Well first of all the vast majority of these so called Cal gold tokens are nothing but modern reproductions. Secondly if they do contain any gold, the size of these things is so small that the amount of gold would be worth far less than $10. You can find a good bit of info about tokens - HERE
Make sure to read up on them, Ryan. They can be tricky little buggers. It's usually a good call to only bid on the ones that have a BG#.
