Banco de Colombia was a private commercial bank chartered in 1875, operating during the period when Colombia's note-issuing privileges were distributed across competing regional banks rather than centralized under a single authority. The federal banking law of 1880 was actively reshaping that arrangement, and notes of this period exist in a compressed window between shifting regulatory regimes.

The American Bank Note Company held long-running contracts with numerous Colombian private banks simultaneously, which means the printing quality is high but the design language is shared across institutions — collectors should verify the issuing bank text carefully, as superficially similar ABNC-produced Colombian issues from this decade are frequently confused.
