Bus Fare In Zimbabwe Is 3 Trillion Dollars

"HARARE, Zimbabwe – A woman pays her bus fare with 3 trillion in old Zimbabwe dollars — the equivalent of 50 U.S. cents. The collector accepts the brick of neatly folded bundles of a trillion each without bothering to count the notes.
"No one seems to worry, and it works," said the woman, Lucy Denya, a Harare secretary who says she's seen police officers using old notes to board buses."
"Outside the cities, where hard currency can be hard to come by, Zimbabwe dollars are used like promissory notes in small transactions. And trillion Zimbabwe dollar notes, the world's biggest denomination bills, are a hit with collectors, selling briskly on eBay. In Zimbabwe, they change hands like tokens or IOUs."
