20 Pesos Bolivianos

Banco Paraná was one of several short-lived provincial Argentine banks that obtained note-issuing authority during the fractured monetary period following the fall of Rosas. Its 20 Pesos Bolivianos denomination was calibrated to the Bolivian silver peso, which remained in wide commercial use across the Litoral provinces long after Buenos Aires had moved toward its own currency conventions — a practical concession to cross-border trade on the Paraná river corridor.

The American Bank Note Company contract places this squarely in the era when Argentine provincial banks almost universally turned to New York engravers, lacking any domestic security printing infrastructure. ABNC's production records from this period show plates were often shared or adapted across multiple South American clients, so close inspection of the vignette borders against contemporaneous issues from other ABNC-printed Argentine provincials can be worthwhile.

PS#1819 is genuinely scarce. Banco Paraná had a short operational life, and surviving issued examples are rarely encountered.
