20 Centavos Fuertes Banco Nacional del Paraguay

The Banco Nacional del Paraguay was a short-lived institution, established in 1886 and operating for only a few years before the country's banking sector collapsed into prolonged instability. This note belongs to its inaugural emission — the bank had barely opened when these were printed by the American Bank Note Company, whose contracts with South American republics in this period were nearly universal among newly chartered national banks seeking credibility through engraved security printing.

The denomination itself is telling. "Fuertes" distinguished these from older inflated peso emissions, signaling a hard-currency aspiration that Paraguayan monetary reality would struggle to support in the years following the catastrophic losses of the War of the Triple Alliance.
