One of the largest collections of Roman coins -- over 30,000 silver pieces -- has been recovered in England from the building site of a new hotel in Bath, just 450 feet from the historic Roman Baths.
Known as the Beau Street Hoard, from the street where they have been unearthed, the coins date to 270 A.D., a time of great upheaval when the western Roman empire was threatened by civil war and barbarian invasion.
Aware of the difficult times, the owner might have just decided to hide away the treasure.
If war comes, you can't go along with 30k coins.
In ancient times, it didn't matter wether troops were officially "friendly" or not, they usually plundered and raped anyway.
So hiding it and coming to get it later was better and these people probably never came back because they got killed or enslaved.
But 270 is more roman infighting than anglo-saxon invasion.
