50 Centavos

Mouchon was a French engraver best known for designing postage stamps — his work on Argentine banknotes was essentially a job-for-hire through the Buenos Aires printing establishment, and his name appearing on small-denomination notes like this one is more a reflection of Argentina's interwar reliance on European design talent than any particular prestige commission.

The 1948–1950 dating spans the early Perón years, when the nationalization of the Banco Central in 1946 had already reoriented it as an instrument of state economic policy rather than an independent institution. A 50 centavos note in this period was genuinely useful tender — inflation had not yet eroded small denominations into irrelevance, though that would come.
