Plate money

The riksdaler was the name of a Swedish coin first minted in 1604. Between 1777 and 1873, it was the currency of Sweden. The daler, like the dollar, was named after the German Thaler. The similarly named Reichsthaler, rijksdaalder, and rigsdaler were used in Germany and Austria-Hungary, the Netherlands, and Denmark-Norway, respectively. Riksdaler is still used as a colloquial term for kronor in Sweden.

The daler was introduced in 1534. It was initially intended for international use and was divided into 4 marks and then a mark is further subdivided into 8 öres and then a öre is further subdivided into 24 pennings. In 1604, the name was changed to riksdaler ("daler of the realm", c.f. Reichsthaler). In 1609, the riksdaler rose to a value of 6 mark when the other Swedish coins were debased but the riksdaler remained constant.

From 1624, daler were issued in copper as well as silver. Because of the low value of copper, large plate money (plåtmynt) was issued. These were rectangular pieces of copper weighing, in some cases, several kilograms. (The largest one is worth 10 daler and weighs almost 20 kilograms (44 lb)). They circulated until 1776. As silver became scarce, the silver daler rose in value relative to the copper daler, with the exchange rate between the two eventually being set at a ratio of 3 to 1. Denominations in copper money were marked K.M. or KMT, with S.M. or SMT denoting silver money.

The cumbersome size and weight of plate money eventually prompted Sweden to become the first country in Europe to issue banknotes. There were introduced issued by in 1661. The notes lost much of their value due to over production but succeeded in alleviating the immediate problem. They were issued until 1667. In 1681, the silver daler was debased, such that 1 riksdaler = 2 silver daler, with a further debasement in 1712 resulting in 1 riksdaler = 3 silver daler.
