You are purchasing a LOT OF 50 pogs - 49 pog pieces and 1 metal slammer with yin-yang design. These are themed as Playing Card theme (Jack, King, Queen, etc) and superheroes (not sure what collection) with a few other assorted designs including Jurassic Park.
Many of these do have markings on the back, some have signs of use, they are otherwise in good shape overall.
