Sweden, Karl XI SM 121b jfr 2 mark 1670 9.88 g. Stockholm. Interesting piece struck in copper with original dies. There was no officially recorded mintage in copper, and hence it can be assumed that it is someone at the mint trying out equipment, or trying to make a spurious/fake issue. A similar copper strike with original dies of a 1 mark 1649 was sold at Misab auction 7, lot 1093.
