The Roman Imperial Coinage (abbreviated RIC) is a typological catalogue of Roman Imperial coins from the Battle of Actium in 31 BC to Late Antiquity in 491 AD. It aims to offer a complete and chronological reconstruction of the whole coinage produced by each of the Roman emperors. The series was started in 1923, and has become the standard work for numismatic reference. It was previously comprised of 10 volumes in 13 parts, some of which are currently being revised and will be divided differently. This brand-new volume, published to celebrate the centenary of the series, covers the Gallic Empire from AD 260-274.
