1 Triens

Heavy cast bronzes of this class belong to the so-called "aes grave" tradition, produced by a cluster of central Italian mints whose precise identities remain disputed. The attribution to an uncertain issuer is not evasion — it reflects a genuine scholarly impasse, with candidates including Hatria, Luceria, and several smaller communities caught between Roman expansion and Samnite resistance during the third century.

At roughly a third of the as by weight, the triens occupied a practical middle denomination in local exchange. Haeberlin's foundational typological work and the subsequent Thurlow-Vecchi corpus have narrowed the field without closing it.
