The coin series will comprise three gold and three silver coins. The first two coins, one gold and one silver, will be issued on 27 November 2003, to commemorate the day in 1905 when King Haakon VII took his oath in the Storting. The next two coins will be issued on 23 September 2004, to commemorate the day in 1905 when Norway and Sweden came to an agreement in Karlstad regarding a peaceful dissolution of the union. The last two coins will be issued on 7 June 2005, the centennial for the Storting resolution which resulted in the dissolution of the union. The coins will be issued in cooperation with Hundreårsmarkeringen - Norge 2005 AS (Norge 2005) (The Centennial Celebration - Norway 2005 Ltd.), which will be in charge of the official programme.

The motif on the obverse (front) of the coin has been designed by former coin engraver Øivind Hansen. The motif on the front of the coin is the same for all of the coins and is a triple portrait of three kings during the period. The motif on the reverse (back) of the gold coins has been designed by sculptor Tomasz B. Ozdowski, while the motif on the reverse of the silver coins has been designed by Danuta Haremska. The motifs on the reverse of the coins depict Norway during a century of change, from an agricultural society to a modern society facing the challenges of a high-tech future.
