RUSSIA. Ruble, 1804-CNB OT. St. Petersburg Mint. Alexander I. NGC MS-61. KM-C-125; Bit-38. Wholly argent and rather transfixing, this immensely impressive Mint State specimen yields a vibrant, lustrous nature along with a pleasing and well executed strike. As such, an example from early in Alexanders reign that should undoubtedly generate great enthusiasm. From the Sigma Collection.
