Roman Imperial Coinage

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.

It is the standard work for numismatic identification of coinage struck by authorisation of the Roman emperors.
