1 Peso Overprint on 100 Pesos

Argentina's chronic inflation made large denominations obsolete faster than new notes could be printed. Rather than wait for fresh stock, the Banco Central authorized a provisional overprint reducing the face value of existing 100 Peso notes to 1 Peso — a ratio that tells you everything about what had happened to purchasing power in the preceding decade. The overprint program ran from 1969 through 1971, bridging the gap until purpose-designed low-denomination notes could enter circulation.

Chalcographic printing on the base note indicates intaglio production, giving the paper a tactile quality that the overprint itself — applied separately — does not share.
