5 Pesos El Estado de Sonora

Sonora's 1913 state issues emerged from a direct confrontation between Governor Maytorena and the federal center — after Victoriano Huerta's coup, Sonora refused to recognize the new government and effectively functioned as a breakaway administration, printing its own currency to meet payroll and maintain the anti-Huerta resistance. Maytorena's own signature on these notes was not ceremonial; he was the political architect of Sonora's defiance.

Juan Sánchez Azcona, the co-signer, was a journalist and Maderista loyalist who served as Maytorena's secretary of government — an unusual choice for a signatory, reflecting how improvised the administration's financial apparatus genuinely was. The Imprenta del Estado had no specialized banknote equipment, and that shows in the printing quality.
