Chain necklace 800 silver?

This tests very positively for silver although it was tagged plated in the charity shop.
It’s stamped 80 on each side of the clasp and I was wondering if it could be a bad 800 stamp rather than an 80?
What do you think please?
Thankyou

 

Wouldn't surprise me if it were a badly struck 800. That happens early and often.

 

Thankyou. I couldn’t find any mention of 80 on the web so that would seem to be the logical answer.

 

In certain parts of Europe plated items are often marked with a 2 digit number representing the amount of silver used in the plating. I've never seen one that high that it would be 80. A mis-stamped 800 is much more likely.

 

That’s interesting! I didn’t know that. Are there set numbers as in fineness hallmarks or is it a bit random?

 

Is this what you mean @Bakersgma ?

I'm not sure of your question, but here are 2 articles from the Library in the 925 site.

Yes that is the second article I intended to attach. Took me too long to get there.

 

90 is a common silverplate mark. I've also seen 1000.

 

I have had silver plated flatware give a strong silver result using the 18k acid test, so be cautious.

The following test can be used, but beware, it can damage the piece if it is not silver. Give it a good, strong rub in an inconspicuous place, to get through any possible plating, then dip that spot in 14k acid. If it turns a grayish color that can be polished back to silver, it is silver. If it has tiny green bubbles or leaves a spot that can't be polished back, not silver.

I don't recall getting a good 18K test and a failed 14k test with any jewelry, just flatware. That said, I have a couple of pieces of jewelry that pass both tests, but I just don't believe are silver. Next time I go scrap, I'll have them test them on their machine.

 

It’s not magnetic

 

80/90/100 are silverplate standards in the German system used for flatware.
80 with and without a small additional O were also used in Italy for 800 silver.
