COLOMBIA. 1873 pattern Decimo. Medellín mint. Restrepo P38. Silver. SP-65 (PCGS).Reeded edge. The uniface obverse form of this essai, with a totally blank reverse. Boldly reflective and nearly fully brilliant, bright and untoned but for some very subtle toning that gathers around design elements. A very impressive piece, showing bold cameo contrast between the portrait and the mirrored fields. Easily deserving of its assigned grade.From Christies, January 1974.
