During the First World War, Belgium faced a serious shortage of small change. The Société Générale de Belgique then decides to put into circulation a series of 6 notes of 1, 2, 5, 20, 100 and 1000 francs. Over 100,000,000 copies will be issued for the 1 franc, 23,900,000 copies for the 2 francs, 17,862,000 copies for the 5 francs, 9,744,000 copies for the 20 francs, 13,425,000 copies for the 100 francs and 404,000 copies for the 1000 francs. The three largest values are difficult to find today. The armistice ending hostilities of the First World War was signed on November 11, 1918. On November 20, Société Générale de Belgique was completely dismantled and the National Bank of Belgium definitively resumed its status as an exclusive issuer of banknotes.
