bottle caps?
Lisa has a 3 hour task to and the reward is a bottle cap. Fatov is tapped and gives out bottle caps too!

Like Nick said, you get bottle caps when you get a pin that you've already got in your collection. 4 bottle caps each time you get a repeat pin. You can then exchange 30 bottle caps for one pin that you don't have in your collection. Not much sense in it, though, since you can have two pins every 3 hours (one from Lisa, one from Fatov).
