Age dating of a coin
The guide gives you access to over 41,000 examples of Iron Age coins with around 40,000 images of various resolutions.
All four named issuers have a coin distribution centred on Essex/Hertfordshire and north Kent with pieces also found in Oxfordshire, Northamptonshire and East Anglia (Cunliffe 1981).
The assemblage was examined after cleaning work (the extent of which was decided through discussion with the conservator) and analysis of X-rays.
The vast majority of coins found were low value copper-alloy and potin (a tin-rich copper-alloy) coins, accounting for 92% of the total.
Some coins (mostly earlier issues) are uninscribed.
However, as time passes, more inscribed coins are struck.
