1 Rouble 1985

This serie was a result of a monetary reform of 1961. 1 "new" rouble was worth of 10 "old" roubles. These coins were used for 30 years, they were the most long lived serie of USSR-coins. There are numerous varieties, especially in the national emblem. In 1991, a mint mark appeared on the coins, a cyrillic "L" for Leningrad and "M" for Moscow.
Coins are made of Copper-Nickel-Zink. Edges are reeded except in 50 Kopek and 1 Rouble, which have edge letterings * ОДИН РУБЛЬ * (date) on 1 Rouble and * ПЯТЬДЕСЯТ KOПEEK * (date) on 50 Kopek.
The "State Bank"-coins replaced this serie in 1991 right before the collapse of the USSR.
