The Banco Nacional de Chile was a private commercial bank, not a state institution — Chile's chaotic banking law of 1860 had opened the door to a proliferation of private note-issuing banks, and by the 1870s dozens of them were competing for circulation across the country. The Banco Nacional was among the larger and more stable of these, though the financial turbulence preceding and during the War of the Pacific would eventually reshape the entire Chilean banking sector.

ABNC produced several series for Chilean private banks during this period, often sharing decorative plate elements across different clients — worth checking against other South American issues from the same years if examining plate provenance.
