10 Francs Rhinoceros, palladium

Rwanda's palladium wildlife issues occupy a strange corner of the numismatic market — struck in a metal with almost no minting tradition, for a country with no domestic palladium production, sold almost entirely to foreign collectors rather than circulated. The 0.311g specification is the smallest practical palladium planchet commercially viable, and the .999 fineness is standard for the metal's modern numismatic use, where alloying is rarely done.

Palladium was briefly fashionable among boutique mints in the 2010s following its price volatility relative to platinum.
