50 Nuevos Pesos

Uruguay's shift to the "nuevos pesos" system in 1975 was a straight redenomination — one nuevo peso replacing 1,000 old pesos — aimed at simplifying accounting after years of inflation had made the old currency operationally unwieldy. The notes were not an emergency measure but a planned administrative reset, though inflation continued well past the reform.

Thomas De La Rue printed the series under the military government that had taken power in 1973. Pick 59 is the mid-denomination of the initial nuevos pesos release, a series that would itself be rendered obsolete when Uruguay was forced into a second redenomination in 1993.
