Constantine II, as Caesar, 316-337. Follis (Bronze, 15 mm, 0.95 g, 6 h), a contemporary imitation of an issue from Treveri. Uncertain mint in Gaul (?), circa 333-340 (?). Laureate, draped and cuirassed bust of Constantine II to left. Rev. CONSTAN/TINVS / CAESAR in three lines; above, star; below exergual line, STR. Cf. RIC 489 (for prototype). Extremely rare. Light deposits, otherwise, very fine.


Of the several thousands of official anepigraphic dynastic bronzes, not a single piece has an exergual line. In the contemporary imitations, a single die was engraved with an exergual line. It is known from two examples, this one and another showing the complete mint mark, 'STR'.
