What “hallmarking” means
Wiktionary · Wikipediahallmarking
- verbTo provide or stamp with a hallmark.
- nounThe action of making a hallmark
A hallmark is an official mark or series of marks struck on items made of metal, mostly to certify the content of noble metals—such as platinum, gold, silver and in some nations, palladium. In a more general sense, the term hallmark is used to refer to any standard of quality. It is not to be confused with responsibility marks, which indicate the maker.
