Focused specifically on the coin collecting space, it integrates data for more than 16.7 million lots from over 16,000 auctions held by 474 leading auction houses worldwide. It is an essential research and lookup tool for the global trade and study of ancient coins, banknotes, and antique collectibles.
The platform's core function is querying information on past auction lots. It supports categorization by multiple types: ancient coins, modern coins, banknotes, medals, and antiques, and allows multi-dimensional filtering by auction house, auction date, hammer price range, and more. Its standout feature is reverse image search, which lets you quickly locate coins of the same variety and from the same die for pedigree research and authentication. It supports multi-language interfaces and multi-currency price display, and also offers user comments and interaction.
For pricing: basic text search is completely free. Advanced features require a paid premium membership. Image search is pay-per-use, starting at 0.7 EUR per search, and premium members receive 20 free search credits.
Pros: It has an extremely large data coverage, with historical records spanning more than 17 years. It includes almost all public auction data from major global numismatic auction houses. Basic features have no usage barriers, the image search function delivers huge value for professional researchers, and the interface is clean and straightforward.
Cons: The paywall for advanced features is relatively high. There is no Chinese interface, which makes it unfriendly for casual users in China. Bulk data scraping is prohibited, it only offers lookup services and does not support transactions, and customer support is only available via email with limited response speed.
This website is suitable for professional coin collectors, antique dealers, and numismatic researchers. Users in China can access it directly without any circumvention tools.
