1873, "Medellín mint", similar but struck with dies by L.C. Wyon, 26.6 grms. (Fr.158; KM.158; Restrepo, Y41.337.7), possibly a Proof produced in England, or with English dies, that escaped into circulation, certainly the protected areas of the fields are deeply mirrorlike and the rims are sharp, extremely fine overall
