$100,000,000,000,000

An honoree in the fiat currency hall of shame. The Zimbabwe $100 Trillion bill was issued in 2009 during one of

history's worst hyper-inflationary events.

Zimbabwe's official inflation rate hit 231,000,000%, and the bill was worth the equivalent of 0.40 USD--not even enough for bus fare.

Zimbabwe has since redenominated their own Zimbabwe dollars, as well as "dollarizing" and adopting the US

dollar as an official currency.
