This Iron Age copper alloy coin is a denomination known as unit.

Coins of this age are prone to heavy wear, yet this example is very well-preserved, with unusually sharp detail remaining. The coin was issued by a mint associated with Cunobelin, historically attested to be the ruler of both the Catuvellauni and Trinovantes tribes.

The obverse of the coin bears the legend CUNOBELINUS, with the helmeted head of Cunobelin dividing it into two parts (CUNO is missing). The reverse depicts a female pig, or sow, with the legend TASCIIOVANIIF. The style of the coin imitates continental Roman coinage and dates to the period AD 10 to AD 40.
