Please help identify if possible also if i cant how can i test if its silver
Not marks I have come across before and neither can I find them in any resource available to me. They don’t appear to be silver marks so electroplate seems most likely.
Several tests are possible. First try a magnet. If it is attracted it is defintely not silver. Otherwise inconclusive as not all base metal alloys are magnetic.
You could try acid testing (kits available online) but this requires scratching deeply into the item to get below any potential silver coating.
The most reliable non-invasive method is X-Ray Fluorescence (XRF) testing. You may find a jeweller or auction house who has the equipment and would be willing to do it for you.
I really appreciate all your help
