The Catuvellauni occupied territory north of the Thames — roughly modern Hertfordshire and beyond — and were among the most politically assertive tribes in pre-Roman Britain. Caesar's two expeditions of 55 and 54 BC disrupted but did not destroy their power; Cassivellaunus, their king during the invasions, negotiated terms rather than suffer defeat. These small silver units circulated during and immediately after that period of intense Roman contact, when tribal coinage was still being produced with enough silver content to function as genuine exchange currency rather than the debased issues that came later.
