The Prestige set consists of the R10 yellow-throated sandgrouse and R10 white-backed night heron bird coins, as well as the R5 orange tritonia and R5 grass crinum flower coins representing the Waterberg Bioshpere Reserve.
The 2018 colour coin range represents the beautiful fauna and flora of the Waterberg Biosphere, situated in the magnificent Waterberg district in Limpopo. As the name implies, The Waterberg serves as a water reservoir for this arid region.
There are four main river catchment areas which provide water to an area of over 40,000km2. The Waterberg Biosphere Reserve is an area consisting of low mountain ranges and escarpments with poor soils and a relatively low level of economic activity. Habitats are sufficiently represented to ensure that the current high biodiversity is maintained and the low human density ensures large areas of unspoiled wilderness and open spaces are a main characteristic of this biosphere reserve.
All four coins are one-ounce sterling silver. |
