1856 Russia Rouble NGC PF63  This rare, lustrous, proof rouble exhibits lovely green, blue, and violet toning, which is darker around the edges and lighter on the devices. The coin is sharply struck as with full details in the centers of both sides and complete dentils around the peripheries. The surfaces are virtually mark-free and indicative of a higher grade. Not a trace of wear is found on the coin, in keeping with the grade. This coin is tied for the second finest graded by NGC. The population report shows 3 in PF 63 with 2 better.
