Pogs were a game kids played around the time the World Race came out. Most cars came with the things (I think the movie packs did not include them or the comics). Many of the pogs (or 'tokens') had a peel off back to win instant prizes (though I never saw anything but ''Sorry please try again...''). I believe the pogs in the cars sold outside the US did not have the peel-off back.

The pogs are printed with the same images on the front and back.
