10 Australes

Tucumán's austral notes were provincial emergency currency, issued during the collapse of the national austral and the broader fiscal crisis that preceded Argentina's hyperinflationary peak. The provinces had no legal authority to print money but did so anyway — Tucumán among several that issued quasi-money known as "bonos" or "bocades" to pay provincial employees and suppliers when federal transfers dried up. These circulated at par with the national currency in theory, and at a significant discount in practice.

Casa de Moneda printed these under contract, which gave them a veneer of official legitimacy that purely locally-printed provincial notes lacked. Within two years, convertibility and peso replacement had rendered the entire austral series obsolete.
