If memory serves me right, the Danish coins (Norway) of this period were made of Iron? Harder to find in decent condition w/o rust. I found one in a batch of coins I purchased by the pound recently. Mine is a 1917.
Your coin is a Haakon VII from Norway - by then a separate coinage as Norway was part of the Swedish kingdom until 1905 and not sure why they went with iron vs copper as their source was in Sweden and neither country was in WWI. Have to believe that copper was diverted to both the Allies and Axis - similar to how Sweden played out in WWII.
I bought a 1908-S IHC for 75¢ in 1994. It had dirt on the back, which the dealer didn't remove, so he sold it as a regular 1908. I still have the coin to this day.
