About Us

Münzen und Medaillen AG (M&M) was established in Basel, Switzerland in 1941. The founders were the brothers Dr. Erich Cahn and Dr. Herbert Cahn, professional numismatists, together with several eminent Swiss collectors. M&M became well-known in the post WWII period for its monthly fixed price lists, a series which continued for over 60 years. The firm has also conducted over 100 auctions, including great collections such as the Rosen (Ancient electrum), Bally (Roman), Kohlmoos (crown-sized coins) Sutter (Italy and Sicily) and many others. In partnership with Leu Numismatik, M&M also auctioned the Kunstfrend and Niggeler collections.

In the 1990s, Dr. Hans Voegtli assumed responsibility for Ancient coins and Dr. Bernhard Schulte for Medieval and modern coins. In 1996, M&M Numismatics opened in Washington, DC with Lucien Birkler as managing director. In 1997, M&M Deutschland opened in Weil am Rein, Germany, with Joachim Stollhoff as managing director. The Basel office closed in 2004, but both the American and German firms remain active. Today both companies continue the long tradition of serving collectors and look forward to serving your numismatics needs now and in the future.
