Penny

 

 Pennies from Olav Tryggvason to Erik Magnusson 

 

Pennies were minted in Norway from the reign of Olav Tryggvason (995-1000) to that of Olav Håkonsson (1380-1387). This was the dominant coin unit in Norway in the Middle Ages. The Old Norse system of weights included the following units of weight: ertog, øre and mark. There were ten pennies to an ertog, 30 pennies to an øre and 240 pennies to a mark.

The standard for the penny changed several times through the Middle Ages. The motif, inscriptions, size, weight and silver content could vary significantly.
