Can someone help me identify this and maybe give an estimate for it i dont plan on getting rid of it i just want to know out of pure curiosity. Its my grandads old pendant, ive been wearing it for years and decided to do some research. I can find alll hallmarks on the bar except the PA&S in images online. Any help is appreciated.
The hallmarks are certainly unambiguous: sterling, assayed in London, 1977. The PA&S maker’s mark eludes me, however. The assay office might be able to shed some light on it.
