Mint: Arles (Arelatum/Constantina)
Abbreviation: AR, ARL, CON, CONST
The mint at Arles was opened in AD 313. Early issues use the AR or ARL mintmark. In AD 318 the city was renamed Constantina to mark it as the birthplace of Constantine II. From this time the mintmark CONST or CON was used. After the death of Constantine II in AD 340, the mintmark ARL was reintroduced, lasting until AD 353. After this time it remained CON or CONST.
