These two pictures show all of the different C. J. Sisk Co. chips I have in my collection. I'm only aware of one additional Sisk chip, you can see it on eBay (I'm not the seller):

I'd like to have an example of the chip on eBay, however, I won't be purchasing that chip, as it is damaged and over priced. How many other Sisk chips are out there? Who can show me some more? (My chips are not for sale).
