Russia 1980 USSR 20 Kopeks

The Soviet currency had its own name in all Soviet languages, sometimes quite different from its Russian designation. All banknotes had the currency name and their nominal printed in the languages of every Soviet Republic. The first ruble issued for the Socialist government was a preliminary issue still based on the previous issue of the ruble prior to the Russian Revolution of 1917. They are all in banknote form and started their issue in 1919. The first coinage after the Russian civil war was minted in 1921–1923 with silver coins in denominations of 10, 15, 20 and 50 kopecks and 1 ruble. In 1924, copper coins were introduced in denominations of 1-, 2-, 3 and 5 kopecks, together with new silver 10-, 15 and 20 kopecks, 1 poltinnik (50 kopecks) and 1 ruble. From this issue onward, the coins were minted in the name of the USSR (Union of the Soviet Socialist Republics).

 All silver coins were returned and melted down. In 1935, the reverse of the 10-, 15-, and 20-kopecks coins were redesigned again with a more simple Art Deco inspired design, with the obverse of all denominations also redesigned, having the "Workers of the world, unite!" slogan dropped. The change of the obverse designs did not affect all 1-, 2-, 3-, and 5-kopecks coins immediately, as some 1935 issues bore the "Workers of the World" design while some bore the new "CCCP" design. The state emblem also went through a series of changes between 1935 and 1957 as new soviet republics were added or created, this can be noted by the number of "ribbons" wrapped around the wheat sheaves. This coin series remained in circulation during and after the monetary reform of 1947 and was finally discontinued in 1961.
