100 000 Cordobas overprinted on 500 Cordobas

Nicaragua's inflation in the late 1980s was severe enough that the Banco Central resorted to overprinting existing stock rather than commissioning entirely new designs — a stopgap that compressed two separate denominations into a single physical object. The 500 Córdobas note was already in circulation when the overprint was applied, making P#149 a direct paper record of monetary collapse in real time.

Thomas De La Rue handled both the original printing and the overprint work, which kept the security continuity intact but did nothing to slow the underlying devaluation. Nicaragua would replace the entire Córdoba with the Gold Córdoba at a rate of 1:5,000,000,000 in 1990.
