1000 Nuevos Pesos

Uruguay's 1000 Nuevos Pesos series was issued during the military dictatorship that had suspended civilian government in 1973. The "Nuevos Pesos" denomination system had been introduced in 1975, replacing the old peso at a rate of 1000 to 1 — meaning this note's face value was already, nominally, one billion old pesos. Inflation through the late 1970s continued to erode it further.

Thomas De La Rue's involvement was routine for the region and period; the Uruguayan central bank relied on the London printer for much of its high-denomination output during these years. The watermark remains the sole listed security feature, which was not unusual for the series but left it vulnerable to the crude local counterfeiting that plagued several Southern Cone currencies in this period.
