Tetradrachm Kroisbach-Reiterstumpf Type

The Kroisbach-Reiterstumpf group takes its name from the Kroisbach hoard found near Wiener Neustadt, Austria, which yielded a concentrated deposit of this type and anchored its classification. Attribution to a specific tribe remains unsettled — the issuing authority is somewhere within the middle Danubian Celtic sphere, but the distribution evidence doesn't resolve it further than that. These tetradrachms derive ultimately from the Philip II Macedonian prototype, degraded across generations of local copying until the figural elements dissolved into abstraction.

The "Reiterstumpf" designation — roughly, rider-stump — refers to the progressive stylization of the horseman reverse into something barely recognizable as figurative at all.
