Tetradrachm Zweigarm Type

The "Zweigarm" — literally "two-arm" — designation refers to a specific die classification within the sprawling Philip II imitation coinage that Celtic tribes across the Danubian basin produced for well over a century. Attributing these to a precise issuing group remains genuinely contested; the eastern Celtic monetary sphere was decentralized, with individual tribes or confederacies striking their own interpretations without coordinated authority. Kostial's numbering system remains one of the more useful organizing frameworks, though Göbl's die studies revealed just how many distinct workshop traditions were operating in rough parallel.
