German Otto Adelheid penny

This coin is a German Otto Adelheid penny found in a Viking Age hoard in Tuomola, Raisio, in 1835. The coin was struck in the name of King Otto III, who came to power as a minor, and his regent, his grandmother Adelaide (dated 983–1002). On the front of the coin is a cross with the letters O-D-O-D in the corners. On the back is a wooden church with a dot inside it and a horizontal bar at the bottom. Otto Adelheid pennies were struck in Saxony, and they are the most common type of Viking Age coins found in Finland and Sweden. Otto Adelheid pennies were produced in huge numbers in various mints, and the main minting location was probably Goslar. Some of the coins may have also been struck in Quedlinburg and Hildesheim. Otto Adelheid pennies were later imitated until around 1050. The objects found in the hoard in Tuomola, Raisio had been hidden sometime after the mid-11th century.
