Tetradrachm Eberkopf Type

The "Eberkopf" (boar's head) type belongs to a cluster of Celtic silver issues produced somewhere in the middle Danube basin, most likely by tribes operating east of the Norican sphere. Attribution remains genuinely contested — Kostial, Göbl, and subsequent scholarship have failed to pin production to a single tribal group, which is itself informative: these coins moved across tribal boundaries through gift exchange and mercenary payment rather than through any centralized issuing authority.

Celtic mercenaries serving Hellenistic rulers in the 3rd century BC were frequently paid in Macedonian tetradrachms, which they then imitated locally. The Eberkopf type sits in that tradition of progressive stylistic abstraction away from the Macedonian prototype.
