I have 4 chips 2 Red and 2 White or Clear from The Tupperware Company. These chips are made of the same stuff they make they products of a very soft plastic or rubber and the wording is Silent Partner Tupper. My question is are these chips listed in any of the books. I would like to find the value and I may take offers on one of each color. Thanks so much for your help and Happy Holidays. Sorry I do not have pictures posted butt I still can not seem to get them uploaded correctly. Charlie
