RUSSIA. Poltina (1/2 Ruble), 1885-CNB AT. St. Petersburg Mint. Alexander III. NGC Unc Details--Cleaned. KM-Y-24; Bit-53. Mintage: 511. The final date in this particular series, and one which boasts a very scant mintage figure, this <strong>RARE</strong> example does exhibit some minor cleaning as noted, but that matters little with respect to its overall appeal. Highly brilliant and attractive, with a great lustrous nature and very subtle tone. From the Sigma Collection.
