My copy of Armin Pfender's Calif Guide (at least a year out of date) lists the value of the non denomination chips as $5-$9. The $5 chips is not listed. The $20 chip is listed as $10-$22. The $100 chip - if you ever find one - is listed at $10-$25. The chips that Doug showed list at $75-$150 but I suspect that some more must have been found as the trade I made for the one I have wasn't valued that highly. I think I bought the ND one on eBay for about $6 - but I am not certain.
