It is impossible to imagine a Swiss auction house without specialists in the field of Swiss numismatics. In addition to Jürg Richter, SINCONA AG has a second expert in Ruedi Kunzmann, who has seen almost everything that has ever been minted on Swiss soil.

He has been involved in numismatics for over 50 years and has been observing the local auction scene for just as long. He is the author of many specialist and ‘popular’ numismatic articles. His numismatic areas of expertise include Swiss cantonal coins and banknotes. Ask him a question and you will be met with great competence and friendliness.
