Pins known as badges have been worn by various fraternal organizations for hundreds of years.
This is a list of badges of fraternities and sororities, categorized by the organizations they belong to. Badges have become increasingly popular to collect, even by individuals that have no GLO (Greek Letter Organization) affiliation themselves. Groups such as the Fraternity Pin Collector Society have collected thousands of pins worth tens of thousands of dollars in individual collections while organizations such as Kappa Kappa Gamma's "Keepers of the Key" work to reunite lost or stolen badges with their original owners.
