Half gold sovereign value comes down to two figures: the gold inside the coin, and the premium charged above it. A half sovereign contains 3.66119 g of fine gold, which is 0.117710 of a troy ounce. With gold at £3,390.98 per troy ounce as at 21 August 2026, that gold content is worth about £399.29, against about £798.58 for a full sovereign.
That gold content figure is the reference point every quoted price is built from. The difference between it and the price on any quote is the premium: minting, distribution, dealing and, on graded coins, certification. This page sets out the arithmetic in both directions, so you can work out what the gold is worth and what a given seller is charging above it.
Gold is not a regulated investment in the UK, and its price falls as well as rises. The figures here are a snapshot at a stated moment rather than a forecast, and the regulatory position is set out in full further down the page.
The gold in a half sovereign
The half sovereign is a 22 carat coin: eleven parts gold to one part copper alloy, a fineness of 0.916667. The remaining 8.33 per cent copper is there for hardness rather than for value. Only the gold counts in a valuation.
| Specification | Half sovereign | Full sovereign |
|---|---|---|
| Gross weight | 3.99403 g | 7.98805 g |
| Fineness | 0.916667 (22 carat) | 0.916667 (22 carat) |
| Fine gold content | 3.66119 g | 7.32238 g |
| Fine gold, troy ounces | 0.117710 oz | 0.235420 oz |
| Face value | 50p | £1 |
These are nominal figures, derived from the standard the coins are struck to. Individual coins vary within mint tolerance, and the Royal Mint publishes its own rounded specifications, including diameter and thickness, which are the figures to check a particular coin against.
The face value is a legal formality and has nothing to do with what the coin is worth. It matters for one reason: legal tender status is the basis of the Capital Gains Tax treatment covered below.

How to calculate a half gold sovereign's value
There are two routes to the same answer. Use whichever matches the units your price source quotes.
Route one: by the troy ounce
Multiply the fine gold content in troy ounces by the gold price per troy ounce.
0.117710 × £3,390.98 = £399.29, the gold value of one half sovereign.
Route two: by the gram
Divide the ounce price by 31.1035 to get the price per gram of fine gold, then multiply by the coin's fine gold weight.
(£3,390.98 ÷ 31.1035) × 3.66119 = the same figure.
The mental shortcut
There are 8.4955 half sovereigns to a troy ounce of fine gold. Call it eight and a half. Divide the ounce price by 8.5 and you will be within a fraction of a per cent of the right answer without a calculator. For a full sovereign the figure is 4.2477, so divide by four and a quarter, which gives about £798.58 at the price above.
Gold trades continuously, so any figure calculated from a spot price is a snapshot. The figures on this page are built from the gold price as at 21 August 2026 and refresh in your browser as the market moves, so what you see is current to the last refresh rather than fixed. For how a sovereign's selling price is built up from spot, see our guide to the gold sovereign price.
Run the sum backwards to find the premium
This is the calculation most buyers never do, and it is the one that shows what a price actually contains.
Take the price you have been quoted and divide it by the coin's fine gold content in troy ounces, or multiply it by the factor in the table below, which comes to the same thing. The result is the price per ounce of gold you are being asked to pay. Compare that to the live spot price and the difference is the premium.
| Coin | Fine gold (troy oz) | Multiply the quoted price by |
|---|---|---|
| Half sovereign | 0.117710 | 8.4955 |
| Full sovereign | 0.235420 | 4.2477 |
Run it on both formats from the same dealer on the same day and the comparison stops being a matter of opinion, because both quotes end up in the same unit.
Percentage premiums quoted on coin size alone can mislead, because they are usually expressed against melt value rather than against each other. Implied price per ounce is the common denominator that lets you compare a half against a full, a Britannia, or a bar.
Two half sovereigns hold the same gold as one full sovereign
Two half sovereigns contain 7.32238 g of fine gold. A full sovereign contains 7.32238 g of fine gold. The half was struck as a precise fraction of the sovereign rather than as an approximation, so on the nominal specification the two are the same.
