50 Pesos El Banco de Durango

El Banco de Durango was one of the regional banks authorized under Mexico's 1897 Ley General de Instituciones de Crédito, which formalized a system of state-chartered banks with note-issuing privileges — though the bank itself began operating before that legislation, under earlier concession arrangements. The American Bank Note Company in New York produced currency for dozens of Latin American institutions during this period, and the Durango plates show the same high-intaglio quality the firm applied across its commercial banking contracts.

The date range spans the Porfiriato's final years through the outbreak of the Revolution, meaning notes from this series were in circulation when Durango became a major theater of Villista and Maderista activity after 1910. By 1914, the regional banking system was effectively collapsing under wartime monetary chaos.
