10 Pesos Fuertes

The Banco de la Província de Buenos Aires was one of the few provincial institutions that maintained genuine credibility during Argentina's chaotic mid-19th-century banking period. By 1869 it had already survived two major liquidity crises — 1857 and 1866 — and continued issuing notes largely because the national government lacked the infrastructure to impose a unified currency. The "Pesos Fuertes" denomination was the province's own accounting unit, pegged notionally to silver but increasingly nominal in practice.

The American Bank Note Company's New York workshops handled the engraving and printing, a relationship Buenos Aires maintained for decades. ABNCo's security printing was considered difficult to replicate locally, which mattered in a market where counterfeiting provincial notes was not uncommon.
