10 Pesos Moneda Boliviana

Banco Entre-Riano was a provincial Argentine bank operating out of Entre Ríos province, and like most of its contemporaries in the 1860s–70s, it contracted its note printing abroad rather than domestically. The Compañía Nacional de Billetes de Banco — the National Bank Note Company of New York — handled a substantial share of Latin American provincial paper during this period, producing notes for issuers who lacked local printing infrastructure of any consequence.

The denomination in "Pesos Moneda Boliviana" is the telling detail here. Bolivia's peso fuerte circulated as a de facto trade currency across the Río de la Plata region, and Entre Ríos banks denominated notes in it specifically for cross-border commerce rather than domestic retail use. The PS prefix in the Pick catalogue confirms provincial or private status — not a national issue.
