1/2 Speciedaler - Frederik III

Frederik III issued this coin during the Great Northern War's Danish phase, when Norway was under sustained military pressure from Sweden following the catastrophic loss of the Scanian provinces. The 1659–1660 window is particularly significant: it brackets the Treaty of Roskilde (February 1658) and the subsequent siege of Copenhagen, a period when the Danish-Norwegian crown desperately needed to finance continued resistance and pay garrisons.

Rønning 51 and Skaare 546 represent a tightly documented type with limited die variation, though surviving examples from this two-year window are scarce enough that major collections rarely hold more than one.
