellow one is the same chip, just different initials on each side. The story I got was that they all came from an estate from Cairo (Chicago),IL and that the owner lived there most of his life. The BC chip was supposed to be from a "Bombay Club" in that area. This would make sense given the oriental style of the letters. Has anyone ever heard of this club? Is Jimbo still out there?
