50 Pesos

The Banco Nacional de los Estados Unidos de Colombia was the country's first government-owned bank, established in 1880 under the Núñez administration as part of a broader effort to centralize monetary control away from the proliferating private state banks that had operated since the 1860s. American Bank Note Company secured the printing contract — their standard arrangement for much of Latin America at this period — producing a series that included this 50 Pesos denomination.

The bank's lifespan was short and contentious. It was liquidated in 1894 after chronic over-issuance eroded public confidence, and the notes were eventually demonetized. High-denomination survivors from the 1881 series are genuinely uncommon as a result.
