Siberia was home to many nomadic tribes, and in the 13th century came under the occupation of the Mongols. With the breakup of the Golden Horde late in the 15th century, the Khanate of Sibir was founded with its center at Tyumen. As Russia gained power, it started to expand its influence east of the Ural Mountains by sending in traders and Cossacks into the region. By the 16th century, Russia's control extended to the Pacific coast.

During the reign of Catherine II the Great, a mining colony was set up in the Altai Mountains to strike coins for the region. Coins were struck as early as 1763 up till 1781.

Catherine II of Russia, also known as Catherine the Great (1729-1796), was the most renowned and the longest-ruling female leader of Russia, reigning from 1762 until her death in 1796 at the age of 67. Born in Stettin, Pomerania, Prussia as Sophie Friederike Auguste von Anhalt-Zerbst-Dornburg, she came to power following a coup d'état when her husband, Peter III, was assassinated. Russia was revitalised under her reign, growing larger and stronger than ever and becoming recognised as one of the great powers of Europe. The period of Catherine the Great's rule, the Catherinian Era, is often considered the Golden Age of the Russian Empire and the Russian nobility.

A denga was a Russian monetary unit with a value latterly equal to ½ kopek. Production of dengas as minted coins began in the middle of the 14th century. Coins minted in the 18th century invariably showed the denomination as Denga, but during parts of the 19th century this was replaced by the word Denezhka, the diminutive form of Denga. Later still the denomination was shown simply as ½ Kopeck. The plural form of Denga, den'gi (деньги) has become the usual Russian word for 'money'.
