6 Dukater - Karl IX Type I

Karl IX's claim to the Swedish throne was legally contested well into his reign — he had ruled as regent since 1599 after deposing his nephew Sigismund III, but only formally crowned himself king in 1604. Large gold multiples like this six-ducat piece functioned less as currency than as diplomatic gifts and demonstrations of royal legitimacy, issued at a moment when Karl was still fighting to have his kingship recognized abroad. Sweden and Poland-Lithuania remained technically at war over the succession.

KM#20 is among the rarest Swedish gold issues of the early Vasa period, with surviving examples almost exclusively in institutional collections.
