The discovery was made by 11 years old Maja Sielska, who diligently did her school homework about the Middle Ages. While looking through pictures of coins from this period in the textbook and on the Internet, the girl saw a plate with mysterious inscriptions similar to the one she had received from her grandmother. The schoolgirl showed her family heirloom to her teacher, who in turn passed it on to researchers. Its estimated value is around €1 mln (£793,145)
A small gold plate belonging to a Polish family Sielscy from the Swedish Malmoe turned out to be an archaeological sensation. According to the researchers, it is probably a souvenir from the funeral of the Danish King Harald Bluetooth on the island of Wolin, dated to c. 986 AD.
