Of all the chips I have in my possession, the most treasured are those that my granddad played with at home and let us play tiddly-winks with when we were little. Basic, plastic chips, they're not of great monetary value but sentimentally they are priceless.
Old chips with history, whether clay, MOP, ivory or "other" are far more intresting to me than the ones produced in the past 20 years or so.
