50 000 Australes - Provisional Issue

Argentina's hyperinflation crisis of 1989 rendered existing denominations obsolete faster than new notes could be designed and printed. The provisional solution was straightforward: overstamp existing 5 Australes notes with a new value, effectively multiplying the face denomination by 10,000. That ratio alone tells you something about the speed of monetary collapse that year, when annual inflation exceeded 3,000 percent.

The overprint was applied by Casa de Moneda in Buenos Aires — the same facility that had printed the underlying note — which at least ensured some consistency in paper and security feature alignment. Collectors should check overprint registration carefully; misaligned applications are known within the series.
