RUSSIA. Russian Soviet Federative Socialist Republic. 50 Kopeks, 1921-AT. Leningrad (St. Petersburg) Mint. PCGS MS-64+.
KM-Y-83. The SCARCER date for this brief two-year issue, the present example hangs on the edge of Gem status. Deep gray toning gives way to russet oranges near the peripheries, with some underlying luster throughout. A truly lovely piece worthy of a strong bid.
Estimate: $420 - $600
