Swedish plate money
Sweden, 1658
Sweden introduced a copper coinage in the 1620s, with coins that were worth their weight in copper. Swedish copper mines produced huge quantities of the metal, much of it issued as these very large coins. Their size made these coins impractical, and in the 1660s Sweden became the first European country to use paper money.
Eight daler copper plate money, weighing around 15kg. Stamps at the corners give the initials of King Karl X Gustav of Sweden.
