Hi John.... everything done...
to a chip is history. A drink spilled stain, a cigarette burn, an oiled up chip from hand use, a club owner washing his dirty old chips, and even a Dave W. special. I don't think you will ever know a chips total history. My guess is that some day a few chippers will consider a Dave W. special a big prize and those chips will sell and trade at a premium because of their HISTORY (only if you can prove it is a true Dave W. chip). History is everything that happens to a chip, everyone just picks the history they like, some collectors like dirty old beat up chips and some like them looking nice, I have both types in my collection and prize them all even if I don't know their total history, I just like chips and sometimes the history is fun.
Having fun Steve
