1000 Francs CFA Tsiolkovsky Sputnik

Benin's franc CFA coinage has no practical monetary function at this weight and fineness — these are collector issues produced under licensing arrangements that have nothing to do with the issuing nation's history or economy. This piece commemorates Konstantin Tsiolkovsky, the Russian rocket theorist who died in 1935, and Sputnik, launched by the Soviet Union in 1957. The pairing is historically coherent: Tsiolkovsky's theoretical work on multistage rockets and liquid propellants directly underpinned the Soviet space program that produced Sputnik.
