What does the number after "weighted" mean?

I understand the term weighted as it applies to Sterling Silver pieces but I have noticed that often the term is followed by a three digit number. Does anyone know what this number stands for?

I am a brand new member of this site as well as being relatively new to collecting silver other than bullion. I’m happy to have found this forum…

Welcome to the forum.

I don’t know of any specific meaning for such a number. It may be totally unrelated to “weighted”; for example a pattern number perhaps.

I see, thank you.
