when did the currencies of zimbabwe first come in circulation
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 = 1.47 USD, 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 = GBÂ£1.[10]
Nigerian naira The naira was introduced on 1 January 1973, replacing the pound at a rate of 2 naira = 1 pound.[2] This made Nigeria the last country to abandon the £sd currency system. There was a plan to redenominate the naira at 1 new naira = 100 old naira in 2008, but the plan was suspended. The currency sign is U+20A6 ₦ Naira sign.
