The Coroner is responsible for enquiries into Treasure finds.
Report a find
If you find any item that could be defined as treasure, you must report it to the Coroner within 14 days. It is a criminal offence not to do so.
Find investigations and inquests
The Coroner will contact the relevant body to investigate your find. If your object is confirmed by The British Museum as Potential Treasure, the Coroner will hold an inquest to decide whether to declare it “Treasure”.
The central government website GOV.UK gives further information on treasure finds.
Unfortunately there aren’t any upcoming inquests.
