I came across these chips the other day at a yard sale, I figured they were decent chips just because they were crest & seal. I looked at a couple of c&s websites but couldn’t seem to find these chips listed. Are these rare, or really common and nobody has gotten around to putting them up.Since I don’t really do anything with c&s chips I decided to try them on Ebay. The auction is starting tonight and going for 7 days. The auction number is: 6203171268
