In this paper we present the results of ten years of die studies on the Roman silver coinage of the Second Punic War. For the first time a correspondence between coinage production and War costs is attempted. A special focus is placed on the victoriatus. In fact the preliminary results of the ongoing Victoriatus Project point to a much larger size of this denomination than believed so far. This has a direct impact also on the way this coinage has to be regarded and its role during the War, which will be discussed with some detail in the paper.
