1 Triens Cantharus series

The Cantharus series belongs to the aes grave tradition of cast bronze coinage produced across central Italy during the period Rome was consolidating control over the peninsula. Attribution remains contested — the issuing authority has never been conclusively identified, with various scholars placing production in Umbria, the ager Gallicus, or among communities of uncertain Oscan or Latin affiliation. Haeberlin's foundational work catalogued the physical typology without resolving the question of origin, and subsequent scholarship has not settled it.

At this weight, the piece represents a full triens before significant reduction — earlier in the sequence of fractional diminishment that would characterize aes grave denominations through the Second Punic War.
