1/2 Real Boliviano

Banco Rio Cuarto was a provincial Argentine institution operating out of Córdoba province during the brief free-banking period of the 1870s, when the national government had not yet established firm control over note issuance. The denomination itself — half a Real Boliviano — reflects the monetary chaos of the period: Argentine commerce still ran heavily on Bolivian silver reales alongside the peso, and banks in the interior simply denominated paper accordingly.

The National Bank Note Company, at the time one of the dominant security printers in the Americas, produced notes for dozens of South American institutions during this decade. Many of these provincial Argentine issues survived in tiny quantities; several banks collapsed or were absorbed before their notes saw meaningful circulation.
