February 11, 2016 – In the last years it has become more and more important to know a coins’ pedigree. On the one hand there are legal requirements, which ask for due diligence. On the other, coins deriving from large, historical collections realize higher prices, compared to coins with no known provenance. Until now, the only thing to do, in order to find out from which collection, that is auction the coin stems from, was to go through thousands of auctions catalogues.

A new online tool by Ex-Numis® is now available for collectors, museums and coin dealers, which can be used to look for provenances.

Image recognition program for prevenance research

Dr Jonas Flueck, a young scholar with a lot of experience in the coin auction business, is the founder of this website. With the help of an image recognition program, the tool compares images fed into the system to an extensive database. The material for comparison is exceptional: the database contains almost a million images of ancient coins and is constantly expanded. The images come from auction catalogues starting in the 19th century up to 2000. The clients’ coin will be compared to images from auction catalogues such as Ars Classica, Otto Helbing, MMAG, Ratto, Rolin & Feuardent and many more.
