Zimbabwe 100 Trillion Dollar Note, 2008

The Zimbabwean 100 trillion dollar note is a banknote issued by the Reserve Bank of Zimbabwe, bearing the face value of one hundred trillion dollars (100,000,000,000,000 dollars). Belonging to the third Zimbabwean dollar currency, it was released into circulation on 16 January 2009 alongside denominations of ten, twenty, and fifty trillion dollars. Issued amidst severe hyperinflation, it served as the highest denomination of the 2008 series and represents one of the largest numeric currency denominations produced in world history.

The note formed part of the third dollar series that commenced circulation on 1 August 2008 following the country's second currency redenomination. Its period of active circulation was exceptionally brief; on 2 February 2009, a fourth Zimbabwean dollar was introduced, which evaluated the note at one hundred fourth dollars. Although originally intended to co-circulate until mid-2009, the national currency was suspended entirely on 12 April 2009 when multiple foreign currencies were adopted. Despite the cessation of official circulation, the note remained formally redeemable through the Reserve Bank until 30 September 2015.

Measuring 148 mm in width and 74 mm in height, the paper banknote is predominantly blue with peach accents. The obverse displays a central depiction of the Chiremba balancing rocks (Domboremari) near Epworth, Harare, a recurring design motif chosen as a metaphor for balancing development with environmental preservation. The reverse illustrates Victoria Falls on the left and a Cape buffalo on the right. Because of international sanctions, modern security devices such as a traditional watermark were omitted, with the note relying instead on a patterned stripe and a silhouette of the Zimbabwe Bird printed in optically variable ink.
