3 Polker - Carl XI Riga

Carl XI was only thirteen when he nominally assumed the Swedish throne in 1660, with the realm governed by a regency council through most of the following decade. Coinage struck in his name from Riga during this period reflects that transitional administration rather than any royal directive. The Riga mint operated under the oversight of Swedish provincial authorities in Livonia, a territory seized from Poland-Lithuania during the 1620s and formally ceded by the Treaty of Oliva in 1660 — making 1669 a relatively early date in consolidated Swedish control of the region.

The polker denomination, a Swedish-Livonian adaptation of the Polish półtorak, persisted in local circulation well after equivalent issues had ceased elsewhere in the Swedish empire.
