Tracing the provenance of an ancient coin has always been a challenging and time-consuming task. However, this has changed, as Ex-Numis® makes it quick and easy.
Ex-Numis® is the first website dedicated entirely to tracing the provenance of ancient coins from past auctions.
Our services are based on new digital image recognition technologies combined with our unique numismatic database. The database contains around one million ancient coins that have ever been illustrated in an auction catalogue over the last 100 years.
The wars in Syria and Iraq have heightened concerns that looted antiquities are being used to finance terrorist activities. Against this backdrop, there has been a growing number of new laws and regulations worldwide in recent years regulating the trade in and collection of ancient coins. New import restrictions in the US and new laws in Germany are just a small part of this. In other words, the future for collecting and trading in ancient coins does not look very bright.
In this context, the provenance (verified history) of a coin is of the utmost importance. Ex-Numis® helps collectors, coin dealers and auction houses to comply with current and future legislation.
Many ancient coins on the numismatic market have no known provenance. However, this does not mean that they are of illegal origin. It is possible that details of their provenance have simply been lost over time. Until now, tracing provenance has been a challenging and time-consuming task, undertaken only for high-value ancient coins. Thanks to Ex-Numis®, this task becomes quick and easy, and thus affordable for other ancient coins as well.
