1000 Pesos with 'DECRETO-LEY' on Obverse

Argentina's chronic inflation through the early 1970s meant that a 1000 Peso note — once a significant denomination — was losing purchasing power almost faster than the presses could keep up. The "DECRETO-LEY" overprint reflects the legal framework under which this series was authorized: a legislative decree rather than a formal congressional act, a distinction that mattered during a period when Argentina cycled through civilian and military governments with unsettling regularity.

Casa de Moneda printed the entire run domestically. The series straddles the return of Perón in 1973, his death in 1974, and the military coup of March 1976 — a span of three years that encompassed three different heads of state and accelerating monetary disorder that would eventually necessitate the 1983 Peso Argentino reform.
