500 Pesos Fuertes Administración de la Deuda Pública

Paraguay's public finances in 1899 were still deeply compromised by the catastrophic losses of the War of the Triple Alliance, which had ended thirty years earlier but left the country dependent on foreign loans and chronically short of hard currency. The Administración de la Deuda Pública was not a conventional bank of issue — it was essentially a debt-management body empowered to emit paper as a function of servicing and consolidating national obligations rather than supporting ordinary commerce.

The American Bank Note Company engraved and printed the series in New York. At 500 Pesos Fuertes, this is the highest denomination in P#100–104 range, and high-denomination notes from this issuer circulated narrowly if at all — most purchasing power in rural Paraguay at the time operated well below this level.
