Tetradrachm Y auf Postament Type

Celtic silver coinage of this broad type derives ultimately from the Macedonian tetradrachms of Philip II, which flooded into central and eastern Europe through mercenary payments and trade across the fourth and third centuries BC. The "Y auf Postament" designation refers to a specific schematic reduction of the original reverse charioteer — a stylistic endpoint reached after generations of die-to-die copying progressively abstracted the Greek prototype into something entirely Celtic in character.

Attribution to a specific tribe remains impossible with the evidence currently available. These pieces circulated across a wide corridor from the Carpathian Basin into the Balkans, and find-spot evidence alone rarely narrows the issuer.
