RUSSIA. 5 Rubles, 1766-CNB. St. Petersburg Mint. Catherine II (the Great). PCGS MS-61. Fr-130A; KM-C-78A; Bit-60. Narrow portrait type. <strong>RARE</strong> in this state of preservation and highly sought after as such, this enchanting, Mint State specimen exhibits some fairly unobtrusive shallow adjustment marks on obverse, though some light scratches near 7 oclock on the reverse are noted for completeness. A lustrous, bright example, and one that is sure to excite the connoisseur of Russian numismatics.
