5 Pesos El Estado de Sonora

Sonora was one of the few Mexican states with the economic and political coherence to issue its own paper currency during the Constitutional period of the Revolution. Governor José Maytorena authorized regional issues to pay troops and maintain commerce when federal Constitutionalist currency was either unavailable or distrusted locally — Sonora's notes circulated in parallel with, and sometimes in competition against, Carrancista paper.

American Bank Note Company's involvement was unusual for a revolutionary-period Mexican state issue; most emergency currency of 1913–1915 was printed domestically under rushed conditions. ABNC's engraved production gave Sonoran notes a visual credibility that helped acceptance in border trade with Arizona.
