Colombia's Tesorería General — the national treasury, not the central bank — issued paper currency during periods when the Banco de la República either did not yet exist or lacked the infrastructure to supply the market. This note predates the founding of the Banco de la República by three years; the 1923 Kemmerer Mission reforms that created it were still a political negotiation away.

The American Bank Note Company contract for Colombian treasury notes during this period involved plates shared or adapted across multiple denominations and years, which occasionally produced minor typographical inconsistencies between print runs. Worth examining the serial prefix carefully against documented series ranges.
