50 Nouveaux Francs / 5000 Francs

The Institut d'Émission des Départements d'Outre-Mer was created in 1959 specifically to manage currency in France's overseas departments — Martinique, Guadeloupe, Réunion, and French Guiana — following the constitutional reorganization that formally integrated these territories into the French Republic. This note bridges two monetary systems: the dual denomination reflects the conversion from old to new francs introduced by de Gaulle's 1960 redenomination, where 100 old francs became 1 nouveau franc, making the 5000/50 pairing mathematically exact rather than approximate.

Printed by the Banque de France's own workshops, the series was never issued through a colonial central bank but directly through a Paris-administered body with no local printing capacity of its own.
