A bit more information about the Lillehammer set (we actually had a commercial here, with George Clooney trying to pronounce Lillestrøm. Equally funny as Arnold saying Lillehammer, I guess).
The Lillehammer set was, as expected, issued in the three years before the Winder Olympics took place in 1994: 1991 to 1993. This was the most ambitious set of commemorative coins released in Norway so far (and still is). Every year, 2 sets of 2 silver coins (50 NOK (half troy ounce of silver) and 100 NOK (one troy ounce of silver)) were released, as well as at least 1 gold coin (half troy ounce each). The small coins (50 NOK) depict mostly playing in the snow and winter weather (focused mainly on children and typical Norwegian winter pastimes), where the larger coins (100 NOK) depict actual Olympic-style competitive sports. That's a Norwegian thing: focus on the next generation. Even the national day, 17th of May, is seen as a children's party (with lots of ice cream and hot dogs).
At the end, the whole set was also released in a wooden case: one type with and one without the gold coins. As you can see: my set has the holes for the gold coins, but lacks the coins. I'm working on it. Those gold coins actually go for about bullion value, so they might be a good investment opportunity.
You may also notice that king Olav died after the first two coin pairs were struck (but before they were released) and that his son, Harald, took over as king. In good tradition, he faces the opposite direction of his father (just like Haakon will do again when he'll be king).
A final thing: you may actually see some blurry details of me holding the camera. Sorry to ruin your day

but those coins are just so shiny...
