1 Uncia Wheel / Krater

Etruscan bronze coinage of this period operated largely outside the Roman monetary framework expanding around it, produced by city-states whose political autonomy was already eroding. The specific mint for this type remains unattributed — a problem complicated by the near-total absence of Etruscan mint signatures and the difficulty of provenancing pieces without excavation context. Weight standards among Etruscan bronze issues varied considerably from city to city, making die-linkage studies the primary tool for grouping emissions.

The uncia represents the twelfth-part division of the Etruscan as, a system running parallel to — and occasionally intersecting with — the Roman libral standard.
