| 表面の説明 | Intaglio portrait of Camilo Torres Tenorio in three-quarter view occupies the right portion of the note, identified by the caption CAMILO TORRES at lower right. The centre carries the large numeral 50 over the legend PAGARA AL PORTADOR / CINCUENTA PESOS ORO, set against a delicate guilloche underprint with a pre-Columbian gold artefact vignette at lower left. The ornate dark-purple lathe-work border frames all four sides, with denomination numerals repeated in the corners. |

Colombia's Banco de la República began producing its own notes domestically in earnest from the late 1970s onward, having previously relied on foreign security printers. The Imprenta de Billetes — the bank's own printing plant in Bogotá — took on this series, and the results show the transition: quality is competent but uneven across the run, and paper consistency varies noticeably between 1984 and 1986 printings.
The sole security feature is a watermark, modest even by the standards of the period. Within two years of this series closing, Colombia had moved to significantly more sophisticated anti-counterfeiting measures driven by the narco-dollar inflation pressures of the late 1980s.
