100 Pesos Overprint on 10 000 Pesos

Argentina's chronic inflation of the 1960s periodically forced the Banco Central into stopgap measures rather than full reissues. This note is a 10,000 Pesos note of the 1961–69 series overprinted and revalued downward to 100 Pesos following the monetary reform of January 1970, when the peso moneda nacional was replaced by the peso ley 18.188 at a rate of 100 to 1. The overprint was a practical bridge while new stock was prepared.

The conversion ratio means the underlying note's face value collapsed by a factor of 100 overnight — a detail the overprint makes visible in an unusually literal way.
