Pin trading and collecting
Pin trading and collecting is the practice of buying, selling, exchanging, and collecting enamel pins (or lapel pins) as a hobby.
Enamel pins are commonly sold as souvenirs, branded merchandise, fashion accessories, and artwork.
Trading often takes place in amusement parks and resorts such as Walt Disney World and Disneyland, SeaWorld, and Universal Resorts, or at sporting events, such as the Olympic Games, Canada Games, and the Little League World Series.
While most pins are typically flat with a glossy finish, there are many types of accessories. Common features include blinking lights, hanging charms (or "danglers"), spinners, and bobbleheads.
Pins are sometimes manufactured in limited editions to increase demand.
