For those who might not have seen them before, these are some of the C.J. Sisk samples with other die-cut inlay shapes. I don't know what you call the shape on the black chip... maybe a "knock off hub" inlay?

Sisk was a separate part of Paul-son that sold to non-Nevada casinos, mainly California. I don't think I've heard where the name came from; the C.J. could be Christy and Jones.
