Medellin, Colombia, gold 10 pesos, 1876/5, NGC MS 66. Restrepo-334.4; KM-141.4. Gorgeous luster and color (the legends draped in magenta hues), slightly grainy surfaces as made, a very close second to the top coin in the NGC census at MS 66+, which hammered for $5,750 in 2017 (Heritage).
Estimate: 3500 - 5000 USD
