We visited WDW 4 years ago with the Family in Mid March and got about 20 or so pins. When trading, how do you know which pins are more rare than others and should not be traded one for one, or maybe should not be traded at all? I realize that trading is fun, and value is really what you like, but I don't want to feel like an idiot, if a give away a relatively rare pin for another when I should have held on to it.
