Hello, hoping someone may be able to identify this mark I found on the back of a silver brooch.
Could it be an XRF silver test result? Any ideas to its meaning? Many thanks if you can help.
Probably an owner’s inventory mark - or possibly a pawnbroker’s mark. I wouldn’t know about an XRF test but I would expect it to be a series of percentages for the constituent metal ratios.
Thanks for your prompt reply. As I’m selling the brooch I wanted to explain the mark to the buyer.
