Disney’s got this racket going they call ‘pin trading’. Stores sell hundreds of different types of pins for people to collect and trade. In the parks you can approach employees and trade one of your pins for one they are wearing, and Disney ‘seeds’ rare pins this way. There are pins based on almost anything – pins for every ride, Disney film, character, TV Show, park, resort etc. Many pins are exclusive to certain shops or parks and they are ‘retired’ often and many seasonal pins exist as well. There are so many even if you wanted to collect a single character you’d have dozens. Trying to collect them all ($7 apiece) would probably be impossible. It’s obvious from the pin-filled lanyards on the necks of many guests this is very popular!
