I knew some day I would have to find some neat chips...That would be today. I bought a couple wooden containers of chips at an antique shop. Mixed in with a lot of common chips were some pretty nice inlaid and C&S chips. Many had two holes drilled in them, so perhaps they were USPC Co. samples or extras. In any case it was a diverse group of chips. The shop owner said they came from an old lady whose husband had saved them. One that is really unusual is the green swan chip. I had never seen one like it before. The chips with the circles and "70" are ivory. There is no "70" on the flip side, just the two squiggly circles. All the others are the same on both sides. If anyone wants to see the C&S chips I'll post them later.
