The Cantii produced the first coins to be actually made in Britain.
These coins were cast in strips which were then cut into separate coins and as a result often retain characteristic cut edges from the runlets which joined them together.

THE CANTII (or Cantiaci)
The Cantii (after whom Kent and Canterbury are named) were the major tribal group in the South East region of England, bordered by the Atrebates, Regni and Catuvellauni.
This region was heavily influenced by continental cultures on the periphery of the early Roman world and this resulted in the Cantii producing the first coins actually made in Britain. These are known as “potins” and they were produced between the mid 2nd to the mid 1st century BC. The earliest versions are known as Kentish Primary, or Thurrock, types. Comparatively the later types, like those from the recently discovered Hillingdon Hoard, are of the “flat linear” type, which uses simplified and abstracted images. Similar coins from the late Iron Age have been found, but in much smaller quantities.
The word “potin” is of French origin and is used to describe these early coins which were cast in clay moulds from a copper alloy with a high tin content. They would have been shiny and silver-coloured when new, and though occasionally examples have turned up which retain this colouration, most coins by the time they get dug up have a characteristic black patina from tin oxidation. These were cast in strips which were then cut into separate coins and as a result often retain characteristic cut edges from the runlets which joined them together. The moulds themselves were made using “master” matrices of copper alloy which were cast with the design for one side of a coin in high relief and pressed into the clay. A rare example of a mould of this type was found a few miles west of the Surrey border in Hampshire.
The designs of the majority of potins found in England derive ultimately from coins produced in the Greek colonial Mediterranean city of Massalia (modern Marseilles) in southern Gaul in the late 4th century BC. These coins featured a head of Apollo on the obverse and a charging bull on the reverse. They were originally imported from the continent and later locally copied in the mid 2nd century BC, in the form of what are known as “Thurrock” types, which adhere closely to the original design. Later forms, known as “flat linear” types, greatly simplified this design into deep abstraction, ultimately reducing the head of Apollo to an outline and the bull to a trapezoidal arrangement of lines
We don’t know what these coins were called by the people who made them, or what they were worth in fiscal terms, but they are generally only found in south east England, which probably reflects the limits of the political and economic influence of the Cantii themselves. It isn't even clear what the role of these Iron Age coins actually was, though it is likely that they assisted in the maintenance of some kind of social power structure. Coins were not generally used as day to day currency by the people of Britain in the 1st and 2nd centuries BC, so apart from any monetary transactions, their range of uses probably included the storage of wealth, use as political tribute, and / or votive objects used as offerings to the gods.
