Tetradrachm Philip III Type

Philip III of Macedon — half-brother to Alexander the Great, intellectually disabled, and installed as a puppet king by the Macedonian army in 323 BC — died by assassination in 317 BC, yet his coinage circulated and was copied across the Celtic world for well over a century after his death. These eastern Celtic imitations spread through a process of stylistic drift: each generation of dies copied the previous generation's coins rather than the originals, producing progressively more abstract results that retain little of the Macedonian prototype beyond the basic compositional structure.

The attribution to "uncertain eastern European Celts" reflects genuine scholarly disagreement — the production zone likely spans the middle Danube basin, but die studies have not resolved a more precise origin.
