1 Søsling - Frederik III

Frederik III issued copper søslinge beginning in 1651, partly to address a chronic shortage of small-denomination coinage that had plagued Danish commerce since the Thirty Years' War disrupted normal trade flows through the Baltic. The søsling — worth half a skilling — was the smallest unit in regular circulation, handling transactions that silver simply couldn't reach economically.

KM#176 is known with considerable variation in flan quality across the run, a predictable consequence of working with rolled copper strip of inconsistent thickness at the Copenhagen mint during this period.
