Argentina (River Plate Provinces), La Rioja mint, 8 reales, 1828P, encapsulated NGC MS 63, finest known in NGC census. Janson-30; KM-20. With muted luster all over and practically devoid of wear but with lightly struck centers as usual (full sunface), a gorgeous specimen that undoubtedly saw no circulation since the early 1800s. NGC #2730693-001. Probably from one of the famous 1829 "tapados" (hoards) of Juan Facundo Quiroga (see accompanying article).