If two halves cost more than one full sovereign, and they generally do, the whole of that difference is premium rather than gold. The reason is structural. Most of the cost of putting a coin in front of a buyer is charged per coin rather than per gram: striking, packaging, shipping, insuring in transit, verifying on the way back in and, where the coin is certified, submitting it for grading. A half sovereign carries roughly the same fixed cost as a full one, with half the gold to spread it across.
Where the half sovereign format earns its premium
- Buying in stages. Halves let each purchase match the amount available rather than waiting to accumulate enough for a full coin.
- Releasing part of a holding. Selling happens coin by coin. Halves allow a smaller step, so raising a specific sum need not mean converting more than intended. With fulls, the smallest step is twice as large.
- Splitting a holding between people. Gifts, or a holding intended to be divided between several people, split into twice as many units. Half sovereigns have long been used this way in the UK.
- A lower outlay per coin. The smallest unit is half the size, so each individual purchase can be smaller.
Where the full sovereign costs less per gram
- Lower premium per gram on the way in. The same fixed costs sit against twice as much metal.
- The same effect on the way out. Buy-back is also priced per coin, so the spread as a proportion of value tends to be wider on the smaller format.
- Certification is charged per coin. On independently graded coins, the grading fee sits against half as much gold on a half sovereign as it does on a full one.
- Twice as many coins for the same gold. More items to store, insure, count, verify and ship, which counts against the smaller coin wherever storage or admin is charged per item rather than by value.
The question that separates the two formats is whether you expect to use the divisibility. Neither format changes the underlying risk: gold is unregulated in the UK, the price falls as well as rises, and both coins track it in the same direction.
If you are also weighing the sovereign against the one ounce coin, our comparison of the gold sovereign and the Britannia covers the same trade-off at the other end of the size range.
What moves a half sovereign's value beyond its gold
Wear, and the weight that goes with it
A half sovereign that spent decades in circulation has lost gold to abrasion, and a genuine Victorian or Edwardian coin can weigh noticeably under the nominal 3.99403 g while being entirely authentic. Value follows actual gold content rather than the nominal specification, so a worn coin is worth less than a full-weight one, and a dealer pricing it as bullion will weigh it rather than assume.
To put a figure on it, divide the coin's measured gross weight by 3.99403 and apply that proportion to the gold value above. A coin reading 3.90 g holds roughly 97.6 per cent of the nominal gold, so its metal is worth roughly 97.6 per cent of £399.29.
Weight well below the nominal figure is worth a second look for other reasons too. It can be ordinary wear, but it can also point to mounting for jewellery, filing, damage or a counterfeit. Weight, diameter and thickness together, checked against the Royal Mint's published specification for the denomination, are the first checks anyone should make, and anything doubtful should be assessed by someone qualified to do it.
Date, monarch and mint mark
Most half sovereigns trade close to their gold value. A minority do not. Earlier issues, coins struck at the branch mints, and coins in exceptional condition can carry a numismatic premium that has nothing to do with the gold price.
Half sovereigns were struck at branch mints as well as in London, and each branch mint coin carries a mark: S for Sydney, M for Melbourne and P for Perth in Australia, and SA for Pretoria in South Africa. A coin with no mark was struck in London. The mark sits on the reverse, in the exergue beneath the design on St George coins and below the shield on shield reverse coins.
Design and monarch matter as well. Victorian half sovereigns run through young head, jubilee head and old head portraits, with both shield and St George reverses, and the earliest Sydney Mint coins carry a distinct local design rather than either. Edward VII, George V and later issues form their own series again.
None of that puts a value on a particular coin, and this page does not attempt to. What it does mean is that a group of inherited half sovereigns is worth identifying by date, monarch and mint mark, against a current specialist catalogue or with a dealer who prices numismatically, before any of them are sold at a bullion price.
Condition and independent grading
Where condition forms part of the value, it needs establishing by someone with no interest in the sale. Coins graded by NGC or PCGS are sealed, assigned a grade on a published scale, and given a serial number that can be verified directly with the grading service. That separates the two components of value, the gold and the grade, and makes each one checkable. Our page on independently graded coins explains how the process works and what the numbers mean.
