1 Céntimo Countermark over Argentine Confederate 1 Centavo 1854

Paraguay in 1869 was a nation in ruins. The War of the Triple Alliance — fought against Brazil, Argentina, and Uruguay simultaneously — had by that point killed the majority of Paraguay's male population and left Francisco Solano López's government scraping for any functional currency it could find. Surplus Argentine copper centavos, themselves already fifteen years old, were countermarked and pressed into local circulation out of sheer necessity. The host coin, the Argentine Confederate 1 Centavo of 1854, predates Argentine national unification.

M#R19 is among the more elusive countermark types of this emergency issue.
