RUSSIA. Ruble, 1762-CNB HK. St. Petersburg Mint. Peter III. PCGS MS-62. KM-C-47.2; Dav-1682; Bit-11. Milled Edge. This supremely attractive Ruble is a very difficult coin to find in Mint State levels of preservation, with less than 10 examples graded higher than this one between PCGS and NGC. This example of the one-year type has a charm owing to its subdued luster and white color on pebbled surfaces from a rusty die. Some light hairlines are present in the fields, as to be expected for the grade, but nothing to distract or dissuade the collector of these popular pieces.
