10 Francs Dolphins

Burundi has no coastline, no dolphins, and no historical connection to the animal depicted — a detail that places this squarely within the modern bullion and novelty collector market, where sovereign minting rights are licensed to private distributors producing themed issues for foreign sale. The Banque de la République du Burundi has issued dozens of such pieces since the 2010s, few of which ever enter Burundian commerce.
