Russia: Catherine II Rouble 1777 CПБ ΘΛ AU58 NGC, St. Petersburg mint, KM-C67b, Dav-1685, Bitkin-224, Diakov-357. With only a few lightly scattered and unobtrusive marks, this pleasingly toned piece radiates with flashy brilliance. Just a hint of wear on the highest of points precludes it from attaining mint state.
