A: Hi, as far as I know there are 108 $100 denominated chips. I own 103. There is one (1) for sale. Hope that helps? Thanks for the interest!

The entire thread is very interesting and worth reading again. It is pretty clear that the 108 $100 chips were not the total found so more than one person had some or the seller told a little fib.

I also think I recall Pam, or someone, posting an ad for the Sunflower from an old phone book, or something, that included an image very much like the one on the chips. Clearly I don't remember it very well though...
