Paul, I'm sorry I took so long to respond to your post. They most certainly were used at the Holiday in Reno and made about 1988. They are not in TCR as they have not been seen by Ernie, Michael or myself. They have not appeared in any auctions or sales lists that we have seen. C-W list 6 colors in their book at 8.00 for average condition. The color that you did not scan is Yellow. They WILL be in TCR-9.
