500 Francs Cape buffalo

Rwanda's 500 Francs silver buffalo belongs to a wave of large-format wildlife issues that African central banks began authorizing in the 2000s, primarily as numismatic export products rather than anything intended for domestic circulation. The National Bank of Rwanda has essentially no history of silver coinage for its own population — these pieces exist entirely for the international collector market, with the issuing authority lending its name and legal-tender status to productions largely managed and distributed by European minting and marketing firms.

KM#80 was struck at 65mm, oversized even by bullion standards, a format chosen to maximize visual impact on the secondary market rather than for any technical or monetary reason.
