RUSSIA. Ruble, 1779. St. Petersburg Mint. Catherine II (the Great). PCGS Genuine--Planchet Flaw, AU Details Gold Shield.Fr-135; KM-C-76; Bit-115. Despite the noted planchet defect--located at the rim on the obverse, in front of Catherines portrait--this delightful example exhibits very little in the way of handling or marks, and retains a great deal of brilliance.
