Dirty 'button' unearthed by metal detectorist turns out to be a rare 900-year-old coin from Norway's last Viking king, Magnus Barefoot
A rare coin from the reign of Magnus Barefoot โ sometimes called Norway's last Viking king, was mistaken for a button before researchers realized it was the first of its kind found on Norwegian soil.

The discovery of a Magnus Barefoot-era coin in Norway isnโt just a numismatic triumphโitโs a tangible link to the final decades of Viking expansionism, when Scandinavian rulers navigated shifting alliances between the British Isles, the North Sea, and continental Europe. For historians, this artifact challenges assumptions about Norwayโs late Viking period as purely insular, instead revealing the extent of Magnusโs influence in trade and diplomacy across northern waters.
Background Context
Magnus Barefoot (reigned c. 1093โ1103) ruled during a transitional era in Norse history, when the Viking Ageโs raiding ethos gave way to structured statecraft, yet the crown still relied on maritime power and tribute networks. His reign saw Norwegian expeditions to the Hebrides and the Isle of Man, but archaeological evidence of his rule within Norway itself has been scarceโuntil now. The coinโs provenance suggests Oslo or the Oslofjord region as a key hub in his administration, far from the traditional Viking strongholds of the west coast.
What Happens Next
This discovery will likely prompt renewed metal-detecting surveys in southeastern Norway, particularly in areas tied to Magnusโs itineraries, potentially uncovering further evidence of his administration. Researchers may also revisit early medieval trade records to reconcile this coinโs presence with historical accounts of barefootโs economic policies. For Norwayโs cultural heritage sector, it underscores the potential of non-invasive archaeology in uncovering lost national treasures.
Bigger Picture
This find aligns with a broader pattern of metal-detecting rediscoveries across Europe, which are reshaping our understanding of medieval economies and state formation. It also highlights how decentralized discoveryโvia amateur archaeologistsโcontinues to fill critical gaps in official records, particularly in regions where Viking-era sites were long overshadowed by later medieval developments.
