1445  A royal decree, valid throughout the kingdom. required that every item be stamped with a town hallmark and a maker's mark. 
1523  Until this year, Danish regulations were generally valid for Sweden. 
1685  A decree was issued by Christian IV for Copenhagen, which was the model for other towns of the kingdom as well as for larger towns of Norway, introduced basic changes in the system of marking: each object weighing over 5 lots had to be submitted to the master of the mint for assay. The master then marked it with the town emblem, with a mark of the month, and with his own mark. Henceforth there were four marks on an item: 
1.  the town mark 
2.  the assayer's mark 
3.  the mark of the month 
4.  the maker's mark. 
1814  Until this year Danish regulations applied to Norway as well. 
1893  The law of 5 April, 1888, came into force. Items had now to be marked with 
1.  the producer's mark; 
2.  the fineness figure with the letter "S". 
3.  an official mark with date 
The lowest permissible fineness standard was 826/1000
