A rare silver coin minted under the reign of Norwegian king Olaf Haraldsson has just been identified in a huge hoard discovered near the village of Rena, Norway. Known as Olaf the Saint, the ruler, who reigned from 1015 to 1028, is regarded as the country's national patron saint. The hoard, which now contains more than 5,500 coins, has been described as a "national treasure" by the Museum of Cultural History at the University of Oslo.
An exceptional coin bearing the name of Olaf the Saint
According to the Museum of Cultural History at the University of Oslo, fewer than twenty coins struck under the reign of Olaf Haraldsson have ever been recovered. The new coin, which carries his name in Latin letters, is therefore an extremely rare find for historians. It is all the more valuable because Olaf was the first king of Norway to issue coins in his own name, making it a key document for the history of royal power in the early eleventh century.
The coin depicts the ruler accompanied by a cross, while the reverse bears another cross. This design makes the coin a direct witness to the royal will to assert a Christian identity at a time when the country was opening up to the new religion. For numismatists, every iconographic detail matters: it helps date the issues, identify the mints and understand the messages the authorities wished to convey to their subjects.
A coin in the service of Christianisation
Coin specialist Svein Gullbekk of the University of Oslo sees it as a "large-scale Christianisation coin". He explains that Olaf used coinage to legitimise the new faith and to present himself as a Christian king on a European footing, which he aptly describes as "branding". In a society where power was still built largely on warrior alliances and family networks, the image struck on silver became a political tool as effective as any speech.
The king had encountered Christianity during Viking raids in England and France, before being baptised at Rouen around 1013. Having become king in 1015, he proclaimed around 1024 that only Christianity would henceforth be lawful, while many regions, notably around Trøndelag and in the east of the country, remained loyal to the Norse gods. This contrast makes the coin all the more interesting: it shows a power seeking to impose a new religion through symbolic as well as legal means.
The Mørstad hoard, an exceptional discovery
The Mørstad hoard was unearthed in April near the village of Rena. Initially presented as the largest ever found in Norway, it was estimated at nearly 3,000 silver coins. Such a group, buried in the ground, is an exceptional source: it makes it possible to trace the circulation of silver and exchanges during the Viking Age through a single coherent assemblage.
Subsequent research has since revised this count upward: the hoard is said to contain between 5,500 and more than 6,000 coins, according to information reported by the museum. The painstaking inventory, conducted coin by coin, is ongoing and may refine these figures further. Each coin identified adds a data point to the chronology of issues and the geography of exchanges between Norway and the rest of Europe.
A misidentification that led to a discovery
Museum researcher Anne Skogsfjord, in charge of cataloguing, initially took the coin for an Anglo-Saxon penny, a type very common in Viking hoards. It was on reading the inscription that she realised it had been struck in Norway under Olaf Haraldsson. This confusion illustrates how difficult it is to distinguish, with the naked eye, coins from different mints struck a few years apart.
She recounts being overwhelmed by the emotion of that moment, which illustrates the importance of close examination of coin finds, even when the pieces look ordinary at first glance. A hoard of this size can thus conceal exceptional objects that only emerge after patient reading and comparison.
A coin that really circulated
The coin was struck between 1024 and 1028, towards the end of the Viking Age, and then circulated for twenty to twenty-five years before being buried in the hoard. Both faces bear numerous small nicks, a common practice for checking that a coin was entirely silver: by cutting into the metal, the nick revealed any copper core or other alloy beneath.
These marks show that the coin served as a medium of exchange and not merely as a political symbol. Gullbekk believes the king himself determined the appearance of the coins and may have witnessed their minting: "It is quite possible that this coin was held in the king's own hand". The link between coinage, power and everyday life thus becomes very concrete.
