R.S.F.S.R. silver Proof 20 Kopecks 1923 PR66 NGC, KM-Y82. A amazing matured Proof - its mirrored fields have developed a gradated tone, a light gold in the centers, darkening as it reaches the peripheries; however, none of their reflectivity has been lost. Of a crisp strike and tremendous eye-appeal, this would be a difficult type to improve on. A superb and seldom-seen offering for the selective collector.
