50 Francs Cape buffalo

Rwanda's National Bank issued this piece as part of the African Wildlife series, a collector-driven program that began gaining traction across central African issuers in the early 2010s largely because sovereign mint partnerships offered smaller nations a revenue stream from bullion premiums rather than circulation. Rwanda itself adopted the franc as its post-colonial currency in 1964, replacing the Rwandan-Urundi franc after independence — but by 2015, commemorative silver issues like this one had nothing to do with domestic monetary policy and everything to do with the international bullion market.
