10 Pesos Oro

Colombia's monetary situation in 1915 was still recovering from the catastrophic paper money inflation of the Thousand Days' War period (1899–1902), during which the government had issued billions of pesos in unbacked paper. The shift to "Pesos Oro" — gold pesos — in the denomination name was a deliberate signal of convertibility and fiscal discipline, even when the notes themselves were still paper instruments.

The American Bank Note Company contract reflects Colombia's preference at the time for foreign security printers over domestic production, a practical necessity given the country's limited intaglio infrastructure. ABNC had printed Colombian issues for decades by this point.
