2 1/2 Pesos

Colombia's 2½ Peso gold denomination was a direct product of the monetary reforms following the Thousand Days War, the brutal civil conflict that ended in 1902 and left the country's finances in ruins. The gold standard was formally restored under Law 33 of 1903, and the Bogotá mint resumed specie coinage tied to the French metric system — hence the .9167 fineness, aligned with Latin Monetary Union specifications Colombia never formally joined.

By 1913, output of this fractional gold denomination was already declining. The series would effectively cease with the First World War's disruption of gold coinage across Latin America.
