Banco de Medellín was one of several private Colombian banks authorized to issue currency under the banking law of 1880, which permitted departmental banks to circulate notes freely — a system that lasted until the government moved to consolidate monetary control in the early twentieth century. The 1899 date places this note squarely within the Thousand Days War, the devastating civil conflict between Liberal and Conservative factions that ran from 1899 to 1902 and severely disrupted banking operations across Antioquia.

Private bank issues from this period are genuinely scarce; many Colombian departmental banks collapsed or ceased operations during the war, and surviving note stocks were not preserved systematically.
