The project is undertaken in close cooperation with the Israel Antiquities Authority (IAA). The goal of the project is to process and catalogue all of the post-reformatory Umayyad coins (696–750 A.D.) that were found in excavations in Israel and which are stored in the coin collection of the IAA. On the basis of this globally unique database, completely new pathways to our understanding of the coinage and monetary system in the early Islamic period will be opened up. On the one hand, based on the cumulative archaeological evidence it has been possible to narrow down a number of mints that until now have not been localized, even if they cannot be precisely identified. On the other hand, the study of coins elucidates cash flows and regional relationships better than almost any other type of material evidence. In addition, the numismatic investigation of the early Islamic period will gain significant stimuli, not only due to the amount of published material but also due to the unusually high quality of data deriving from archaeological provenances. Not least, archaeology in general will profit from this analysis.
