"Constructed of sheet iron, the helmet, once decorated with gold leaf, is the only one to have been found in Britain with its silver gilt plating intact." Source: Telegraph.
"The helmet features scenes of Roman military victory, including the bust of a woman flanked by lions, and a Roman Emperor on horseback with the goddess Victory flying behind and a cowering figure, possibly a native Briton, being trampled under his horse's hooves.
"The object is believed to have been buried in the years around Roman Emperor Claudius's invasion of Britain in AD43." More here.
