Nash, Daphne. Coinage in the Celtic World. (London, 1987)

Over 200 illustrations of coins at actual size and 6 maps. The ancient Celtic world reached its zenith in the second century BC when it stretched from Ireland to Galatia and from central Europe to northern Italy and parts of Spain. From the 6th century BC until the early 1st century AD the Celts were among the most important neighbours of the expanding Mediterranean states and empires; this book takes a fresh look at the complex relationship of the two worlds and provides a comprehensive historical background to Celtic coinage.  Spink 2004 reprint, paperback, 8.5" x 5.4", 160 pages.
