1 Real Boliviano

The Caja de Ahorros of Rosario was one of several provincial savings institutions that briefly entered note issuance during the 1860s and 1870s, a period when Argentina's monetary supply was chronically fragmented — each province effectively managing its own paper credit. The Real Boliviano as a unit of account was already anachronistic by 1870, a holdover from colonial-era reckoning still in informal use across the interior long after the peso had nominally taken over.

Lit. Carlos Held was a German-Argentine lithographic firm operating in Rosario, better known for commercial printing than banknote production. The note's local manufacture rather than importation from an established security printer in Europe or the United States puts it at the modest end of Argentine provincial issues.
