Drachm Prague type

The Boii were expelled from their Bohemian homeland by the Marcomanni around 50–60 BC, making the later end of this coin's date range something of a scholarly formality — production almost certainly collapsed with the tribe's displacement. The Prague type takes its name from findspot concentrations around the Bohemian basin, where hoards have provided the bulk of typological study. These are Celtic staters reduced through successive weight debasement to a fraction coinage, the shrinkage in both size and silver content tracking the Boii's increasingly pressured political circumstances across the final century BC.
