This antoninianus shows Maximian in the standard radiate, draped, and cuirassed military bust typical of the tetrarchic period. The reverse depicts the emperor standing at left, receiving a small Victory figure from Jupiter at right, a type that fuses two ideas into a single composition: Jupiter's endorsement of Maximian as his chosen agent on earth, and Victory herself as the tangible gift of that divine favor. The legend CONCORDIA MILITVM, "the harmony of the soldiers," reinforces the message with an appeal to army loyalty, a constant concern for third-century emperors who owed their thrones to military acclamation. This example has a great green patina.

Concordia Militum became one of the most heavily used reverse legends of the later third century, appearing under a long succession of soldier-emperors as a direct address to the legions whose support determined the fate of every reign. Paired here with the Jupiter-and-Victory scene, the type presents Maximian's authority as resting on two pillars at once: the favor of the gods above and the loyalty of the army below, a formula that became the ideological backbone of the tetrarchic system he helped establish alongside Diocletian.
