50 Pesos El Banco de Hidalgo

Banco de Hidalgo was one of the regional banks chartered under Mexico's 1897 Ley General de Instituciones de Crédito, which allowed individual states to issue their own currency — a system that produced dozens of distinct note-issuing banks operating simultaneously across the republic. Hidalgo's bank was headquartered in Pachuca, a silver-mining center, and its notes circulated primarily within state borders rather than nationally.

The American Bank Note Company held contracts with the majority of these Mexican state banks during this period, printing notes that were often structurally identical in design architecture but differentiated by color and text. The whole system collapsed when Carranza's revolutionary government abolished the old banking concessions in 1916 and demonetized the notes.
