1000 Pesos

Colombia's central bank has operated its own intaglio printing facility in Bogotá since 1959, one of relatively few Latin American institutions to maintain full in-house production rather than contracting to European or North American security printers. The 1000 Pesos P#450 series came out of that facility across a four-year run, with annual date variants that collectors treat as distinct collectibles despite identical designs.

Security architecture on this series is modest by contemporary standards — watermark and thread only, with no optically variable ink or microprinting — reflecting the note's low purchasing power by the early 2000s, when Colombian inflation had long eroded the 1000 Peso denomination toward everyday transactional use rather than any significant store of value.
