1 Speciedaler - Frederik III

Frederik III issued these specidalers during the years immediately following the 1660 constitutional revolution that abolished the Danish-Norwegian nobility's tax privileges and transformed the monarchy into an hereditary absolute autocracy. The coins were part of a broader effort to assert royal financial authority through standardized silver coinage at a moment when the crown was simultaneously reorganizing the entire administrative apparatus of the realm.

The Kongsberg silver mine, opened in 1623, supplied the raw material. Production volumes from this short window were modest, and the three-year span across the Rønning 45k type reflects incremental die changes rather than any single concentrated striking campaign.
