c. AD 15
The hoard of 840 gold coins discovered here in 2008 is the largest find of Iron Age coins in Britain since the 19th century. Mainly Freckenham-type staters (named after another Suffolk hoard) produced by the Iceni tribe between 20 BC and AD 15. This hoard, a massive 4.58kg of gold, may represent an Icenian royal treasury abandoned perhaps after an invasion by their southern neighbours, the Trinovantes tribe, centred on Colchester.
The hoard is now in Ipswich Museum:
