1 Nuevo Peso

Uruguay's 1976 coinage was issued under the civic-military dictatorship that had formally seized power in June of that year, dissolving parliament and suspending the constitution. The nuevo peso itself was introduced in 1975 as part of a currency reform that replaced the old peso at a rate of 1,000 to one — a direct response to inflation that had gutted purchasing power through the late 1960s and early 1970s.

The three-year run of this type ended as inflation continued to accelerate, eventually making the denomination effectively worthless by the early 1980s.
