2 Pesos / 20 Reales Nueva Granada

Nueva Granada was already dissolving as a political entity when this note was printed — the Rionegro Constitution of 1863 would formally reconstitute the country as the United States of Colombia, making the issuing authority named on this note short-lived almost by design. The Tesorería General was issuing paper against a treasury perpetually strained by civil conflict, and the 1859–1862 civil war created the kind of fiscal pressure that forces governments to print.

Ayala i Medrano was one of the very few lithographic operations capable of producing official documents in Bogotá at mid-century. The dual denomination — Pesos alongside Reales — reflects the transitional monetary arithmetic of the period, when the decimal system had been adopted in principle but the old colonial real hadn't fully disappeared from public accounting.
