Watch List notes:

Colombia (struck at the Heaton mint, Birmingham, England), silver proof pattern 20 centavos, 1900, very rare, NGC PF 62, finest and only example in NGC census. Restrepo-78 (p. 254); KM-Pn81. Lustrous mirror fields but with raised rims and bolder details as more properly a specimen strike (therefore superior to the Eldorado example), with light golden toning, no wear but incidental marks under chin. NGC #4668518-004.
