Provenance research:


To the best of our possibilities, we would like to give to our clients provenance information’s of pieces sold by us.

The Galerie Cahn which has existed for four generations has old archives including the Münzhandlung AG (1930-1942), the Münzen und Medaillen AG (1942-1988) and the H.A.C. AG (1988-1999) companies. The objects acquired before 1999 were sold by Herbert A. Cahn. We do have considerable archival material for the MuM AG, particularly for the years 1954-1986 contrary to HAC's company archival situation which is much more fragmentary. The search for provenance may therefore prove more complex. The statute of limitations for archiving administrative documents prior to 2005 was limited by law to ten years and one day in Switzerland, meaning that we no longer have the complete history of the former companies which have been liquidated.

The Jean-David Cahn AG was founded in 1999. What you acquired directly from this company is free of charge. Provenance researches from previous now liquidated companies have to be charged as they take much more time.
