Wonderful, the Birmingham Jewellery Quarter, KatyK. I had some bespoke cufflinks made for DH by a jeweller there ten years ago. I couldn't get them made anywhere else. As for the meltdown value, as I said earlier, there are two different carats involved, and, gram for gram, the half sovereign might be worth more than the mount. A half sovereign contains just over three and a half grams of 22 carat gold. A good jeweller should take that into account. Early twentieth century half sovereigns last year were making around £105 at our local auction house, depending on condition. Newly minted ones at the moment are selling for around £120 plus. It's possible that incorporating the coin into a ring could affect its value I suppose.
