Alexander I 20 Kopecks 1823 CПБ-ПД MS65★ NGC, St. Petersburg mint, KM-C128, Bitkin-208. Full of wondrous, eye-popping appeal, this little gem easily captures the viewer's attention. The obverse features stunning toning from a broad range of the rainbow while barely containing the underlying luster. The reverse is equally as splendid, with the toning yielding to a light golden hue along with brilliant argent surfaces. An exceptionally pleasing piece.
