It’s a nice commemorative! But yours is the 100 kroner, celebrating Olav Vs 25 year jubilee as king. The 25 kroner is broader, actually dollar sized, with both Haakon and Olav on obverse and a V for victory on reverse:
Let’s look at that coin from todays monetary perspective: 25kr =2.1$ Todays silver price; 14.8 $ (good luck getting physical silver for that) Approximate silver value for the 25 kr is 13$ or about 150 kroner. I’m holding on to my prescious metals for sure.
Thanks. When i got this collection all the norwegian coins were in folders. Never slid them out to look at them before and in the plastic sleeves with light bouncing off you don't really appreciate what they really look like. If i find more with toning like that i will post them
