50 Pesos

Banco de Londres y Río de la Plata was a British-founded institution established in Buenos Aires in 1862, and its Córdoba branch operated with a degree of regional autonomy that extended to issuing its own notes — a common arrangement under Argentina's pre-federal banking regime. The PS prefix in the Pick numbering places this firmly in the "Specialized" category of provincial and private issues, which in Argentina's case covers the chaotic decade before the Banco Nacional was established in 1872.

By 1869, Córdoba's economy was still heavily tied to cattle and mule trade rather than export agriculture, and a 50 Peso denomination would have been a substantial instrument — not everyday commerce, but interbank settlement or large merchant transactions.
