Archaeologists in Finland are examining the country’s largest known coin hoard from the late Iron Age after a metal detector enthusiast discovered about 4.5 kilograms, or nearly 10 pounds, of Viking-era silver. The remarkable cache contains silver coins and other silver objects. They were packed inside two containers made from straw and buried only a few dozen centimeters below the surface.
Researchers have not yet cleaned, separated or counted the objects. The exact number of coins, their weight and the date of the hoard will be determined through further study.
Metal detectorist uncovers buried silver
A metal detector enthusiast discovered the treasure last week. Archaeologists investigated the site the following day under the direction of Esko Tikkala, an archaeologist with Lahti Museums. The preliminary weight of the entire find is about 4.5 kilograms. Researchers cautioned that the figure could change after specialists clean and examine the objects.
The discovery adds Finland to a growing list of major Viking treasure finds across northern Europe. In April, archaeologists recovered nearly 3,000 Viking silver coins from a record hoard in Norway. More recently, a homeowner in Denmark uncovered the country’s largest known Viking silver hoard, weighing 18.5 kilograms.
Discovery breaks a record more than a century old
The Finnish cache appears to be significantly larger than the country’s previous record Viking Age hoard, discovered more than 130 years ago. That treasure was found in 1895. It contained about 1,700 coins and other objects weighing approximately 2.2 kilograms, or nearly 5 pounds.

The newly discovered cache weighs roughly twice as much, according to the preliminary measurement. Its full significance, however, will become clearer only after conservation and detailed analysis.
Coins could reveal wider Viking trade connections
The silver could offer new evidence about trade, wealth and movement during Finland’s late Iron Age. Viking trade networks stretched far beyond Scandinavia. Norse traders traveled east through waterways connecting the Baltic with the Black and Caspian seas. Silver was particularly important in these exchanges. Vikings prized silver coins from the Islamic world, while trade routes eventually brought Scandinavian travelers into contact with the Byzantine Empire and Constantinople.
Researchers will now examine the newly discovered Finnish coins for inscriptions, designs, and other details that could reveal where they were minted. Such evidence could help establish when the treasure was buried and how far the silver traveled before reaching Finland.
For now, archaeologists face the careful task of separating and conserving the material without damaging the coins or other objects. Once that work is complete, researchers should be able to establish how many artifacts the two straw containers held, where the silver originated, and when someone buried what has become Finland’s largest known late Iron Age coin cache.
