Kolpino Mint

1810-1821

Copper coins during the reign of Alexander I until 1810 were minted according to the previous system in weight norms (16 rubles per pound ) and in the traditional set of denominations preserved from the XVIII century : 5, 2, 1 kopek , money (1/2 kopek) and half (1/4 penny). Since 1810, the weight norms were changed, according to which it was planned to mint coins for 24 rubles from the pond. The re-minting of coins, carried out earlier by each subsequent ruler of the Russian Empire , could no longer take place. The collected old coin began to melt and a new one was cast from the resulting metal. The rapid replacement of all copper was not within the power of the production capacities of the three national mints that existed at that time - Petersburg , Yekaterinburg and Kolyvan .

Therefore, in order to help these mints by state order, in 1810, additional minting of copper coins was organized and carried out for several years at the Izhora plant, which then belonged to the Naval Department . As a result of this, a national mint, called Kolpinsky or Izhora, was organized at the plants. The first series of 1810, minted in the yard, consisted of coins in denominations of 2, 1 kopecks and money (this word has been written with “b” since the beginning of the 19th century) ^[2] .

As a staffing mint, minting national coins, Kolpinsky Yard worked from 1810 to 1821 ^[3] , after which it was closed.

1840-1843 / 1844

Under Nicholas I , a monetary reform of 1839-1843 was carried out . As a result of which all transactions were ordered to be carried out is equated to silver . It turned out that the monetary stop was changed (coinage was reduced from 36 to 16 rubles per pound), the denominations (a coin of 3 kopecks was added), the appearance changed (the inscription “... in silver” appeared near the denomination) and the sizes of copper coins. Due to the need to cope with the new processing of copper money supply, Kolpinsky Yard was again involved in 1840 as a temporary one and worked as such until 1843 (in some sources, until 1844 ^[1] ).

• In 1810, the courtyard issued two-copecks coins with the designation “KM” (Kolpino coin) and with the sign of Mintzmeister M. Kleiner - MK ^[4] . From 1810 to the 1840s, the initials of persons responsible for issuing persons (under the coat of arms) were placed on a copper coin of the Russian Empire ^[2] .

• To avoid coincidence with the sign of the Kolyvan Mint (also “KM”), the letter designation “IM” (Izhora coin) was introduced for the yard, and all subsequent issues of 1810-1821. made with the sign "IM".

• In the years 1840-1843 / 1844, minting was carried out with stamps with the designation of the St. Petersburg Mint - “SPM” ^{[4] [1]} .
