Sweden, Kristina SM 58b 2 mark 1648 10.35 g. Stockholm. Minor scratches. RRR. Ex Sten Törngren, Spink auction May 2000, lot 746. Ex Stockholms Auktionsverk auction March 1991, lot 8177. Ex Antikören auction 8, lot 221. SMB 100. We cite (free translation) from Antikören's auction catalogue: "Tw two mark of 1648 exists in two styles: 1) Mint mark on both sides of shield, 2) Mint mark beneath the shield. Both are very scarce, the latter so scarce that it was not present in important collections such as Bruun and Oldenburg - not even in the Swedish Central Bank (Riksbanken) collection! We have only found one sale - a pierced example at Ahlström auction 30, labelled "RRRR"." Later research has shown that the herewith offered date is today recorded in a futher four examples, for a total of 6. Nevertheless a great rarity! 1/1+
