Zimbabwe $10 Billion Note Would Be the World's Highest Denomination

By Nutmegcollector

On December 19, 2008, Zimbabwe issued a new 10 billion dollar note. This denomination took effect after two previous currency revaluations.

In the August 2006 revaluation, 1 new dollar was exchanged for 1,000 old dollars. In the August 2008 revaluation, 1 new dollar was exchanged for 10 billion dollars. The two currency revaluations dropped a total of 13 zeros.


So the current 10 billion dollar note would be 100,000,000,000,000,000,000,000 (23 zeros) pre-August 2006 dollars.

The current record for the world's highest denomination is Hungary 1 Milliard B- Pengo, 1,000,000,000,000,000,000,000 (21 zeros).
