20 Cents Limpopo Transfrontier Park

This piece belongs to the South African Mint's series commemorating the country's transfrontier conservation areas — cross-border parks established under bilateral agreements that, in the case of Limpopo, united South Africa's Kruger National Park with Zimbabwe's Gonarezhou and Mozambique's Limpopo National Park into a single 35,000-square-kilometre protected zone. The formal treaty was signed in 2002, but the Great Limpopo Transfrontier Park had been a political ambition since the late 1990s, driven partly by post-apartheid South Africa's push to normalize regional relationships.

The denomination — 20 cents — is nominal fiction for a proof silver issue never intended for circulation.
