St Albans Hoard

The St Albans Hoard is a large hoard of late Roman gold coins found by a metal detectorist in a field near St Albans, Hertfordshire, England in 2012. It is believed to be one of the largest hoards of Roman gold coins ever found in Britain. The hoard consists of 159 solidi dating from the last decades of the fourth century AD, near the end of the Roman occupation of Britain. After about 408,^[1] new Roman coins ceased to circulate in Britain, causing the collapse of the monetary economy and of mass-production industry.^[2][3]
