Håkon Magnusson issued this penning before his formal accession as king in 1299, during his tenure as Duke of Norway — a title his father Magnus Lagabøte had created specifically for him in 1273. The third minting period designation reflects Skaare's die-study classification rather than any documented administrative change, and examples attributable to this grouping are scarce enough that individual die linkages remain a live area of research.
