The piece—named Crosby Garrett for the hamlet in Cumbria where it was found—sold for nearly eight times the amount it was expected to fetch. Six persistent bidders pushed the price up in auction, according to the Associated Press.
Aitken described the find as "the discovery of a lifetime for a metal detectorist."
"When it was initially brought to Christie's and I examined it firsthand, I saw this extraordinary face from the past staring back at me and I could scarcely believe my eyes," the AP reported Aitken as saying.

Just for Show
A profile of the Crosby Garrett helmet is seen in an undated photo released by Christie's in September.
Christie's describes the nearly 2,000-year-old artifact as a cavalry parade helmet, worn for sporting events rather than for combat.
