Kopparplatmynt Publique Deposited
also known as Koppar- platmynt. The name given to large flat rectangular and square pieces of copper, with a stamp of value in each corner and one in the centre. They were issued in Sweden during the seventeenth and eigh- teenth centuries, and may perhaps be con- sidered as weights for the purchase of goods, rather than coins, though some au- thorities state that they were accepted at the value of one third of the Riksdaler (q.v.).
As no complete list of them has ever been published in tabular form, the fol- lowing arrangement will be of assistance to the student and collector.
