i am selling many patches from a great collection of mostly colorado sheriff and police departments. I am not a patch expert, so I cant say the ages, or which ones are vintage and which ones are reproductions, please look at photos and ask any questions you need to ask. 

i will gladly combine shipping, and try to get 50 or more auctions on per round.

This listing is for 4 patches from CSU, Fort Collins, Colorado. Some have date stickers on the back but i cant verfy those dates. 3.5 inches. One says 1st issue. Some thinner, newest one seems unused.
