COLOMBIA. 1873 pattern Peso. Medellín mint. Restrepo P54. Silver. SP-63 (PCGS).Plain edge. Dark gray obverse fields and devices yield to slightly lighter peripheries, while the reverse is a blend of gray, gold, blue, and sea green. Boldly defined and beautifully preserved, magnified scrutiny finds only trivial hairlines. A superb Peso essai with abundant visual appeal.
