When amateur archaeologist Rene Schön and his 13-year-old sidekick Luca Malaschnitschenko found a shiny piece of metal on a treasure hunt near Schaprode on the German Baltic Sea island of Rügen three months ago, they initially thought they had merely spotted a piece of tinfoil.
But it turned out to be part of the most significant single find of coins and ornaments linked to King Harald Bluetooth (910 - 987). He not only brought Christianity to Denmark in the 10th century, but was also the inspiration for today's Bluetooth technology.
