10 Francs Atum

The "Atum" designation places this piece within Burundi's ongoing bullion and collector series drawing on ancient Egyptian iconography — an unusual thematic choice for a landlocked Central African nation with no historical connection to the Nile Valley. These issues are produced for the international collector market, not domestic circulation, and Burundi has leveraged its mint licensing agreements to release dozens of such thematically eclectic gold pieces since the 2010s.

At 0.311 g of .9999 gold, this is fractional bullion at its smallest practical extreme — roughly one-hundredth of a troy ounce.
