You are missing the blue one.
CSI had them made. 400 made of 5 colors. They were used in one scene only. It was a poker game filmed at the Palms. A guy died at the poker table.

The chips were made in the week before filming. I approved them for the Palms.
I would be very careful paying a price for them. Anyone could make the same chip.
I have a set, I know was made for and used by CSI.
I could not say that about any other set.
