A metal detectorist in Finland has discovered what is described as the country’s largest Viking Age silver hoard. Initial reports say the find includes thousands of silver coins and additional silver items, including jewelry, and is located north of Helsinki.

The hoard is reported to be an Iron Age/Viking Age cache, but its full scope and authenticity are still being assessed by authorities and experts. Gizmodo notes that, based on the amount of silver alone, the material could be valued at nearly $10,000 in today’s terms by weight, though that estimate is not a finalized valuation. Live Science focuses on the scale and composition of the hoard, emphasizing the large number of coins and jewelry pieces. The question of how the hoard came to be buried—such as whether it reflects plunder versus other circumstances—remains under examination as the inventory and context are studied.
