Banco Crédito Unido was a short-lived Colombian private bank operating under the 1870s free banking legislation that briefly allowed chartered institutions to issue their own currency. The American Bank Note Company produced notes for dozens of Latin American clients during this period, and the quality of engraving on these Colombian commissions was markedly higher than what local printing could have delivered.

The bank itself collapsed well before the 1886 constitutional reforms that eventually centralized Colombian note issuance under the Banco Nacional, meaning this note's circulation window was narrow. Surviving examples from Crédito Unido are genuinely uncommon across all denominations.
