Banco Occidental was one of several regional Colombian banks operating under the 1880 banking legislation that briefly allowed private institutions to issue their own currency. The New York-printed plates from the American Bank Note Company were standard practice for Colombian private banks of this period — ABNC supplied engraved work to a dozen or more such institutions simultaneously, which means the printing quality on this note is considerably higher than the issuing bank's actual financial standing might suggest.

The series span of 1893–1917 is unusually long. Most Colombian private banks were forced to surrender their note-issuing privileges after the Reyes administration centralized monetary control around 1905, so any dates after that point warrant scrutiny — late-dated examples may reflect authorized holdover circulation rather than fresh issue.
