Russian 5 Kopeks coin from 1778, made of copper and minted during the reign of Catherine the Great. The obverse features the imperial double-headed eagle, the symbol of the Russian Empire, with detailed decorations including a crown, scepter, and orb; the letters "Е.М" indicate the mint of Ekaterinburg. The reverse displays Catherine II’s monogram topped with a crown, with the date "1778" split on either side and surrounded by laurel and oak ornaments. The coin, typically measuring about 42 mm in diameter and weighing around 52.22 grams, shows signs of wear and a dark patina characteristic of antique copper, yet retains its main details clearly visible. A historical piece ideal for collectors of Russian numismatics, it represents a significant testimony of the imperial era.
