This Swedish plate money is made of copper metal and weighs 31 pounds. When it was made in 1663, Sweden had a lot of copper in its mines, but very little silver metal. This made silver much more valuable than copper.
The design at the center of the plate shows it was worth about 8 Swedish dollars, called dalers. In 1663 this plate could buy four pigs.
Sweden’s biggest copper mine is called the Falun (FA-loon) mine. People mined copper there for over 1,000 years (until 1992). It produced more copper than any other mine in Europe.
