1.000 Pesos Oro

The 1,000 Pesos Oro was produced entirely in-house at the Banco de la República's own printing facility in Bogotá — one of the few Latin American central banks with that capability at the time. The note was issued across a period of significant monetary pressure in Colombia, with inflation running above 25% annually through much of the late 1980s, which compressed the denomination's purchasing power considerably during its relatively short circulation window.

Three distinct signature combinations across four years reflect genuine administrative turnover at the bank, not reprints or replacement issues. The 1991 pairing of Urrutia Montoya and Clavijo Vergara marks a transition period before the denomination was effectively superseded by higher values as inflation continued.
