COLOMBIA. 1875-B 50 Centavos. Bogotá mint. Restrepo 308.2. MS-63 (PCGS).A superlative example of this type, with exemplary toning over frosty surfaces. Full luster is seen on both sides, and the details are soundly struck throughout. Aside from a splash of deeper color in the upper left obverse, the toning shows an even opalescence. Some natural granularity is seen at the central obverse, but this remains among the finest seen of this design type.
