1 Peso / 10 Reales Nueva Granada

Nueva Granada's short-lived federal experiment produced this note at a peculiar administrative moment — the country was in the process of reorganizing itself into the Confederación Granadina and then the Estados Unidos de Colombia, meaning the issuing authority named on this note effectively ceased to exist within months of printing. The dual denomination, one peso rendered also as ten reales, reflects the coexistence of the old Spanish colonial reales system with the incoming decimalized peso, a transition that was legally mandated but practically messy in the early 1860s.
