1 Peso Oro

Colombia's 1 Peso Oro notes of this period were among the last of the denomination to be printed abroad before the Banco de la República shifted lower-value production to the Casa de Moneda in Bogotá. Waterlow & Sons had handled Colombian contracts intermittently since the early twentieth century, and their work on this series is competent if unshowy — the firm was in commercial decline by the early 1950s and would be absorbed following the Waterlow affair's long reputational tail.

The single watermark is the note's only security element, modest even by contemporary standards for a circulating peso note.
