Banco de Occidente was one of several Colombian regional banks that issued their own currency under the banking freedom law of 1880, which briefly allowed private and regional banks to print notes backed by their own reserves. The arrangement collapsed when the government of Rafael Reyes nationalized monetary emission in the early 1900s, leaving many outstanding regional notes in legal limbo and ultimately unredeemed — which accounts for the relatively wide date range attributed to this series.

ABNC printed extensively for Colombian regional issuers during this period, and the plates were often held in New York for reuse across multiple print runs, sometimes spanning decades.
