Introduced in 2015, The UNESCO Man and the Biosphere coin series features the Kogelberg Biosphere Reserve (KBR) in this first installment.
The South African Mint says:
"Greater consciousness on how we interact with nature has developed in the last half-century. UNESCO launched the Man and the Biosphere Programme in 1971 ‘to promote interdisciplinary approaches to management, research and education in ecosystem conservation and sustainable use of natural resources’. South Africa participates in this international initiative; it has six biosphere reserves.
The Kogelberg Biosphere Reserve (KBR) was registered in 1998. The map on the common obverse of the four coins indicates its location in the Western Cape Province. An enlarged map shows the reserve, which covers land and sea."
The set includes two R2 1/4oz 24ct gold coins and two R2 1oz sterling-silver coins packaged in a laser engraved double-tone natural cork box sourced from sustainably managed Portuguese cork forests.
