How it all went down?

The Zimbabwean dollar was introduced in 1980 to directly replace the Rhodesian dollar at par (1:1), at a similar value to the US dollar. Over time, hyperinflation in Zimbabwe reduced the Zimbabwe dollar to one of the lowest valued currency units in the world.

It was redenominated three times (in 2006, 2008 and 2009), with denominations up to a $100 trillion banknote issued.

Use of the Zimbabwean dollar as an official currency was effectively abandoned on 12 April 2009. It was demonetised in 2015, with outstanding accounts able to be reimbursed until April 30, 2016.

In place of the Zimbabwean dollar, currencies including the South African rand, Botswana pula, pound sterling, Indian rupee, euro, Japanese yen, Australian dollar, Chinese yuan, and the United States dollar are now regularly used.

Zimbabwe’s central bank allowed its citizens to exchange the country’s almost worthless currency for US dollars. Its 100-trillion-dollar note is worth just 40 U.S. cents.(I.e less than 1usd) As at Jun 16, 2015
