Rene Schoen and his student Luca Malaschnitschenko were looking for treasure using metal detectors in January on northern Ruegen island when they chanced upon what they initially thought was a worthless piece of aluminium.
Discovered by a 13-year-old boy and his teacher, the find consists of necklaces, pearls, brooches, bracelets, rings and up to 600 silver coins - and some of the treasure has been linked to a famous king who lived over 1,000 years ago.
Experts kept the find secret until a team dug up 400sq metres of land at the weekend.
Harald Gormsson, who was known as Bluetooth because he had one strongly discolored tooth, reigned over what is now Denmark, northern Germany, southern Sweden and parts of Norway from 958 to 986.
In fact, the Bluetooth logo is also derived from the "H" and "B" of his initials. That may offer proof that Bluetooth fled the area to Pomerania after his son, Sven Gabelbart, led a rebellion against him, according to the Telegraph.
The coins found allowed the archaeologists to date the find to the time Bluetooth would have been in the area.
The earliest coin in the Schaprode hoard is reckoned to be a Damascus dirham dating from 714, and the latest ones are Frankish Otto-Adelheid pennies minted in 983.
"We have here the rare case of a discovery that appears to corroborate historical sources,"archaeologist Detlef Jantzen said". They have Christian crosses on them and were given to Danish nobles.
