The uncertain Umbrian attribution reflects a genuine scholarly impasse — several inland communities north of Rome were striking heavy cast bronze during this window, and die links alone have not resolved the question of which civic authority commissioned this series. What is clear is the timing: production falls squarely across the Second Punic War's opening years, when Rome's Italian allies were under enormous pressure to demonstrate loyalty through material support, including coinage that integrated with the Roman aes grave system.
Haeberlin's foundational analysis of cast bronze remains the primary framework for attribution, though subsequent scholarship by Thurlow and Vecchi refined the regional groupings without settling the issuer.
