Paul excluded Nevada chips from his price guide. I believe those you show are all from Nevada so the $2-3 prices wouldn't apply.

I had not thought about pricing non-Nevada chips since I usually only end up with $2.50's and inlaid fractionals outside the state but the guidelines are pretty good. I don't collect Colorado, but from the prices I've seen paid, the guide lines would be out the window. Many of them sell for multi-hundreds, although I've never understood why.
