Question
I was looking to buy some old Norwegian silverware with different markings.
630-s nm------830-s nm-------60-s nm------630-s-230------630-s nm-----9088-s
09-s nk---o9-sn---830-s nm  cpn.

Can you tell me if this is real silver or just plated?

Answer
Hi, Richard. The "830" designation is very common on Norwegian silver. It means 83% silver content. The sterling standard is 92.5% (925). So, you can calculate how much actual silver is involved. I've not seen the other numbers you mentioned so I can't be certain what they represent. It's reasonable to guess that "630" means 63% but I've not seen it before.

The others raise questions.

See these examples: http://www.925-1000.com/Fnorway_marks.html#1 .
