The Wilbur Clark DI token is 1214.0 in the Nevada Promo Token Book. Valued at $25-30 (20 years ago). The one in the book doesn't have the loop for a ribbon. Does yours look like it might have been soldered on? Token is Nickel Silver (no silver content). I sold one about 3 months ago without the loop for $30.

The Castroville $20 chip is not in Pfaender. I haven't seen it either. If you can find someone who collects CA 20's, it's probably worth $20-25... maybe a bit more.
