The "Entenschnabel" — duck's bill — designation refers not to a design element but to the distinctive shape of the planchet's edge, a warping artifact that results from the hammering technique used by Celtic die-cutters working without the standardized blank preparation methods of Mediterranean mints. These coins are among the most difficult Celtic issues to attribute with confidence; "Uncertain Eastern European Celts" is less a classification than an admission of ongoing scholarly disagreement about which tribal group or groups produced them.
The Kostial and Göbl references anchor this type within a broader typological tradition derived from Macedonian prototypes, but the copying process had by this period diverged so far from its source that the lineage is traceable only through die study.
