1 Peso Oro Acuñado

The Banco de Bogotá was a private commercial bank, not a central issuing authority — Colombia's fragmented pre-1923 banking system permitted chartered private institutions to circulate their own paper, and the Banco de Bogotá was among the most prominent. The denomination itself, "Peso Oro Acuñado," is deliberately specific: it pegged redemption to coined gold, distinguishing these notes from the severely depreciated paper pesos that had flooded Colombia during the Thousand Days War and its aftermath.

ABNC printed extensively for Colombian private banks during this period. The 1923 Kemmerer Mission banking reforms, which established the Banco de la República as a central bank, effectively ended private note issue — rendering this series obsolete within a few years of printing.
