Tetradrachm Herakleskopf Type

The "Herakleskopf" series derives ultimately from Alexander III's silver coinage, which spread across Celtic Europe as trade and mercenary payments carried Macedonian issues far beyond their origin. Eastern Celtic die-cutters progressively abstracted the Macedonian prototypes over generations, dissolving recognizable forms into schematic patterns through a process of stylistic drift that was entirely intentional — Celtic artisans were not failing to copy Greek originals, they were transforming them. The issuing group behind this specific type remains unattributed with any confidence, placing it somewhere within the broad Danubian Celtic sphere.

Kostial 571 and Göbl's Pl. 22 264A/1 represent a fairly narrow die grouping within a much larger, poorly-differentiated series.
