The yefimok (Russian: ефимок; pl. ефимки, yefimki) is the national currency and legal tender of the Alaskan Democratic Federative Republic. The currency is divided into 100 sotkas (сотки, sotki). The ISO code of the yefimok is AKY.
Several currencies were officially and unofficially used within Russian America throughout the 19th Century. As was with the whole of the Russian Empire, the ruble was primarily used within the colonies. Physical ruble coins and banknotes remained rare across Russian America prior to the 1850s. It was because of this that the Russian-American Company issued parchments of sealskin which would be equated to rubles. These parchments could only be redeemed in company-owned general stores and were often the primary means of payment for those under the employment of the company (particularly fur traders). These company-oriented parchments fell out of use by the latter half of the century as the economy and population of Russian America grew (allowing for physical rubles to become readily available).
The British pound, the Mexican peso, and the United States dollar were unofficially used in the southern settlements as an alternative to the ruble or the RAC-issued parchments. Dollars and pesos were colloquially referred to as yefimoks by the settlers as an umbrella term (the name being the Russian equivalent to the piece of eight and the thaler). Beginning in 1856, the Colony of Columbia began circulating a colonial currency that would continue to be used for several following the Columbia Purchase.
Following the Russian Revolution and throughout the Alaskan Wars, several currencies were officially circulated across the region. The yefimok became the preferred currency of the region and would become the single national currency in 1930.
