5 Pesos Oro

Colombia's Banco de la República was established in 1923 under Law 25, part of a sweeping monetary reform engineered with the direct involvement of the Kemmerer Mission — a team of American financial advisors led by Princeton economist Edwin Kemmerer who restructured the central banking systems of multiple Latin American nations during the 1920s. This note is among the earliest issues of that new institution, printed by ABNC almost certainly as part of the founding order placed that same year.

The "Pesos Oro" denomination was a deliberate signal — Colombia had endured decades of monetary chaos following the Thousand Days War, including a hyperinflationary collapse of the old paper peso. The gold-backed designation was meant to restore credibility as much as to describe actual convertibility.
