1/2 As Cantharus series

The heavy cast bronzes of central Italy from this period exist in a numismatic grey zone — their issuing authorities remain unresolved, and the cantharus series is no exception. Attribution debates have shuffled these pieces between Umbrian, Etruscan, and Latin candidates for over a century without consensus. At 145 grams, this falls within the expected range for an aes grave half-as on the heavy Oscan-influenced standard, before Rome's progressive reduction of the libral system rendered such weights obsolete by the late third century.
