A hobbyist metal detectorist searching the woods near his hometown has uncovered what archaeologists call Finland’s largest Viking Age silver coin hoard, a cache of thousands of coins and jewelry weighing roughly 4.5 kilograms (about 10 pounds) that more than doubles the country’s previous record.
Kalle Lappinen, 40, a merchant navy officer who also deals in antique tiled stoves, made the discovery on September 3, 2026, while detecting near the church village of Sysmä in the Päijät-Häme region, about 150–170 kilometers northeast of Helsinki. He had searched the wooded area before without success. When his detector signaled, he dug carefully through soil, moraine, and cobblestones. His handheld pinpointer then “roared.” About 45 centimeters (18 inches) underground he found a pile of silver coins packed in the remains of a birch-bark container.
After recovering from the initial adrenaline, Lappinen reported the find immediately to antiquities authorities. His detector soon signaled again nearby, revealing a second deposit roughly 12 meters (about 39–40 feet) away, also buried among stones in a birch-bark container. “First came a little disbelief, then the adrenaline and the feeling of success,” Lappinen later told Finnish broadcaster Yle. “The work paid off again.” He has expressed pride that the discovery underscores Sysmä’s significance during the Viking Age.
The following day, archaeologist Esko Tikkala of Lahti Museums, the regional body responsible for archaeological heritage, inspected the site and supervised recovery of the material. In addition to the thousands of silver coins (estimates in some reports exceed 4,000; exact numbers await full cleaning and separation), the hoard includes a fragment of hacksilver, a silver bracelet or bracelet fragment, a silver fitting or clasp, and a silver bead.
The total weight of the coins alone is approximately 4.5 kilograms. They have not yet been fully cleaned, separated, or counted, so precise figures and more refined dating will emerge from ongoing study. Preliminary assessment places the material between about AD 1000 and 1050, at the close of the Viking Age and within Finland’s Late Iron Age.
The coins reflect far-reaching trade networks of the era. They include pieces from Sweden, present-day Britain and Germany, as well as Islamic dirhams originating from regions corresponding to modern Turkey and Iran. Hacksilver—cut fragments used as bullion for payments by weight—further illustrates the period’s silver-based economy.
Frida Ehrnsten, keeper of the numismatic collections at the National Museum of Finland, has described the arrangement as a rare “double hoard.” “We haven’t really had any known examples of those from before,” she said. She called the discovery “a very, very, very important new find that will in some ways probably change our perception of the Viking Age silver economy here.”
Until now, Finland’s largest known Viking Age coin hoard was the 1895 Nousiainen find, which contained roughly 1,700 coins and other objects totaling about 2.2 kilograms. The Sysmä discovery roughly doubles that scale.
This one blows past Finland’s previous record, a 1895 hoard from Nousiainen that held about 1,700 coins and weighed half as much. Local archaeologists note that Sysmä and the surrounding area seem to have been a hotspot for burying valuables during unsettled times. No graves were found with the silver, so the leading theory is that someone stashed it for safekeeping and never came back.
Finland wasn’t Viking territory in the strict Scandinavian sense, but the region had plenty of contact across the Baltic. Lappinen, for his part, seemed pretty thrilled that his hometown just got a bigger place on the historical map. “It was extremely nice to prove with this hoard that my hometown has been something really special during the Viking Age,” he said.
The material is now with the museums for cleaning, cataloguing, and closer study. Whatever the final count turns out to be, it’s already the biggest silver score of its kind Finland has ever seen — and it started with one guy and a metal detector on a regular Thursday afternoon.
