1 Öre - Sigismund

Reval — modern Tallinn — occupied a precarious position in 1597, nominally under the Swedish crown following the Livonian War but resistant to direct royal interference in its municipal privileges. Sigismund III Vasa, simultaneously King of Sweden and Poland, was already in open conflict with his uncle Duke Charles over control of Sweden itself. The city's continued right to strike its own coinage was one of several autonomy claims it defended aggressively during this period of dynastic instability.

Sigismund was formally deposed by the Swedish Riksdag in 1599, making this a short-lived regal type by any measure.
