The chervonets was introduced by the Soviet government in the reform of 1922-1924 years as a currency tied to gold. Coins were mainly used in foreign trade operations, and among the population went to paper cups. Chasing was made in 1923-1926 years, after which the bulk (especially 1925) went to the smelter. The coins of this period are known with the date "1923" and "1925". From 1975 to 1982 the state Bank of the USSR produced massive novodel minting of coins, repeating the design in 1923, but with the new date and designation of the mint on the edge (instead of the initials of mintmaster). Since 2001, these coins are used as investment banks and are implemented at a special price. To take back to the Bank coins can be roughly a loss of 30% of the original value.
