RUSSIA. Soviet Union. 10 Kopeks, 1927. Leningrad (St. Petersburg) Mint. PCGS PROOF-66 Cameo. KM-Y-86. <strong>RARELY</strong> encountered as a proof striking, this enchanting Gem exudes immense eye appeal in the form of some rather enticing pastel toning and shimmering vibrancy. As would be expected, the detail is sharp and exacting, making this a strong contender for those seeking the difficult proofs of the opening decade of the Soviet Union.
