RUSSIA. 5 Kopeks, 1763-EM. Ekaterinburg Mint. Catherine II (the Great). NGC EF-40 Brown.
KM-C-59.3; Bit-609. A 5 Kopek of Catherine II struck over a 5 Kopek of Peter III (KM-C-44), with much of the undertype still visible on both sides. The surfaces are rather crude, but detail abounds on this curious piece, with light brown patina throughout.
Estimate: $60 - $100
