50 Australes

Tucumán's 1991 austral notes were provincial emergency currency, issued during the acute fiscal crisis that pushed several Argentine provinces to print their own quasi-money when transfers from the federal government collapsed. These circulated alongside national australes as de facto legal tender within the province — a workaround that was legally ambiguous but practically unavoidable.

The austral itself was already a dying currency by 1991; Convertibility and the peso replaced it the following year. Provincial paper issued in the final stretch of that monetary chaos has always been difficult to attribute precisely, and the PS catalog reference reflects its quasi-banking status rather than any formal central bank authorization.
