100 Pesos

Mouchon's name on Argentine banknotes is something of a red flag for assumptions: the French engraver died in 1914, meaning his credit here reflects an earlier plate design recycled by the printer, almost certainly the American Bank Note Company, which held long-standing contracts with Buenos Aires through this period. The design predates the note's issue by decades.

The 1936–1943 date range spans Argentina's infamous "Década Infame" — a period of fraudulent elections and political instability that nonetheless saw the Banco Central, founded only in 1935, consolidating its monopoly over currency issue for the first time. This 100 Pesos denomination circulated alongside notes still issued by provincial banks during the transition.
