The 1996 Half-Sovereign is a modern Proof issue. It is a half Sovereign, not a full Sovereign and not a £5 coin. Do not compare it with a bullion half Sovereign without accounting for the finish and packaging.
Specifications
Royal Mint specifications list 22-carat gold, a weight of 3.99 grams and a diameter of 19.30 millimetres. Raphael Maklouf designed the Elizabeth II obverse and the reverse uses Pistrucci’s St George and the dragon.
Issue figures
Specialist references report 5,730 individually reported sales or units in the cited Royal Mint data and an issue limit of 7,500. Additional coins in sets are a separate category. These figures are issue data, not surviving-population counts.
How much is it worth?
Proof condition, authenticity, surface quality, original packaging, certificate and demand affect value. Specific overdates and die chips need a recognised catalogue reference and clear photographs. A die chip is not automatically a valuable error.
Compare recent completed sales of the same Proof product and condition. Keep bullion, melt calculations, asking prices and dealer offers separate from completed sales.
