This talk gives an overview of the online Greek die study database developed by the ERC “SILVER”. Based on the two "Recueils quantitatifs des émissions monétaires" by Fr. de Callataÿ (1997, 2003) whose different categories of data it reproduces, it expands the number of cases to more than 1000. The site allows for the interoperability with other websites, quantitative data for each series and an overview of the obverse dies for the recorded series. Furthermore, each die has a dedicated page to which institutions with online catalogues can link their coins. The database also includes die studies authors pages and an interactive map showing the die studies according to several criteria. Although the database was conceived for Greek coins, we plan to add the data of Republicans and Imperials. This will allow for the first time a quantitative study of coins produced throughout the ancient Mediterranean.
