10 Soles Compañia de Obras Públicas y Fomento del Perú

The Compañía de Obras Públicas y Fomento del Perú was a private infrastructure concessionaire, not a bank — its note-issuing authority derived from concession arrangements with the Peruvian government during the guano-boom years, when Lima was financing public works through a tangle of private contracts rather than direct state spending. By 1876, that boom had already collapsed, and Peru was sliding toward the fiscal crisis that would deepen into the catastrophic borrowing defaults of the late 1870s.

The National Bank Note Company's listed operational dates end in 1872, yet this note is dated 1876 — almost certainly printed from plates produced earlier and held in inventory, a common arrangement with American security printers of that period.
