A "nationally significant" hoard of Roman gold coins has been found by a metal detectorist in Hertfordshire.
The stash - found on private land north of St Albans - is believed to be one of the largest Roman gold coin hoards discovered in the UK.
The 159 coins date to the end of the 4th Century during the final years of Roman rule in Britain. After AD 408 no more coin supplies reached the country.
The value of the hoard has not yet been assessed.
A team from St Albans City and District Council museums' service investigated the site at the beginning of October to confirm the find.
