2 Francs

Struck in the Belgian Congo rather than occupied Belgium, this issue dates to the period when the colonial administration — operating from Léopoldville under Free Belgian authority — needed to maintain a functioning currency entirely independent of the Nazi-controlled metropole. Brass was a deliberate wartime substitution; the Congo's own mineral wealth, including copper from Katanga, made local production feasible when transatlantic supply chains were anything but reliable.

The mint of origin for this series was Pretoria, South Africa — a detail that underscores just how thoroughly the war had reorganized where and how colonial currencies were actually made.
