1 Kopeck - Nikolai I ЕМ

The EM mintmark denotes the Yekaterinburg Mint in the Urals, which handled the bulk of Russia's copper coinage throughout the nineteenth century — a practical arrangement given the proximity to Siberian copper deposits. Nicholas I's monetary reforms of 1839, just after this series closed, would consolidate the coinage system under Kankrin's silver standard, making these pre-reform copper kopecks among the last issues struck under the old assignat-based reckoning.
