The papers collected in this volume were, with a couple of exceptions, presented at a conference on Celtic coinage held at the Ashmolean Museum and the Institute of Archaeology, Oxford, on 6th - 7th December 2001. With seventeen speakers and an audience of ninety, this was by far the largest gathering devoted specifically to Celtic numismatics since the 1989 Oxford, and indeed must have been one of the largest meetings devoted to Celtic coinage ever to have taken place.
