This coin is part of a special emission struck in spring-summer 283, at the beginning of Carus' Persian campaign, to celebrate the elevation of Carinus and Numerian to the rank of augusti. Carus was the first emperor since Gallienus who had adult sons, and he not only used this to entrust the western part of the empire to his firstborn Carinus while campaigning with his younger son Numerian in the East, but also for his imperial propaganda. The reverse of this denarius praises Carinus and Numerian as the 'public hope', thus announcing the beginning of a new and prosperous era under the rule of the dynasty of Carus
