Roman Imperial Coinage, abbreviated RIC, is a British catalogue of Roman Imperial currency, from the time of the Battle of Actium (31 BC) to Late Antiquity in 491 AD.
It is the result of many decades of work, from 1923 to 1994, and a successor to the previous 8-volume catalogue compiled by the numismatist Henry Cohen in the 19th century.
[1][2] It is the standard work for numismatic identification of coinage struck by authorisation of the Roman emperors.
The production of a chronological catalogue of Roman Imperial coinage was started in 1923 by Harold Mattingly, a numismatist at the British Museum, assisted by Edward Allen Sydenham.
[3] After Mattingly's death in 1964, Sutherland and R. A. G. Carson jointly took over editorship of the work.
