Banco del Estado was one of several Colombian departmental banks operating under the 1880 banking law that permitted individual states to charter note-issuing institutions. Cali's bank served the Cauca region, a coffee-producing corridor increasingly integrated into export markets by the turn of the century — which is precisely when this note appeared. The timing matters: 1900 falls squarely within the Thousand Days War, the devastating civil conflict that wrecked Colombia's monetary system and drove most private bank notes to near-worthlessness through hoarding, repudiation, and forced conversion.

Few Banco del Estado issues survived that period in collectible numbers.