Proof half sovereigns are a separate category again. They are struck for collectors rather than for circulation, and are priced accordingly.
Tax on half sovereigns in the UK
Two exemptions are commonly relevant, and they work in different ways. Both are set out here as general information rather than as tax advice.
Capital Gains Tax. As the rules stand at 21 August 2026, UK legal tender gold coins, which includes the sovereign and the half sovereign, are exempt from Capital Gains Tax. The exemption follows from legal tender status rather than from the gold, which is why that nominal 50p face value matters after all.
VAT. As the rules stand at 21 August 2026, gold coins meeting the HMRC investment gold definition are exempt from VAT. Purity is only the first test. The definition requires a coin of a purity of at least 900 thousandths, equivalent to 21.6 carat, and at 916.667 thousandths, or 22 carat, a half sovereign is above that minimum.
Purity on its own is not sufficient. To fall inside the definition, a coin must also have been minted after 1800, be or have been legal tender in its country of origin, and normally be sold at a price not exceeding 180 per cent of the open market value of the gold it contains. HMRC also publishes a list of coins it treats as investment gold. Ordinary bullion half sovereigns sit well inside the 180 per cent ceiling. Heavily collectable pieces sold at large multiples of their gold value are a different matter, and if you are paying a substantial numismatic premium it is worth confirming how the coin is being treated rather than assuming.
Tax treatment depends on your individual circumstances and can change. Nothing here is tax advice. Our guide to Capital Gains Tax on gold in the UK goes into the detail, and anything specific to your circumstances should go to a qualified adviser.
Half sovereign price today, and what a scrap buyer pays
Three different numbers get called the price of a half sovereign, and they are rarely the same. The gold value is about £399.29 at £3,390.98 per ounce as at 21 August 2026. The buying price is that figure plus a premium. The selling price is what a buyer will pay you, which sits below the gold value by their margin unless the coin carries value beyond its metal.
Scrap value is the lowest of the three. A scrap buyer prices against the metal rather than the coin, usually per gram and at a rate set to leave a refining and dealing margin, and takes no account of date, mint mark or condition. Coin buyers price against the coin. The gap between the two can be wide on anything other than a worn, common date example.
Whatever you are offered, divide it by 0.117710 to see the implied price per ounce you are being paid, then compare that to the live spot price. That single number tells you more than any percentage quoted at you.
Three things to establish before accepting an offer.
- Whether the coin is worth more than its gold. Check date, monarch and mint mark first. Selling a scarce date at a bullion price cannot be undone.
- Whether you are being paid as coin or as scrap. These are different prices, and the basis should be stated before the coins leave your hands.
- What the settlement terms are. When the coins are verified, when payment is released, and who carries the risk in transit.
Bullion Club offers buy-back at prevailing market rates on coins bought from us, with settlement once the coins have been received and verified. We do not buy coins that were bought elsewhere. Our guide to selling gold sovereigns covers the process in full.
Risk and regulation
Gold investment is not regulated in the UK. There is no FCA protection, no cover from the Financial Services Compensation Scheme, and no recourse to the Financial Ombudsman Service.
The gold price falls as well as rises, sometimes substantially and for extended periods, and the value of a half sovereign moves with it. Past movements in the price are not a guide to future ones, and nobody can tell you where it goes next.
What can be established is narrower: what the coin contains, what that content is worth at a stated moment, and what you are being charged above it. Those are the three things this page has tried to make checkable.
A one-minute check before you buy
- Note the live gold price per troy ounce. As at 21 August 2026 it is £3,390.98.
- Multiply the quoted price of the half sovereign by 8.4955. That is the implied price per ounce you are paying.
- Compare it to spot. The difference is the premium, in a unit that compares across coin sizes.
- Run the same test on a full sovereign, multiplying by 4.2477, and see what the smaller format costs by comparison.
- Decide whether the divisibility is worth that difference in your own circumstances, bearing in mind that the price of both coins falls as well as rises.
The method takes a minute and works on any dealer's quote.
