 In 1924, after the formation of the USSR, it was decided to issue a new type of coins, on which the coat of arms of the RSFSR was replaced by the USSR coat of arms, but only test specimens were issued, they were dated 1925 and had exceptional rarity.The refusal of the metal chervonets was explained by the fact that the financial system of the country was sufficiently strong enough to give up free circulation of gold.In addition, abroad, seeing the strengthening of the chervonets, traders refused to calculate in a gold coin in favor of gold bars or foreign currency.
