10 Pesos Plata Corriente Boliviana

The Banco de San Juan was one of several provincial Argentine banks authorized under the 1854 banking legislation that briefly allowed individual provinces to issue their own currency denominated in Bolivian silver — pesos plata corriente boliviana — rather than the depreciating Buenos Aires paper peso. The Tucumán branch issue is among the rarer provincial variants of this series, reflecting how thinly the San Juan bank's network actually operated in the interior.

Bolivian silver coinage was the dominant specie in the Argentine northwest throughout the mid-nineteenth century, making denomination in Bolivian units commercially practical in Tucumán in a way it would not have been on the coast.
