100 Pesos with 'DECRETO-LEY' on Obverse

Argentina's monetary situation in the mid-1970s was deteriorating fast enough that the Banco Central issued notes with "DECRETO-LEY" printed directly on the face — an explicit acknowledgment that the emission authority derived from decree-law rather than an act of a functioning legislature. It is an unusual admission to put on circulating currency, and it dates the note squarely to the period of institutional instability preceding the March 1976 coup.

Pick 297 was produced by the Casa de Moneda in Buenos Aires throughout a period of triple-digit inflation, which means high-grade survivors are genuinely uncommon — not because the notes were rare, but because they moved quickly and were spent hard.
