12 öre, Svartsjö, Gustav I Vasa, 1543
The coin you see in the display case has a square shape, and is a so-called klippe coin. In 1540, Gustav Vasa moved the mint to Svartsjö on Ekerö in Lake Mälaren. The mint remained in Svartsjö until 1550. Between 1542 and 1543, the Dacke Rebellion against Gustav Vasa took place. The population rebelled, among other things, because of the harsh taxation and less local authority.
The fact that some of Gustav Vasa's coins are klippe coins is usually explained by the fact that the mint needed to mint large quantities of coins quickly to pay for the defence against the rebellion. The klippe coins that were minted were 15 öre (4650 copies), 12 öre (2650 copies), 4 öre (440 copies) and 2 öre (878 copies). All the klippe coins were minted at the Svartsjö mint in 1543. The motif on the klippe coins is a crowned G (Gustav Vasa) and the year 1543 on the obverse (front), and three crowns and the denomination on the reverse.
