UNITED NEWS INTERNATIONAL (UNI) — Archaeologists uncovered a trove of Viking Age treasure on a German island in the Baltic Sea.

Hundreds of silver coins and jewelry found on Rügen Island have likely sat untouched since they were buried over 1,000 years ago.

Two amateur archaeologists — one of whom is a 13-year-old boy — were exploring the island with metal detectors in January when they found a single silver coin.

They contacted regional experts who launched a dig on the island and found the treasure in its entirety this past weekend.

They unearthed braided necklaces, pearls, brooches, a Thor’s hammer, rings and some 600 chipped coins.

The oldest coin dates to 714 A.D.

More than 100 of the coins are linked to Norse king Harald Gormsson, better known as “Harry Bluetooth,” who reigned from around 958 to 986 A.D.

He is known for unifying Denmark and introducing Christianity to the country.
