RPC volume X covers all Roman provincial coinage issues from the joint reign of Valerian and Gallienus through the year 12 of Diocletian (AD 253–295/6). It includes over 5,800 type descriptions and 48,000 coins from 153 cities. The geography extends from Moesia Superior to Egypt. The greatest concentration of mints is in western and southern Asia Minor, though the most prolific mint was Alexandria, whose lifespan extended two decades beyond all other mints.

William E. Metcalf is the author of this volume. His work on it spans his tenure at the American Numismatic Society and at Yale University and has extended into his retirement to Maryland. Andrew Burnett has provided significant assistance and encouragement during this long effort, and Jerome Mairat has provided many additions and revisions. George Watson and Clifford Thring have also made contributions.

Further additions and corrections will be incorporated into the printed volume. Please submit feedback through RPC online.
