Tetradrachm Samobor A Type

East Noricum occupied the eastern Alpine region roughly corresponding to modern Slovenia and parts of Austria, and its Celtic tribes produced coinage in the late La Tène period largely to facilitate trade and mercenary payments rather than any centralized fiscal administration. The Samobor group takes its name from the Croatian town near whose surroundings a significant concentration of these pieces has been found — a distribution pattern suggesting the Kolpa River valley served as a commercial corridor between Norican and Pannonian tribal territories.

Kostial 158 sits within a typological cluster distinguished by progressive abstraction of the prototype, almost certainly a Macedonian or Thasian tetradrachm filtered through several generations of Celtic die-cutters.
