A metal detectorist in Finland unearthed more than 4,000 Viking Age silver coins and fragments split across two separate caches near Sysmä. The September 3 discovery shatters a 131-year-old national record for silver hoards, yielding roughly 10 pounds of precious metal from deposits buried about 39 feet apart.
An ordinary afternoon of treasure hunting turned up the largest Late Iron Age silver find in Finland’s history when hobbyist Kalle Lappinen swept a field in the southern church village of Sysmä, a town about 105 miles northeast of Helsinki. Lappinen caught a signal on September 3 that sounded unlike anything he had encountered before, digging down about a foot and a half into a compacted mass of metal glued together by centuries underground. Not far away, his machine screamed over a second stash.
The discovery eclipsed Finland’s previous record holder, an 1895 haul unearthed in Nousiainen that contained about 1,700 coins and weighed roughly 2.2 kilograms. The Sysmä hoard more than doubles that coin count and tips the scales at approximately 10 pounds of silver, according to regional museum officials.
Excavation and the Double Hoard Mystery at Sysmä
Lappinen promptly reported his discovery to authorities on the day he made it. Archaeologists from Lahti Museums arrived the following day, September 4, to supervise the recovery led by archaeologist Esko Tikkala. Investigators found that the silver had been packed into two separate birch-bark containers wedged between stones about 45 centimeters below the surface. The containers rested roughly 12 meters, or 39 feet, apart.
Frida Ehrnsten, keeper of the numismatic collections at the National Museum of Finland, noted that finding two distinct caches so close together is unprecedented in the region.
“It’s kind of a double hoard. We haven’t really had any known examples of those from before.”

Traces of the birch-bark packaging survived in Finland’s typically acidic soil, offering researchers rare organic clues about how the treasure was bundled before burial. Aside from thousands of silver coins, the excavation yielded a silver arm ring, a decorative clasp, a silver bead, and a fragment of hacksilver—silver cut into pieces and used as currency by weight.
Global Trade Networks Reflected in Coins From Sweden, Britain, and the Islamic World
Preliminary dating places the hoards between 1000 and 1050 A.D., capturing a bustling era of medieval commerce. The recovered currency spans multiple territories, featuring coins minted in Sweden, Britain, and German territories that once belonged to the Holy Roman Empire. The most distant travelers in the collection are dirhams originating across the Islamic world, likely struck in areas that are now Turkey and Iran.
Scholars emphasize that these Islamic coins moved into Scandinavia along trade routes traversing Russia and the Baltic rather than necessarily through raiding. Tikkala observed that the sheer volume of wealth shifts modern perspectives on Sysmä’s historical footprint.
“Today, Sysmä might be regarded as a relatively modest and peripheral place, but judging from the Late Iron Age archaeological material, the situation seems to have been very different a thousand years ago.”

Because no bones or graves turned up near the site, researchers believe the silver was stashed for safekeeping. Tikkala suggested two leading possibilities: a traveling merchant burying a portion of his wealth to travel light, or a local inhabitant concealing valuables amid the threat of conflict. Why the owner never returned to retrieve the double hoard remains unknown.
Finnish Antiquities Law and the Payout Wait for Finders
Under Finland’s Antiquities Act of 1963, any archaeological object more than a century old automatically becomes state property. Lappinen cannot keep or sell the coins, and the Finnish Heritage Agency holds formal custody of the recovery.
However, Finnish law compensates finders of precious metal objects through a statutory redemption price calculated from the market value of the metal plus at least 25 percent on top. Bullion estimates for the raw silver alone approach $10,000, though a final valuation will include an archaeological premium once experts finish cleaning and weighing the clumped coins. Finding the payout will require patience, as collection moves and a nationwide surge in metal-detecting reports have created a processing backlog of roughly three years for redemption cases.
