when did the currency of botswana came in circulation
Botswana pula The pula was introduced in 1976, replacing the South African rand at par. Despite a 12% devaluation in May 2005, the pula remains one of the strongest currencies in Africa.[citation needed]
South African rand The rand (sign: R; code: ZAR) is the currency of South Africa. The Rand is subdivided into 100 cents (sign: "c"). The ISO 4217 code is ZAR, from Dutch Zuid-Afrikaanse Rand (South African Rand). The Rand is legal tender in the Common Monetary Area between South Africa, Swaziland, Lesotho, and Namibia, although the last three countries do have their own currencies pegged at par with rand.
