Watch List notes:

Pair of gilt-bronze uniface proof patterns (obverse and reverse essais) for Medellin, Colombia, gold 10 pesos, 1873, engraver A. Barre (Paris), nine five-point stars, reeded edges, very rare, NGC PF 65 Cameo and PF 64 Cameo (both in one slab).Restrepo-63 (p. 207); Sed-p. 47; KM-TS9, TS10.15.63 grams total; 26mm each; slab 4-3/8" x 3-7/8".Brightly lustrous and choice, neither with any marks but both with traces of light oxidation and verdigris, actually a perfectly matched pair despite the dissimilar grades. Like the 20 pesos patterns in the previous lot (same design), the 10 pesos were struck in several different forms, including a regular issue (unlike the 20 pesos), not to be confused with a concurrent design by Wyon in London.Pedigreed to the Nueva Granada collection (stated on label).
($2000-3000)
