Hello to all - I just picked these up at an estate sale. There are nearly a 1000 chips with a fairly wide variety. Any info on the chip mfg, etc., always appreciated. The individual chips pictured all appear to be clay. Thanks PKRCHP61.
I hate to break it to you, but very few of those chips are clay.
The white chips in the third photo are clay (although I suspect the left most chips in that image are plastic). Very cool chips with history but most of them are slugged plastic chips available anywhere.
