2 Reales Bolivianos

The Banco Entre-Riano was a provincial Argentine bank operating in Entre Ríos province, and its 1866 issues denominated in reales bolivianos reflect a genuinely complicated monetary situation: the province was using a foreign currency unit — the Bolivian real — as its reference standard at a time when Argentina had no unified national currency. The Confederation had collapsed, Buenos Aires had only recently reintegrated, and provincial banks were issuing their own paper largely unchecked by any central authority.

Specimens and remainders from Entre-Riano are exceedingly rare in any form. The bank's operational lifespan was brief, and documented circulation of its notes is poorly attested in Argentine monetary records.
