100 Francs

The Banque d'Emission du Rwanda et du Burundi was a short-lived transitional institution, created in 1960 to manage currency for what were still UN Trust Territories under Belgian administration. It ceased operations when both Rwanda and Burundi became independent in 1962 and established their own central banks — making the entire series issued under this authority one of the briefest sovereign-adjacent monetary runs in post-colonial African history.

Thomas De La Rue's involvement was typical of the period, as Belgian colonial authorities routinely contracted London security printers for their African territories. The series was replaced almost immediately, and notes returned in relatively large quantities during the 1962 currency conversion, which dampens scarcity in higher grades.
