The USSR (or the soviet) rouble story has many periods, with it's rises and falls. The soviet rouble was the strongest after 1924,
when golden chervonetz was introduced. The history of this currency ended in 1992 and 1993, when former USSR republics
refused from using it as a legal tender. Russia, as the heir of the USSR, introduced the russian rouble in 1993. All banknotes
represented above are no longer in use (since 1993). 1 soviet rouble equalled 100 kopecks.
