Poland, Lithuania. John II Casimir Vasa. 1 Solidus 8x 1661-1666 (No reserve price)

The '1 Solidus' coin issued between 1661-1666 under John II Casimir Vasa symbolizes an important period in Polish-Lithuanian history. John II Casimir was the King of Poland and Grand Duke of Lithuania during the 17th century, a time marked by wars and political upheavals. The solidus, originally a Roman gold coin, had been adapted as a silver or billon denomination in later European coinages, often used for smaller transactions. Coins from this era bear national insignia, royal portraits, and mint marks which are key for historical and numismatic studies. Owning such coins offers collectors a tangible connection to the turbulent history of the Commonwealth and the artistry of 17th-century mints in Vilnius and other regional centers.
