The Banco Argentino operated out of Rosario during a period when provincial and private banks in Argentina were largely free to issue their own currency — a situation that produced dozens of short-lived institutions before the 1890 crisis ultimately forced consolidation under the Banco de la Nación Argentina. Whether this particular bank survived long enough to see significant note circulation is uncertain; many of these provincial issuers folded within a few years of printing.

ABNC's involvement here is unsurprising — they dominated South American bank note contracts throughout the 1860s and 1870s, often supplying notes to institutions that never achieved meaningful scale.
