COLOMBIA. Banco de la República de Colombia. 20 Pesos Oro. July 20, 1927. P-378sp. Specimen.A gorgeous Specimen note. All three TDL 1927 denominations are tough types in Specimen or issued form. Violet face printing with portrait of Caldas left. Red zero serial numbers, though not stamped “SPECIMEN” on the face. Referred to as “Specimen Proof” by PMG and similar to lot 10048 in Eldorado 1 which realized $960 in January 2018. This is fully Uncirculated with bold colors. Worthy of an equally strong or better result.
