1 Real Plata Boliviana

El Banco Argentino de Santa Fe was one of the provincial banks that briefly flourished under Argentina's 1872 banking law, which allowed individual provinces to charter note-issuing institutions before the national government eventually consolidated that authority. The denomination in reales plata boliviana rather than pesos is telling — Bolivia's silver coinage still circulated widely in the interior provinces, and Santa Fe's commercial ties ran more toward the Littoral trade routes than toward Buenos Aires.

The ABNC plate was almost certainly a shared or adapted design; the company routinely supplied multiple Argentine provincial banks from its New York workshop during this period, which sometimes makes attribution tricky without the printed bank name as a guide.
