Copper "Siberian" coins were planned to complement the silver coins in denomination of 10, 15 and 20 cents, but in mass production they did not. There are rare remakes of two types (monogram and profile), minted by the mint at a later time.
The obverse depicts a portrait of Catherine II in profile, face to the right, below the letters "СПБ"(Saint-Petersburg). On a circle the inscription: "Б•М•ЕКАТЕРИНА•II•IМП•IСАМОД•ВСЕРОС"
The reverse depicts the emblem of the Siberian Kingdom - two Sables standing on hind legs, each of them with one paw holding the downward-facing arrow, and the other supports the crown. In a circle the inscription - "•МОНЕТА•ЦЕНА•ДВАТЦАТЬ•КОПЕЕКЪ•" At the top of the year of issue "1764".
