Pin trading is the practice of buying, selling, and exchanging collectible pins as a hobby. This often takes place in amusement parks and resorts such as Walt Disney World and Disneyland,[1] SeaWorld, Universal Resorts.[2] Sporting events, including the Olympic Games,[3] Canada Games,[4] and Little League World Series, feature long-standing pin trading traditions.[5] Hard Rock Cafe also sells a pin collection.[6]
While most trading pins are typically flat with a glossy finish, there are many types of trading pin accessory. Common features include blinking lights, hanging charms or "danglers", spinners, and bobble heads.[7]
