AND OBJECTS OF VERTU

EUROPEAN COUNTRIES SILVER AND GOLD HALLMARKS
DENMARK MAKER'S MARKS: O
A silver or gold object that is to be sold commercially is, in most countries, stamped with one or more hallmarks indicating the purity of the metal and the mark of the manufacturer or silversmith
The word "HALLMARK" derives from the fact that, since the 16th century, precious metals were sent to the London Goldsmiths' Hall for testing to ensure that the correct standard of silver had been used. The Goldsmiths' Hall was the headquarters of the Goldsmiths' Company and the home of the Assay Office.
In some countries, the testing of precious metal objects and marking of purity is controlled by a national assay office.
Depending on the national legislation the use of hallmarks may be compulsory, voluntary or provided by a manufacturer's declaration.
The Danish hallmarking system is organized on a voluntary base.
The first Danish hallmarking was made in Copenhagen at the end of the 15th century.
Later, other cities as Aalbotg, Aarhus, Odense and Viborg introduced their own mark as a guarantee of precious metals.
In 1893 the "Three-tower" mark of Copenhagen was adopted as the national mark in the new standardized hallmarking system. Copenhagen had the only Assay Office in Denmark.
