Struck between 1977 and 1980, this gold coin series was minted in celebration of the 1980 Moscow Summer Olympics. Each piece contains exactly 0.5 troy ounces of gold with a purity of 0.900, representing a significant commemorative release from the Soviet era. The reverse of the coin features the prominent Coat of Arms of the Soviet Union, positioned above the 100 Roubles denomination and the Cyrillic abbreviation CCCP, which stands for the Union of Soviet Socialist Republics. While the reverse remains consistent, the obverse design varies depending on the specific year of issue and the particular Olympic theme depicted. These coins were produced in both Brilliant Uncirculated and Proof finishes, showcasing the detailed artistry of the era. The inscriptions include the Cyrillic text for the XXII Olympic Games and the state abbreviation, making these coins a fascinating window into late twentieth-century sporting history.
