1 Pesos La Tesorería de la Federación, Guaymas

Guaymas, Sonora was a federal stronghold during the Revolution's most fractured phase, and the Tesorería de la Federación issued these notes as Huerta's government scrambled to maintain financial control over the northwest while competing currencies — Villista, Constitucionalista, local emergency emissions — flooded the same territory. The Mazatlán firm of A. Díaz de León e Hijos was one of the few commercial lithographers in the region capable of producing passable security printing on short notice.

By late 1914, Huerta had fled the country and most federalist emissions from this period were repudiated outright. Sonoran circulation was brief and chaotic.
