RUSSIA. 10 Rubles, 1780-CNB. St. Petersburg Mint. Catherine II (the Great). PCGS AU-58. Fr-129b; KM-C-79b; Bit-38. This attractive specimen is a hard issue to find, with only slightly more than a score being registered at NGC or PCGS. This particular example is host to a slightly soft strike, but has an attractive original mint sheen to the gold. A very beautiful and entrancing issue. From the Mark and Lottie Salton Collection.
