The Banco Entre-Riano was a provincial bank operating out of Entre Ríos, one of the Argentine confederation's more turbulent provinces — still living in the long shadow of Justo José de Urquiza's dominance when this note was issued. Provincial banking in Argentina during the 1860s was a patchwork of competing local institutions, many of them undercapitalized and short-lived, issuing paper that circulated at steep discounts outside their home province.

The PS prefix in the Pick catalog places this firmly in the speculative or semi-official category. Whether this note saw meaningful redemption is doubtful; Entre Ríos provincial banking collapsed well before any national monetary framework could absorb these obligations.
