A remarkably scarce silver penny minted for King Olaf II Haraldsson has been identified among the Mørstad Hoard, Norway's largest Viking Age coin find. Discovered in eastern Norway in April 2026, the hoard contains around 5,500 coins.
Archaeologist Anne Skogsfjord, cataloguing the collection at the University of Oslo's Museum of Cultural History, first thought the coin was an English penny. Its inscription--"ONLAF R+ NORMANORV," meaning "Olaf, King of the Norwegians"--revealed its Norwegian origin.
A message struck in silver
Made between 1024 and 1028, the penny shows Olaf wearing a pointed helmet. A cross on a stepped base appears beside his portrait, while the reverse features a double cross and an inscription meaning "My leader, my lord." Its style drew on currency from England and Byzantine-inspired Christian symbols.
Fewer than 20 coins issued under Olaf are known to survive, and only four other examples of this particular design have been identified. The University of Oslo's numismatics experts say the coin's imagery linked royal authority with Christianity, presenting Olaf as a ruler connected to wider European traditions.
Olaf, who had been baptized before returning to Norway and becoming king, helped advance Christianity during a period of major religious change. His coins offered a durable way to circulate both his name and Christian symbols. Small cuts on the newly found penny suggest people tested its silver, and researchers estimate it remained in circulation for about 20 to 25 years before being buried with the hoard around 1046 or 1047.
The coin is scheduled to go on display at Oslo's Historical Museum on November 20, 2026. Discoveries like this can help researchers trace how money carried political and religious ideas across communities, enriching our understanding of how societies change.
