4 Reales Plata Boliviana

Banco Argentino operated out of Córdoba during a brief window when Argentina's provincial banking system was still largely unregulated — before the national government moved to consolidate currency authority in the 1880s. The denomination itself, reales plata boliviana, reflects the commercial reality of the interior provinces, where Bolivian silver coinage circulated more reliably than anything Buenos Aires could guarantee. Quoting a denomination in a foreign silver standard was a practical hedge, not an eccentricity.

The ABNC contract for this series is early for an Argentine provincial client — 1873 predates the company's heaviest South American workload by nearly a decade.
