Peter,
In my opinion I would say if a collector needed the color maybe he would go $500.00. There are just too many of these pieces around.

The next time you are at a chip show go from dealer to dealer checking for this piece in different colors. You will always find them for sale in both cancelled and uncancelled versions. Try the deep pocket dealers, they ALWAYS have some for sale.

The same holds true for the brown die cut metal center so called "Bugsy" chips. I remember when Jerry Wall had a full page (12) of them. He was asking a thousand per chip. Yet you could go to different dealers and maybe get one for $800.00.
You get my message - I'm sure Best, Jim
