拍品描述： SWEDEN: Frederick I, 1720-1751, AE 4 daler, Avesta, 1727, KM-PM74, Ahlström-190, 250x237mm, "plate money" (plåtmynt), corner stamps have crowned FRS lettering with date below which translates as (FRS = FRIDERICUS I REX SVECIAE) Frederick I King of Sweden, a lovely weight-adjusted example with very bold stamps and attractive chocolate patina! EF. 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, up to several kilograms. 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.
