Zimbabwean dollar
The first Zimbabwean dollar was introduced in 1980 and replaced the Rhodesian dollar at par. The initial ISO 4217 code was "ZWD". At the time of its introduction, the Zimbabwean dollar was worth more than the US dollar in the official exchange market, with 1 ZWD = US$1.47, although this did not reflect the actual purchasing power it held. As a result, in both the official and parallel markets, the currency's value eroded rapidly over the years, and by July 2006, the parallel market value of the Zimbabwean dollar fell to Z$1,000,000 = GBP £1.
