Æ25 - Trebonianus Gallus ΘΕΜΙϹΩΝΕΩΝ

Themisonium was a minor Phrygian city whose civic coinage under Trebonianus Gallus represents one of the later gasps of the Greek imperial bronze tradition — the whole system collapsed within a generation as the Roman monetary economy centralized and third-century pressures made local civic minting increasingly impractical. The city sat in the Conventus of Philomelium, an assize district whose member communities were granted the administrative framework to issue bronze for local exchange.

IX#906 is not a heavily documented variety. Phrygian civic issues of this reign are sparsely represented in major collections, and die studies for Themisonium remain incomplete.
