Rare Roman Helmet

From National Geographic:

A rare Roman helmet dating to the late first to second century A.D. fetched nearly $3.6 million dollars at a London auction on October 7.

The bronze helmet and face mask was discovered in May 2010 by a treasure hunter using a metal detector in a field in Cumbria, a county in northwestern England.

The helmet was described by Christie's auction house as "an extraordinary example of Roman metalwork at its zenith."

Both the sellers and winning bidder have remained anonymous.
