5 Pesos Bolivianos

The Banco Entre-Riano was a provincial bank operating out of Entre Ríos, Argentina, one of several short-lived regional institutions that briefly issued currency during the 1860s before the Argentine national government moved to consolidate monetary authority. Provincial bank notes of this period circulated under severe public skepticism — Entre Ríos had seen repeated monetary disruptions, and confidence in paper instruments issued outside Buenos Aires was chronically thin.

PS#1660A2 suggests a signature or series variant within the broader 1660 type. Provincial Argentine issues from this era are notoriously scarce in any form; the bank's operational lifespan was brief, redemption rates were low, and surviving paper is rarely documented outside a handful of specialist collections.
