COLOMBIA. 1873-B 50 Centavos. Bogotá mint. Restrepo 306.2. UNC Detail, Cleaned (PCGS).A very high grade example, with light golden toning and superb cartwheel luster over frosty surfaces. Some trivial hairlines explain the grade descriptor, but the eye appeal remains exemplary. Rarely encountered better than EF and perhaps unknown finer than seen here.
