1/4 Stater Regenbogenschüsselchen Type

The Vindelici occupied what is now southern Bavaria and parts of Austria, and their coinage — including this fractional stater — circulated widely across the Celtic oppidum network that stretched from the Danube to the Alps. The "rainbow cup" designation comes from post-medieval Bavarian farmers who found these convex gold pieces in their fields after rain, believing them to be solidified fragments of rainbows.

The specific Kostial 6 reference places this among the earlier die studies of the type. Hoards like those from Großbissendorf have helped establish the chronology of Vindelician fractions, though precise dating within the two-century production window remains contested.
