1000 Francs

The Banque de l'Algérie was established in 1851 as a colonial issuing authority, modeled loosely on the Banque de France but with tighter government oversight reflecting Paris's ambivalence about granting full monetary autonomy to a settler colony. This 1000 Francs denomination sat at the top of the circulation hierarchy and would have moved almost exclusively through commercial and government transactions — retail use at that level was effectively nonexistent in late 19th-century Algeria.

Cabasson's involvement places this firmly within the French academic engraving tradition of the period. The long issuance window — nearly three decades — means individual notes can vary in hand-completed date details, and serial numbering practices shifted across the run.
