The website monedaiberica.org offers a new complete catalogue of the ancient coinages of the Iberian Peninsula and the south of France struck between the 6th and 1st centuries BC. The new project has been developed within the framework of the international ARCH project (Ancient Coinages as Related Cultural Heritage) in collaboration with the University of Oxford and the Bibliothèque nationale de France. The catalogue organizes the coin series from more than 200 mints, including 4,000 types from the Greek, Punic, Iberian, Celtiberian, Vasconian and Lusitanian cultures. The project collects for research purposes over 100,000 coins with images from museums, auctions and private collections. The website links different international projects. The contents are managed by Dédalo/Numisdata, a research and publishing open-source system based on web standards. This database enables promotes work in collaborative environments, and offers powerful resources for managing languages, users and projects.
