In 1770-1771 years in Russia was the second attempt to establish a mint out of copper, because silver did not have much. Production was carried out at the Sestroretsk mint in the vicinity of St. Petersburg, as a raw material used in the old guns. The circles for the coins are cut from bars of copper, which proved to be quite labor-intensive. On both sides of rubles deposited Krama specially prepared stamp.

Varieties of Sestroretsk ruble:
In 1770, there was established the production of RUB on a thick circle with a diameter of 72.5 mm and a thickness of 26 mm, but the manufacture of such coins was too complex. In the following year procured the stamps with the date "1771" minted rubles for workpieces with a diameter of 101 mm, thickness 15 mm. New rubles was very difficult to use, so I went back to the previous version. In the same year produced a limited coinage "Pugachev" ruble silver with a silver ruble, but a stamp from the "Sestroretsk". The name was given much later in honor of the Pugachev rebellion, which occurred in this year. Sestroretskie rubles, as "Pugachev" preserved in very small quantities and are of exceptional value. Ruble diameter of 101 mm is generally known in a single copy.
