In 2009, an amateur with a metal detector went to a field in Staffordshire, England, and found a “hoard,” about 3,500 fragments, of Anglo-Saxon gold. Archaeologists are still excavating and finding more pieces. Late last year, two metal-detecting friends who, for years had decided to fish instead of hunt for metal, decided to try searching again. They found a new hoard of Iron Age gold jewelry. There were four gold pieces called “torcs” — three collars and a bracelet of twisted gold wire with a finial at each end. They were made about 400 to 250 BC, possibly the earliest Iron Age gold ever found in Britain. The find may change the pre-Roman history of Britain. The finders get a reward.
