X#M2. Zurich. 300th Anniversary of Zwingli's First Preaching in Zurich Gold Medallic Ducat, 1819. Obverse: Mantled bust of Ulrich Zwingli right, wearing minister's cap; Reverse: Legend in ten lines. A great Reformation-related type, this glistening Gem radiates with a high degree of mirrored brilliance and also offers slightly frosted devices. Undoubtedly one of the finest that one can hope to encounter. Tied for Finest Known!
