Tetradrachm Thasos Type

The Thasian tetradrachm became a template for Celtic imitators across Thrace and the Danube basin after Thasos resumed striking silver around 148 BC following a Roman-imposed suspension. Celtic workshops copied the type so prolifically — and with such progressive stylistic degradation across generations of die-cutting — that distinguishing early faithful imitations from later abstractions requires close attention to fabric and flan shape rather than design legibility alone. Göbl's classification of these into discrete die classes reflects decades of effort to impose order on what was essentially decentralized, tribal production with no mint authority in any formal sense.
