Pathfinder: "Paizo GenCon 2013 Pin Set" [RPG]

The Paizo GenCon 2013 Pin Set is a set of five round pins with the traditional "don't mess up or you'll blood" clasp on the back.  According to the website, the pins were released to celebrate Mythic Adventures, Season 5 of PFS, and the Wayne Reynolds' book Visions of WAR.  One of the pins depicts a goblin, one depicts classic Valeros, one depicts the PFS Season 5 "Year of the Demon" logo, and the other two are more Wayne Reynolds art.  I can't really foresee a use for these pins, but a collector's gotta collect, so in my display cabinet they'll stay!
