5 Pesos Red stamp 'TERCERA SÉRIE'

Paraguay's wartime government printed this note domestically during the War of the Triple Alliance — a conflict that by 1868 had already consumed a catastrophic share of the country's population and was nearing its ruinous conclusion. The "Tercera Série" red overprint distinguishes it from earlier emissions of nominally identical design, a crude but functional method of differentiating successive authorizations when engraving new plates was neither practical nor possible.

State-printed in Asunción under siege conditions, the paper quality and impression consistency vary considerably across surviving examples. The watermark — unusual for a domestic wartime issue — was likely inherited from imported paper stock rather than purpose-designed security printing.
