A group of hobby metal detectorists discovered a hoard of Viking silver near the ruins of the Viking castle Fyrkat, in Hobro, North Denmark.

The trove contained over 300 items, including Danish, German and Arab coins, as well as silver balls, and a ring pin.

The find — made in autumn last year — dates back to the 900s, when King Harald “Bluetooth” (Blåtand) Gormsson, who united Denmark and Norway. His nickname, the result of a prominent dead tooth, inspired the widely used wireless technology between electronic devices, according to The Viking Herald.

[I never catch fish and I never find anything cool. As children, we sat in a sweltering diamond field in Murfreesboro, AR for days in the 60s – one of my whacko parents’ ideas of a “family” vacation – never found a thing. Trio of teenagers chasing each other around next to us. One tripped, she got up out of the dirt, looked back down…3 or 4-carat diamond. Even my Daddy, the most optimistic of creatures, said, “That’s it. Let’s go.” ~ Beege]
