This outstanding type was struck to commemorate the celebration of king Frederik as a sovereign monarch of Norway. The ceremony took place at Akershus on August 15th 1661 in the presence of crown prince Christian V. While the obverse had previously been used for the regular Speciedalers from 1659 and 1660 (Aagaard die 59-4), the reverse is in every way unique in Scandinavian monetary history. Below the text "Aggers Haus" is a beautifully composed and balanced rendering of Akershus Castle on top of a rock overlooking the sea. Akershus, which can still be visited in the Norwegian capital Oslo, was constructed around 1300 to protect and provide a royal residence for the city. Many late medieval monarchs resided there, including Margaret (Margrethe) I (1375-1412), who was the architect of the Kalmar Treaty which united the Scandinavian countries Denmark, Norway (with Iceland) and Sweden (with Finland) under a Danish monarch. Christian IV, always very personally involved in the architectural design of official buildings, first transformed Akershus from a medieval castle into a regular fortress in 1592 and then from 1637 onwards into a full-blown renaissance castle complete with Italian inspired bastions, also visible on the design of the coin. A Portugaloser (Schou-2) struck from the same reverse die but with a different obverse die cut a year earlier (Aagaard 60-1) is known in three examples: one in the Royal Coin Cabinet at the National Museum of Denmark, one in the Coin Cabinet (Universitetets Myntkabinett) in Oslo and Bruun-10080 from the C. F. Schubart collection.
