I know what Kai means because we had a "non forum" conversation about silver and silver alloys a time ago.
Kai means that it could be worth trying pricking it with a steel needle at an inconspicuous place. Low grade silver is tougher though and less easy to differentiate from nickel silver, etc.
Maybe Kai can add or correct me if wrong or not complete!
