||Ferdinand I gold Siege of Vienna Klippe Ducat 1529, Vienna mint, Fr-22, XF Details (Tooled) NGC. A very scarce example of gold siege issues, this example displays an above-average strike for the type with light circulation on an unbent flan. The tooling referred to by NGC is evident throughout the fields on both sides. These ducats were issued during the Ottoman Siege of Vienna from September through October of 1529. The illness and lack of supplies in the Ottoman camp caused them to risk an all-out assault on October 12th, but they were beaten back by the city's defenders. This siege halted Ottoman expansion into Central Europe, forcing them to focus their expansion into the Mediterranean, culminating decades later in the Siege of Malta.
