I would like to submit the following reference for medieval coinage:
Metcalf, D. M., The Coinage of South Germany in the Thirteenth Century, Spink & Son, Ltd., London, 1961.
This book provides a reference for coins of southern Germany, Switzerland, and Austria, including Regensburg, Niederbayern, Swabia, Munich, Augsburg, Freising, Konstanz, Basel, Zurich, Friesach, St. Veit, Vienna, and the Danube area during the 13th century.
