5 Pesos Oro

Colombia's Banco de la República was only four years old when this note entered circulation, established in 1923 under the recommendations of the Kemmerer Mission — the American financial advisory team that restructured monetary systems across several Latin American countries during the 1920s. The bank's early note contracts went almost exclusively to the American Bank Note Company, a natural consequence of U.S. financial influence over the reform process itself.

The Pesos Oro designation was deliberate, anchoring the currency nominally to gold at a fixed rate — a commitment that held until the pressures of the early 1930s depression forced suspension of convertibility in 1931.
