1/2 Penning - Sigurd II & Øystein II

Norway's mid-twelfth century coinage was produced under highly unusual circumstances: Sigurd II Munn and Øystein II ruled simultaneously as co-kings during a period of dynastic fragmentation that would eventually spiral into nearly a century of civil war. This issue belongs to that unstable interregnum before the conflict fully ignited.

Brekke's classification places this among the scarcest of the joint-reign types. Few Norwegian mints of the period have been conclusively identified, and attribution of specific dies to Bergen, Hamar, or Nidaros remains contested among Scandinavian numismatists.
