500 Australes

Jujuy's provincial emergency notes of 1989 were born out of Argentina's catastrophic hyperinflation crisis — by mid-year, annual inflation had surpassed 3,000%, and the national government was essentially unable to maintain adequate cash supply to the provinces. Several Argentine provinces issued their own quasi-currency that year, locally called "patacones" or simply "bonos," to cover payroll and basic transactions when federal banknotes ran dry.

The Austral itself was already a failed rescue — introduced in 1985 to replace the Peso Argentino at 1,000 to one, it lasted barely six years before being swept away by the Peso in 1992. A provincial 500 Austral note issued in 1989 was, by the time it reached circulation, worth almost nothing in real terms.
