A gold coin minted in Prague in 1629, celebrating the coronation of Holy Roman Emperor Ferdinand III as King of Bohemia, was sold at auction October 31st for €360,000 ($461,000.) The coin was the highlight in an exceptional Künker’s Rarities coin auction in Osnabrück, Germany.
Believed to be the only example in private hands, the 40 ducat gold piece was estimated at half the eventual hammer price. Ferdinand III (1608-1657) was son of the Holy Roman Emperor Ferdinand II. He was made Archduke of Austria in 1621, King of Hungary in 1625, King of Bohemia in 1627, succeeded his father as Emperor in 1637, during the Thirty Years War.
