Denarius

The Eravisci were a Celtic tribe settled in Pannonia, in the region around modern Budapest, whose coinage closely imitated contemporary Roman Republican denarii — so closely, in fact, that their issues long went unrecognized as local imitations rather than Roman mint products. The copying was deliberate and functional: Roman silver circulated heavily in the region, and a coin that looked Roman passed without friction in cross-cultural trade.

Stylistic drift between the Roman prototype and the Eraviscian copy is the primary diagnostic, with legends often garbled or compressed by die-cutters working from visual templates rather than literacy in Latin.
