1⁄24 Stater Athena Alkidemos Type

The Boii were among the most powerful Celtic tribes in temperate Europe until Rome and migrating Germanic peoples dismantled their territory across the 2nd and 1st centuries BC. Their coinage derived ultimately from Macedonian prototypes absorbed during Celtic mercenary service, then progressively abstracted through generations of local die-cutting. By the time fractional issues like this one were being struck, the original Hellenistic source material had been reduced to near-geometric forms — a process of stylistic drift that happened deliberately, not through ignorance.

The Kostial corpus remains the primary reference for Boian gold fractions. At 0.29g, these pieces served precise transactional needs in a monetary system that operated alongside barter and tribute.
