RUSSIA. Ruble, 1741-CNB. St. Petersburg Mint. Ivan III. NGC EF-40. KM-207.2; Dav-1676; Bit-27. This particular example of the ever popular Ivan Ruble gives cool steely-gray surfaces warmed by faint tinges of golden tone. Some light wear is present on the highpoints of the design, with limited marks for the grade. These Ivan Rubles are hard to acquire in collectible condition, and this piece is the finest example certified by NGC for the Bitkin number. A must have for any collection of Russian portrait Rubles, this example will always be a mainstay of Russian numismatics.
