Claudian imitatives tend to be from
Spain,
Britain and northern
France. Not sure if earlier (Augustan - Tiberian) follow that same pattern or not.
Stylistically the
obverse, especially the ring of fairly large dots, looks like the Augustan local coinage of
Spain. Especially that of Iulia
Traducta which are often found very crude and off centre. They are roughly
contemporary with Augustus' SC
types.
For Claudian imitations there are several
good articles plus the
Banti volume (
CNR XV) is
very good. I don't have the Augustan era
Banti volume(s) to know if they cover imitations well or not.
