100 Pesos Oro

The Banco de la República has printed its own notes in-house since 1959, one of the few central banks in Latin America to do so continuously. This note falls within a long run of domestic production at the bank's Bogotá facility — the same plant that also handled stamps and official documents — which gave the institution unusually tight control over security specifications, though the range of watermark complexity across the series reflects iterative improvements rather than a single fixed standard.

The "Pesos Oro" denomination designation, linking the unit nominally to gold, was already an anachronism by the 1980s. Colombia formally dropped the term when the peso was redenominated in 1993.
