Sonora's wartime currency program was one of the most administratively coherent of any Mexican state during the Revolution — a direct consequence of Governor Plutarco Elías Calles and the Constitutionalist faction's need to maintain a functioning economy in territory they controlled while Federal forces held the monetary infrastructure. The American Bank Note Company contract gave these issues a technical quality that most emergency state emissions of the period conspicuously lacked.

The S1076 sits at the high-denomination end of a series that saw rapid inflation erode its real value within months of printing. By late 1915, peso-denominated state notes across northern Mexico were being discounted heavily or refused outright as Carranza moved to consolidate monetary authority under the national government.
