10 Pesos Fuertes

The Banco Comercial de Santa Fé was one of several provincial institutions operating under Argentina's pre-1890 decentralized banking regime, when individual provinces retained the authority to charter note-issuing banks largely free from federal oversight. Santa Fé's commercial banking sector in this period was closely tied to the colony boom — Swiss, Italian, and French agricultural settlements were being established across the province through the 1860s, and circulating paper money from local institutions filled a genuine transactional gap in those communities.

The "Pesos Fuertes" denomination was a hard-currency accounting unit, nominally tied to silver, though convertibility in practice depended entirely on the issuing bank's reserves at any given moment. By the early 1870s that distinction had become largely theoretical for most provincial issuers.
