Catherine II gold 10 Roubles 1776/5-CПБ AU55 NGC, St. Petersburg mint, KM-C79a (overdate unlisted), Bit-32 (R; same). A seldom-seen type that becomes downright rare in grades approaching Mint State, this example hosting an undoubtedly scarce overdate to boot. Very lightly circulated, with near-full luster retained in the fields, areas of the reverse peripheries especially vibrant and essentially glowing with molten sun-gold.
