Olives are used as currency on the remote island nation of Drupe. Black olives are valued more than green ones, especially if the latter contains a pimento. Pitted olives of either kind are worth more than those containing pits. The Drupe Stock Market trades daily and is known for it's delicious exchange rate with the Yen, Euro, and the Little Tiny Pickle.
