Why this is such an interesting find:
The years 1160 - 1180 are two decades when the Swedish kingdom was fought over by the Sverkerska and Erikska families. During the latter half of the 12th century and until 1248 members of those families intermittently held the title of Swedish King.
The Sverkerska family had its main hold in Östergötland (to the east of Visingsö) and was often allied with the Catholic Church. The Erikska family heralded from Västergötland (to the west of Visingsö) and had its power base mainly among the lords and chieftains of the area that made up Sweden at that time.
Unfortunately, not many written records from this era have remained, and therefore these coins may be very useful for the historians.
Thank you for the information. That’s really interesting.
Thanks SB!
