The Absolute Worst Currency in the World: Zimbabwe
$1 USD = 642,371,437,695,221,000 Zimbabwean Dollars
It's hard to keep track of just how fast the Zimbabwean dollar has fallen since the government reinstated electronic parallel market transfers on Nov. 13, but even before that the currency of Zimbabwe was the most worthless in the world.
While the official rate on Monday was 19,393.94 Zimbabwean dollars to the $1 USD, the old mutual implied rate, generated from comparing the Zimbabwe and London stock exchanges, valued the currency at more than 642 quadrillion to one.
When the currency was revalued this summer, an egg cost about $35 billion Zimbabwean dollars.
