In 2010 a young detectorist in Cumbria found a Roman cavalry helmet with a face mask, in dozens of pieces. Because the law did not count it as Treasure, it was restored and sold at auction for about £2.3 million to a private collector.
In May 2010 a metal detectorist in his twenties, who has never been named, was searching pasture near the village of Crosby Garrett in Cumbria, not far from Kirkby Stephen, when he found the pieces of a copper-alloy helmet about 25 centimetres down. He had been detecting in the parish with his father for several years.
It was a Roman cavalry sports helmet, made in two parts: a cap of curly hair topped by a griffin, and a face mask showing a clean-shaven young man. Helmets like this were worn for parades and display, not for battle. It seems to have been folded before it was buried, and it came out of the ground in 67 fragments. Specialists date it to the late 2nd or early 3rd century AD, though the auction house described it as earlier.
Because it was a single object of copper alloy, not gold or silver, it did not count as Treasure under the Treasure Act. There was no legal duty to report it and no right for a museum to acquire it. The finder did tell the Portable Antiquities Scheme, and in August 2010 two finds liaison officers visited the findspot with him and recorded it. By then the pieces were with Christie's, which had the helmet restored for sale despite requests from the British Museum and the Portable Antiquities Scheme to wait until it could be examined. Evidence about how it was made and buried may have been lost in the process.
At Christie's in London on 7 October 2010, against an estimate of £200,000 to £300,000, it sold for about £2.3 million to an anonymous private collector bidding by telephone. Tullie House Museum in Carlisle, backed by the British Museum, had raised £1.7 million with help from the National Heritage Memorial Fund, the Art Fund and the public, and was outbid.
Excavations at the findspot afterwards found a Romano-British farming settlement that nobody had known about, and a stone structure that may have marked the place where the helmet was buried. The owner has lent it to exhibitions at the Royal Academy, the British Museum and Tullie House, but it remains in private hands.

Those four are for England and Wales, where the Portable Antiquities Scheme records finds and the Treasure Act decides what must be reported.

The Republic of Ireland is different again, and severely so. Searching for archaeological objects without the Minister’s written consent is a criminal offence carrying fines or imprisonment, and the definition is broad enough to cover coins, buttons and buckles of almost any age.

Northern Ireland is stricter still. The Treasure Act applies and finds go to National Museums NI within fourteen days, but any searching that involves digging — metal detecting expressly included — needs a licence, and licences are only granted for archaeological projects. National Museums NI ›
