About the CCI

The Celtic Coin Index is one of the largest datasets of Iron Age coinage worldwide and is a major source of evidence for late Iron Age Britain. For almost sixty years, the CCI staff and volunteers have been curating this card catalogue with written descriptions and (in many cases) photographs of the coins. The CCI has had a long and complex history, so we have shared some of its major milestones in the timeline below.

More information about the cards and their data can be found on the Info page.

The project to create the Celtic Coin Index Digital using the Numishare platform and Nomisma.org ontology was undertaken by a team at the University of Oxford, supported financially by the Royal Numismatic Society, the British Numismatic Society, the University of Oxford Barclay Head Fund, and private donors. The team includes: Dr Courtney Nimura (Institute of Archaeology), Professor Chris Howgego (Ashmolean Museum of Art & Archaeology), Professor Chris Gosden (Institute of Archaeology), Dr John Talbot (Celtic Coin Index), and Molly Masterson (DPhil student / Research Assistant). The project has worked in partnership with a number of specialists, who generously donated their time and expertise: Dr Philip de Jersey (Guernsey Museum & Art Gallery), Dr Eleanor Ghey (British Museum), Dr Ian Leins (English Heritage), and Dr David Wigg-Wolf (Römisch-Germanische Kommission des Deutschen Archäologischen Instituts). Ethan Gruber (American Numismatic Society) created the website and the necessary Nomisma concepts for the project.

We are also involved with an international cooperation, Online Celtic Coinage, to develop an online union catalogue of typologies of pre-Roman Iron Age coinages run out of the German Archaeological Institute, Romano-Germanic Commission by David Wigg-Wolf.

The CCID website supports the Portable Antiquities Scheme (PAS). The PAS seeks to transform knowledge and understanding of the archaeology and history of England and Wales through the recording of archaeological finds discovered by the public. Finders of Iron Age coins are strongly encouraged to record their discoveries with the scheme, which is administered by the British Museum and National Museum Wales: https://finds.org.uk/. In England, Wales and Northern Ireland, all finders of groups of coins from the same finds, over 300 years old, have a legal obligation to report such items under the Treasure Act 1996. Separate legislation applies in other parts of the British Isles. For further information, see https://finds.org.uk/treasure.
