This coin will be published in a future article in the SENA journal. In it the authors argue that, as typical of issues after the Gallic Wars, this coin's types are influenced by Roman Republican issues. The obverse is likely inspired by a denarius of Sextus Pompey struck circa 37/6 BC, featuring the diademed, bearded head of Neptune (Crawford 511/2b), while the reverse may be inspired by a denarius of Cn. Plancus struck circa 55 BC, featuring a Cretan goat (Crawford 432/1). Based on a variety of factors, they place the issue somewhere in the Bourges region.
