Banco de Tacna occupied one of the stranger corners of Peruvian provincial banking. Tacna itself was under Chilean occupation from 1880 following the War of the Pacific, and remained so until 1929 — meaning this note was issued by a Peruvian institution operating in territory that was, for decades, administered by a foreign power. Whether these notes circulated freely alongside Chilean currency, or were suppressed, is a question the surviving examples quietly pose.

The ABNC printing is unsurprising for the region and period; most South American provincial banks of the era contracted New York or London houses rather than local printers.
