500 Australes

Tucumán's 1989 austral emergency notes were issued under the *Bono de Cancelación de Deudas* program — a provincial quasi-currency scheme forced on several Argentine provinces when hyperinflation made the national austral effectively unmanageable for local government payrolls and suppliers. Tucumán was among the most aggressive issuers, circulating these bonds as de facto cash when the federal treasury couldn't keep pace with demand.

The broader collapse that year saw national inflation exceed 3,000 percent, which is why provincial paper from this period often shows heavy handling damage — these notes moved fast and were discarded once federal stabilization resumed.
