The Ekaterinburg mint was active 1727-1876. The only reason why there was a mint from Ekaterninburg is because Ekaterninburg is full of natural resources and it still does up to now. In 1725, striking of copper "plates" coins, inspired by the Swedish copper plates was tried out, but it was not terribly successful. Ekaterinburg used to mint copper coins, and later supplied copper planchets for Moscow Mints. Ekaterinburg's minting technology was pretty far behind compared to both Moscow and Saint Petersburg, and this could be told from their crude strike, which still existed until the late 1820s. Mintmark for this mint is denoted by E.M.
