A detectorist near Sysmä in southern Finland has found the country's largest Viking Age coin hoard: about 4.5 kilograms of silver coins, split between two birch-bark containers.
On 3 September 2026, metal detectorist Kalle Lappinen was searching near the church village of Sysmä, in the Päijät-Häme region of southern Finland, when he found silver coins. The next day, archaeologist Esko Tikkala of Lahti Museums, the regional museum responsible for the area, examined the site and supervised the recovery of the hoard.
The coins had been packed into two containers made of birch bark, placed among stones about 45 centimetres down, roughly 12 metres apart. Some of the birch bark has survived, which is rare, and shows how silver was wrapped for burial. Together the coins weigh about 4.5 kilograms. They are still stuck together, uncleaned and uncounted, but there are thousands of them. With them were a piece of hacksilver, the cut silver traded by weight, a silver arm ring, a silver fitting and a silver bead.
Lahti Museums describes it as the largest Late Iron Age coin hoard known from Finland. The previous record, found at Nousiainen in 1895, held about 1,700 coins and other objects weighing about 2.2 kilograms, so Sysmä is roughly twice the size. Finland's Late Iron Age includes the Viking Age.
The coins now need cleaning and conservation, after which the museum will work out how many there are, where they came from and when the hoard was buried.

Those four are for England and Wales, where the Portable Antiquities Scheme records finds and the Treasure Act decides what must be reported.

The Republic of Ireland is different again, and severely so. Searching for archaeological objects without the Minister’s written consent is a criminal offence carrying fines or imprisonment, and the definition is broad enough to cover coins, buttons and buckles of almost any age.

Northern Ireland is stricter still. The Treasure Act applies and finds go to National Museums NI within fourteen days, but any searching that involves digging — metal detecting expressly included — needs a licence, and licences are only granted for archaeological projects. National Museums NI ›
