Unknown silver mark

Can somebody help with this mark? Is it silver plated or solid silver?

 

Welcome, matyi77. I'm afraid your picture of the mark too small, and perhaps too far away, to see what is there in enough detail. Please try again and when you upload select "Full Image" instead of "Thumbnail."

 

All I see is some squiggles.

 

You may very well be right, Davey. But what is there doesn't look like any silver marks for those countries that I know of.

 

To me too, although some of the letters may be being used as numbers. For instance, the one that looks like a little O could be a 5.

 

Always post a pic of the item,you never know what might spark a thought.