Where to go next
Bullion Club supplies independently graded Royal Mint gold coins to UK investors. Each coin is graded by NGC or PCGS and carries a serial number you can verify with the grading service, and coins can be delivered under insurance or held in segregated vault storage. The coins currently listed are on our gold sovereigns page.

Frequently asked questions
How much is a half gold sovereign worth today?
Its gold content is 0.117710 troy ounces, so the metal is worth 0.117710 multiplied by the live gold price. At £3,390.98 per troy ounce as at 21 August 2026, that is about £399.29. What you pay to buy one, or receive when selling one, will differ from that by the dealer's premium or spread. Scarce dates and high-grade examples can be worth more than their gold. The price moves continuously and falls as well as rises.
How many half sovereigns make a troy ounce of gold?
8.4955 half sovereigns contain one troy ounce of fine gold, so roughly eight and a half. For a quick estimate of the gold value, divide the gold price per ounce by 8.5. The equivalent figure for full sovereigns is 4.2477, about four and a quarter to the ounce. Those two multipliers are the fastest way to compare prices across the two coin sizes.
Is a half sovereign worth exactly half a full sovereign?
Its nominal gold content is exactly half: 3.66119 g against 7.32238 g. Its price is not. Two half sovereigns almost always cost more than one full sovereign, and the whole of the difference is premium rather than gold. Striking, shipping, insuring and verifying a coin cost much the same per coin whatever its size, so the smaller coin carries those fixed costs against half the metal.
How much gold is in a half sovereign?
3.66119 g of fine gold. The coin weighs 3.99403 g in total on the nominal specification and is 22 carat, a fineness of 0.916667, with the remaining 8.33 per cent copper alloy added for hardness. In troy ounces the fine gold content is 0.117710 oz. The copper adds nothing meaningful to value, so valuation arithmetic should use the fine gold figure rather than the gross weight.
Are half sovereigns exempt from Capital Gains Tax?
Half sovereigns are UK legal tender, and as the rules stand at 21 August 2026, UK legal tender gold coins are exempt from Capital Gains Tax. The exemption follows from legal tender status rather than from gold content, which is why the nominal 50p face value matters. This is general information rather than tax advice. Tax treatment depends on your individual circumstances and can change, so confirm your own position with a qualified adviser.
Do I pay VAT on a half sovereign?
Gold coins meeting the HMRC investment gold definition are exempt from VAT as the rules stand at 21 August 2026. The definition sets a minimum purity of 900 thousandths, or 21.6 carat, which a half sovereign exceeds at 916.667. It also requires the coin to be minted after 1800, to be or have been legal tender, and normally to sell at no more than 180 per cent of its gold value. This is general information rather than tax advice, so check your own position with a qualified adviser.
My half sovereign weighs less than the nominal 3.99403 g. Is it a fake?
Not necessarily. Circulated half sovereigns lose gold to abrasion, and a genuine Victorian or Edwardian coin can read noticeably under the nominal weight after decades of handling. Because value follows actual gold content, divide the measured gross weight by 3.99403 to see what proportion of the nominal gold remains. Significant underweight can also indicate mounting, filing, damage or a counterfeit, so check diameter and thickness too, and have anything doubtful assessed.
Are older half sovereigns worth more than modern ones?
Most half sovereigns of any age trade close to their gold value. A minority do not: earlier issues, branch mint coins, and coins in exceptional condition can carry a numismatic premium unrelated to the gold price. Branch mint marks are S for Sydney, M for Melbourne, P for Perth and SA for Pretoria, shown on the reverse, in the exergue beneath the design on St George coins and below the shield on shield reverse coins. Identify dates and marks before selling anything as bullion.
What is the difference between buying half sovereigns and full sovereigns?
The gold content differs by a factor of two, and the premium differs per gram. Halves allow smaller purchases and let part of a holding be released without converting more than intended. Fulls carry the same fixed per coin costs against twice as much gold, so they cost less per gram both when buying and when selling. Gold is unregulated in the UK and the price falls as well as rises, whichever format is held.
