A British Metal Detectorist has discovered and reported an immensely important hoard of Viking era coins and silver artifacts. See http://www.telegraph.co.uk/culture/culturenews/8955955/Viking-hoard-provides-new-clues-to-previously-unknown-ruler.html and http://finds.org.uk/news
The hoard contains a coin of a previously unknown ruler as well as coins from from far off Germany and the Middle East. More proof that even in the "Dark Ages" coins travelled long distances from their place of manufacture.
Although archaeological cranks may still find reason to criticize the Treasure Act and Portable Antiquities Scheme and the cooperation if fosters among members of the public, archaeologists, and museum professionals, how many such hoards are voluntarily reported in their preferred models of cultural heritage management such as Greece, Egypt, Turkey, Italy and Cyprus?
