RUSSIA. Ruble, 1776-CNB RY. St. Petersburg Mint. Catherine II (the Great). PCGS MS-62 Gold Shield. Dav-1684; KM-C-67a.2; Bit-221. An ever-popular date owing to its importance with American collectors, this year also represents the final year of issue for the type. Delightfully attractive and seemingly a bit conservatively graded, this piece presents a good deal of shimmering brilliance as well as an alluring pastel palette dominated by a charming seafoam green nature.
