There is also a center variation on the generic chip. Chip color in center and inlay filling the center. I'm sure this is listed in the book. a freind in Newport, Ky. came up with a few tan chips like the one I have shown here with the initials "PCC" stamped in the center. See my illustration of what it looks like. I have seen the chip. I was told that a guy with a conection to the Latin Quarter found a few of these chips. Some had the initials in the center and some didn't. Has anyone ever seen these before?
