In 1922 the name of the country was broadened to Union of Soviet Socialist Republics (USSR or, in cyrillic, CCCP) but this was not reflected on the gold coinage of 1923. In 1924 the designs were changed and CCCP used for the first time.
Designs of 1924 are better executed than those of 1921 and show artistic skill. The ruble has on the obverse a young man showing the new way to an elderly peasant while the half ruble has a blacksmith symbolically forging a new nation. The small silver underwent minor changes only. There was a limited striking of redesigned gold coins in 1925 but these were later melted and only a single example is thought to exist. Copper coins were also struck beginning in 1924, using the 50-ruble standard of 1867.
Soviet authorities released the gold, silver and copper coins to circulation in early 1924.
There had been a series of currency "exchanges" for the paper ruble in preceding years (several million "old" to one "new" was a common rate) and the introduction of hard currency stabilized the monetary system. The public quickly' hoarded the gold coinage and no more was issued.
In order to have enough coinage on hand to keep the reform moving, the USSR contracted abroad for copper 5-kopeck coins and half rubles. The former were struck by Heaton’s in Birmingham, while the silver coins were produced by the Royal Mint in London. Some of the copper coinage of 1924 was struck by a Leningrad factory. (Petrograd had been renamed in 1924 after the death of Lenin.)
