type of coin struck after the formation of the Soviet Union in December 1923. The obverse shows the state arms and the denomination: [trans.] One rouble.. The reverse shows a worker and a peasant set against a rising sun, symbolizing the union of town and countryside in the light of the Soviet state's New Economic Policy. The new coins first appeared in circulation in February 1924.
During the period from 1828 to 1845 coins with the value of three, six and twelve roubles were struck from platinum from the Demidov mines in the Urals. The collection has a unique series of platinum trial coins struck at the St Petersburg Mint with the dies of ordinary silver coins of 1826-1827 (a rouble, a poltina or 50-kopeck piece and a 25-kopeck piece).
During the brief interregnum (27 November – 14 December 1825) following Alexander I's death, dies were prepared at the St Petersburg Mint and a few trial coins struck with a portrait of Constantine Pavlovich, who it was assumed would be the new emperor. On 14 December 1825, however, Constantine's younger brother Nicholas ascended to the throne instead. The trial coins and all the materials used in their minting (draft drawings, dies and tin copies of them) were immediately withdrawn and transferred to the offices of the Ministry of Finance. In 1878-1880 five of these exceedingly rare roubles, which had survived in the Ministry, were distributed among various collections with Alexander II's knowledge. One of them was acquired by the Hermitage, which later also acquired the draft drawings, dies and tin copies. A second coin is kept at Moscow's State Historical Museum. The other examples have all come to light abroad
The series of trial coins of 1798 is evidence of Paul's unrealized plans to introduce the yefimok, a coin worth one and a half roubles, into the Russian monetary system.
This gold coin, depicting a seated king on board a stylized ship, is a Russian imitation of the English nobles which circulated widely in Eastern Europe in the14th and 15th centuries. The date of this unique coin may be gauged approximately by the allusion in its inscription to the name of Ivan III's co-ruler and son, Ivan Ivanovich the Young (1471-1490). The sporadic minting of gold coins in the 2nd half of the 15th century, for use as diplomatic gifts, is evidence of the strengthening of the centralized Russian's state contacts with the countries of Western Europe.
