The Third Coinage introduces thoroughly Romanized designs to the silver and bronze. No distinguishing privy mark identifies the series consistently, though the gold and silver have a pronounced pellet-in-ring motif in the field. The Third Coinage's quarter stater awaits discovery.
Vosenos, a short-lived ruler, issued a single coinage. Most of his types are known in only a handful of examples. On the gold, the banding, seen only slightly on the coinage of Dubnovellaunus, becomes pronounced.
Sometime during the Trinovantian/Catuvellaunian Interregnum, Vosenos disappears and the Atrebatic/Regnan/Belgic ruler Eppillus appears. Eppillus issues a special coinage for use in Kent, including a Victory stater. These coins have traditionally been ascribed to an invasion – one with a traveling mint following the invaders.
Eppillus' occupation of Kent appears to have been short-lived. Coins of Cunobeline soon replace them, suggesting Cunobeline drove Eppillus out. Cunobeline's coins become the normal coins of Kent for the next thirty years.
For the coins of Eppillus in Kent, refer to the coinage of the Atrebates/Regni/Belgae, 430-01 to 453-01. The coins of Cunobeline which circulated in Kent are the normal Trinovantian/Catuvellaunian issues.
Towards the end of Cunobeline's reign, new types appear in Kent carrying the inscription Amminius or AM.
Amminius' Second Coinage is cruder in execution than the First. The coins are characterized by a Capricorn on the reverse. These are the last Celtic coins struck in Kent, on the eve of the Claudian invasion. A silver minim with an 'A' in an eight-sided star and bird reverse, traditionally assigned to Amminius is actually a coin of Verica (561-01) – a type-series of these was found in the Wanborough Hoard.
The first inscribed coins carry an illegible inscription, mostly off the flan on existing pieces. The letters 'IVII' partially appear on one stater, but the reading is uncertain. Hopefully, future finds will enable the full inscription to be read.
The next series of inscribed coins are those of the Kentish Dubnovellaunus, probably a different ruler from the one in Essex. Dubnovellaunus-in-Kent struck coins from about 30 B.C. up to the Trinovantian/Catuvellaunian Interregnum, about 10 B.C. At this point, he was replaced by a short-lived ruler, Vosenos, who was in turn replaced by Eppillus of the Atrebates/Regni/Belgae. Eppillus, sensing a loss of Trinovantian/Catuvellaunian influence, intervened in Kent only to be later driven out by Cunobeline. Eppillus issued special coins for use in Kent; subsequently, Cunobeline's coinage circulated. Between the death of Cunobeline and the Claudian invasion, the brief issues of Amminius appeared.
All Kentish dynastic coinage is extremely rare, with only a few examples of each type known today. The issues must have been small, and would be relatively unimportant except they identify the names of Kentish rulers. For the most part, the economic influences of the Trinovantes/Catuvellauni, and for a short time the Artebates/Regni/Belgae were the significant factors in Kent.
