2 Skilling Dansk - Frederik III Shield type III

Frederik III inherited a kingdom financially gutted by the Torstenson War and the subsequent Treaty of Roskilde negotiations, and his billon skilling issues of the early 1650s reflect a mint system under sustained pressure. The shield type sequence — running through at least three die configurations across a short window — suggests the Copenhagen mint was adjusting working dies more frequently than was typical for the denomination, likely a consequence of high-volume striking on debased flans that accelerated die wear.

The .281 fineness puts this squarely in territory where silver content was almost incidental to face value — a monetary compromise that would deepen through the decade.
