I always look through the pins. A fare amount of them are gold. I gave $7.00 for a small bag of pins that had this one in it. I sold this one at auction and it got $68.00 I think? I wished I kept it. I now keep all the gold pins I find if the price is right. The ones I don't keep ( like plastic pins) from the bag lots if that's how I purchased them I give to my daughter, as her and her friends do a fare amount of geocaching and add those to the caches. They'll stay out all night in the summer time geocaching. I've only gone geocaching once as she went on the road with me and we looked for cashes along the way. I will say it's pretty fun. If my girls we're young again I'd do that as a family summer vacation road trip. Now their at the age to be married and that's not happening, they run these poor boys off all the time. I need some grandkids to have some fun with, Like going geocaching.
Folks sell these lot of pins on ebay as geocache stash. You could maybe double plus? ? your money selling them that way, with the exception of the bronze California pin. You need to find out what that ones about. Could be worth something?
