500 Pesos without 'Ley' or 'Decreto-Ley'

This denomination sits in the middle years of Argentina's military government, which took power in March 1976. The absence of any "Ley" or "Decreto-Ley" reference in the title reflects a deliberate shift in how the junta authorized its currency — earlier series had cited specific enabling legislation, a convention quietly dropped as the regime consolidated control and began governing almost entirely by decree without the formality of published legal instruments.

Inflation during this period was severe enough that 500 pesos, a meaningful sum when the series opened in 1977, had become effectively trivial by 1982. The note was superseded when Argentina redenominated at 10,000 to 1, introducing the Peso Argentino in June 1983.
