later,  perhaps the indirect consequences of, say, the German campaigns of  
Augustus, the provincialisation of  Gaul or Augustan diplomacy.
This reading of  the continuity of  the archaeological evidence was under-
standable. However, it overlooked a series of  radical changes that can be 
seen in the coinage, which suggest a signifi cant alteration in the symbolic lan-
guage of  political authority, even if  that did not lead to any immediate shift 
in the day-to-day patterns of  existence for the majority of  the population. 
Three totally independent transformations can be seen in the numismatic 
record, each of  which suggests there was a large-scale political change within 
(or imposed on) southeast Britain in the mid fi rst century BC (Creighton 
2000: 55–74). The imagery on the coinage changed, their metallurgy and 
colour changed, and these new issues totally replaced all preceding coins in 
circulation.
Gold coin had already been circulating in quantity in southeast Britain for 
perhaps a century, with some types of  coin having a distribution area on 
both sides of  the English Channel. The imagery had been remarkably con-
servative, with successive issues mimicking earlier ones, but slightly altering 
the abstracted design on each occasion of  what had originally been a head 
on one side and a horse on the other. However, in the mid fi rst  century 
BC there was a break in that lineal continuity, and two new series emerged 
(called British L and British Q). While the image still had an abstract face 
on one side and a horse on the other as earlier issues had done, the nature 
of  that abstraction was different from the existing coinage in Britain. In an 
aesthetic system where incremental change dominated the visual language, 
this alteration would have been very obvious. Instead of  adapting a local 
coin type, these new series owed a lot in their design to a continental coin 
(Gallo-Belgic F) which had circulated in the region of  the Aisne valley in 
northern France, traditionally ascribed to the tribe of the Suessiones. Both 
new coin types can be seen to be the founding issues of  two new dynasties. 
As British L developed in the east it began to be inscribed with the names of  
rulers such as Tasciovanus and Cunobelin. As British Q came to dominate 
the south, it was marked with the names of  another dynasty, starting with 
Commius and  Tincomarus. So the mid fi rst century saw the emergence of  
dynastic coinage – in each case replacing earlier series with a new form of  
imagery. It appears as though something of  genuine political signifi cance had 
happened. This view is reinforced by two other numismatic observations.
The second change we see is a transformation at the same time in the gold 
content of  these new series. In antiquity few objects were made of refi ned 
gold; most were ternary alloys of  gold, silver and copper, all of which had 
slightly different colours. Whereas the earlier coins had a yellowy hue with 
a fairly variable gold content, the new series were now made of a red-gold 
alloy, which had a far more stable proportion of  gold in it. The difference in 
tone is very noticeable if  any coins are seen side by side in a museum. This, 
again, signifi ed change, not only visually in terms of  colour, but perhaps also
