3 Ducats - Christian V Christiania type V, pattern, heavy type

Christian V ascended the Danish-Norwegian throne in 1670 and almost immediately set about reasserting royal prerogative through a sweeping absolutist reorganization formalized in the Kongelov of 1665 — the most explicit codification of absolute monarchy in European history. The Christiania mint was reestablished in part to give physical expression to that authority in Norway specifically, distinct from Copenhagen's output.

This pattern's billon composition — anomalous for a three-ducat denomination, which by definition implies gold — suggests it was struck as a presentation or trial piece to test dies rather than serve any intended monetary function. The heavy-type designation reflects the elevated planchet weight relative to the standard Hede#10 series.
