1000 Pesos Oro

The 1000 Pesos Oro ran for over a decade under P#424, spanning a period when Colombia's central bank was under extraordinary pressure from narco-dollar inflows that made routine monetary management almost meaningless. The denomination itself was being eroded steadily by inflation — by 1993, 1000 pesos bought a fraction of what it had in 1982, which partly explains why the series was eventually superseded by higher denominations printed in much larger volumes.

Production was split between De La Rue in London and the Banco de la República's own Imprenta de Billetes in Bogotá, so plate consistency across the run is worth examining closely before attributing a specific example to either source.
