1 Peso Oro Acuñado

The Banco de Bogotá was a private commercial bank, not a central issuing authority, and its notes circulated alongside those of several competing private banks in Colombia well before the Banco de la República was established in 1923 to consolidate the country's monetary framework. ABNC handled the printing for much of Colombian private banking at this period, supplying engraved notes that carried more visual authority than the issuing institutions sometimes warranted.

The denomination — "Peso Oro Acuñado," meaning minted gold peso — is the telling detail. The qualifier distinguished these notes from debased or depreciated peso variants and was a direct response to chronic monetary instability following the Thousand Days War and the inflationary paper emissions that scarred public confidence in Colombian currency for decades afterward.
