1000 Francs

The Banque de l'Algérie operated under a renewable concession from the French state, and the 1,000 Franc denomination was essentially an instrument of the settler economy — too large for most Algerian daily commerce and oriented toward the European mercantile class running trade between Algiers and Marseille. The plates were executed by Robert and Wullschleger at the Banque de France's printing works, the same atelier responsible for metropolitan French issues of the period, which explains the visual continuity with Paris-issued notes.

The 21-year span of this issue across three distinct signature combinations reflects just how stable — or static — colonial monetary administration was. The 1918 date falls mid-war, when the Algerian economy was under considerable strain from wartime requisitions and labor mobilization.
