Bracteates from the time of Olav Håkonsson and Håkon Håkonsson. 


Bracteates were struck on one side only. The blanks were so thin that the pattern was visible on the reverse as a negative design. The word bracteate refers to the production method, but it is usually associated with a particular monetary unit (pennies were double-sided coins, for example, while quarter-pennies were bracteates in the 1200s). 

This medieval method of striking coins was probably first used in German regions and the method reached Norway very early. Here, bracteates were introduced from approximately 1110. Later, King Sverre minted large numbers of bracteates, these being the lightest coins we know of, weighing as little as 0.06 grams. In Norway, the last bracteates were minted in the period 1510-1522, by Archbishop Erik Valkendorf.
