10 Pesos Fuertes

The Banco de San Juan operated as one of Argentina's provincial banking institutions during the mid-nineteenth century, a period when individual provinces issued their own currency with minimal federal oversight. A branch in Tucumán issuing notes denominated in pesos fuertes — the hard peso standard tied nominally to silver — reflects the commercial reach these provincial banks attempted across interior Argentina before the monetary consolidation efforts of the 1880s brought most of them to an end.

The PS prefix in the Pick catalog places this among Argentine provincial and private issues, a category where surviving examples are genuinely uncommon. Documentation on this specific branch's circulation history is sparse.
