Gold Bars vs Gold Coins: Pros and Cons for UK Investors

Once you have decided to buy physical gold, the next question is gold coins vs bars. Bars look like the serious option: simple, heavy and cheap per ounce. Coins feel more familiar and easier to sell. Which one gives you more gold for your money in the UK? The answer depends on size, tax, how you might sell, and how you store your gold.

In this guide we compare gold bars and gold coins using real GBP prices from UK dealers tracked by Metals Radar. You will see premiums over spot by size, buy-back spreads, VAT and Capital Gains Tax rules, a worked tax example, and a simple decision guide. An FAQ closes the article.

Gold Coins vs Bars: The Short Answer

Here is the quick version for UK buyers:

• Want tax-free gains? Choose Sovereigns or gold Britannias. They are exempt from Capital Gains Tax.
• Investing a large sum for the long term? Larger bars (100 g to 1 kg) usually have the lowest premiums.
• Buying 1 oz at a time? Popular coins such as the Krugerrand or Maple Leaf can cost less over spot than a 1 oz bar.
• Want to sell in small parts? Coins and small bars are easier to sell one at a time.
• Holding gold in a pension? Only bars qualify for a SIPP under HMRC’s rules.

So is a gold bar always cheaper than a coin? No, at the 1 oz size the cheapest coins beat the cheapest bars in our data.

What’s the Difference Between Gold Bars and Gold Coins?

Both are bullion: gold bought for its metal content rather than as jewellery or a collector’s rarity. The price of both starts from the spot price, the live wholesale price of one troy ounce of pure gold. You can follow it on our gold price chart in pounds.

HMRC’s own VAT guidance sums up the purpose of both in one sentence:

“For investment purposes, gold is minted or transformed into coins, ingots, bars and wafers as a store of value and a hedge against inflation.”

What is a gold bar?

A gold bar is a block of refined gold made by a refinery or a mint. Bars range from 1 gram to the 400 oz bars traded between banks. For UK VAT purposes, investment bars must be at least 995 parts per 1,000 fine and of a weight accepted by the bullion markets.

Minted bars

Minted bars are cut from rolled gold and struck with a design. Most bars from 1 g to 100 g are minted and sealed in a tamper-evident card with a serial number and the maker’s guarantee of weight and purity.

Cast bars

Cast bars are made by pouring molten gold into a mould. They look rougher, cost less to make and are common in larger sizes such as 1 kg.

What is a gold bullion coin?

A gold bullion coin is struck by a government mint and usually carries a face value. The face value is symbolic: the coin is worth its gold content. UK examples from The Royal Mint:

• Britannia 1 oz: 999.9 fine gold, one troy ounce, £100 face value.
• Sovereign: 22 carat (916.7), contains 0.2354 troy ounces of gold, £1 face value.

Foreign coins sold widely in the UK include the South African Krugerrand (22 carat, 1 oz of gold), the Canadian Maple Leaf (999.9) and the Austrian Philharmonic (999.9). A 22 carat coin is alloyed with a little copper for durability, but a 1 oz Krugerrand still contains a full troy ounce of gold.

Gold Bars: Pros and Cons

Pros of gold bars

• Lowest premium at larger sizes: a 1 kg bar cost 1.8% over spot on 3 October 2026.
• Efficient for large sums: more of your money buys metal rather than minting costs.
• Compact: a lot of value in a small, stackable form with a serial number.
• VAT-free: qualifying bars carry no VAT in the UK.
• Pension-eligible: investment-grade bars can be held in a SIPP where the provider offers it.

Cons of gold bars

• Capital Gains Tax applies: bars are chargeable assets, so gains above your annual allowance are taxed.
• Hard to sell in parts: you cannot sell half of a 1 kg bar.
• Small bars are expensive: 1 g to 5 g bars cost far more per ounce than a 1 oz coin.
• Wider buy-back spread at 1 oz: in our data a 1 oz bar lost more on a same-day round trip than a 1 oz Krugerrand.

Gold Coins: Pros and Cons

Pros of gold coins

• UK coins are CGT-free: Britannias and Sovereigns from 1837 are exempt, with no limit on the gain.
• Easy to sell in parts: sell one coin and keep the rest.
• Widely recognised: dealers know the main bullion coins and buy them back readily.
• Low premiums on popular 1 oz coins: the Krugerrand and Maple Leaf were the cheapest 1 oz products in our data.
• Good for gradual buying: Sovereigns and fractional coins let you build a holding over time.

Cons of gold coins

• Small coins cost more per ounce: a 1/10 oz Britannia cost 10.3% over spot.
• More items to store and track: a holding in coins means more pieces to secure.
• Foreign coins are not CGT-free: Krugerrands, Maple Leafs and Philharmonics are chargeable assets in the UK.
• Not allowed in a SIPP: HMRC’s pension exception covers bars and wafers, not coins.

Gold Bars vs Gold Coins at a Glance

Premiums: The Number That Decides Your Real Cost

The premium is the amount you pay above the spot value of the gold. It covers refining or minting, distribution and the dealer’s margin. The formula is simple:

Premium % = (price − spot value of the gold) / spot value × 100

How much did gold bars and coins really cost on 3 October 2026? Here are the lowest listed prices at UK dealers in our data, with spot at £3,135.89 per troy ounce:

Three patterns stand out:

• the bigger the single piece, the lower the premium, because making costs are spread over more gold,
• at 1 oz, the cheapest coins beat the cheapest bars: 1.2% for a Krugerrand against 3.6% for a bar,
• bars under 10 g are an expensive way to buy gold; a Sovereign or a 1/10 oz coin costs less over spot than a 5 g bar.

Delivery matters too. A £5 charge adds about 4% to the cost of a 1 g bar but almost nothing to a 1 oz coin. Compare live prices for 1 kg gold bars, 100 g gold bars, 1 oz gold bars and Krugerrands.

Tax: VAT and Capital Gains Tax on Gold in the UK

Tax is the main reason the coin-or-bar choice matters more in the UK than in many other countries. There are two taxes to understand: VAT when you buy and Capital Gains Tax when you sell.

VAT: investment gold is exempt

Investment gold is a VAT category defined by HMRC. Under VAT Notice 701/21 it covers:

• gold bars and wafers of at least 995 fineness, in weights accepted by the bullion markets,
• gold coins minted after 1800, of at least 900 fineness, that are or have been legal tender in their country of origin and normally sell for no more than 180% of the value of their gold.

Both qualifying bars and qualifying coins are therefore bought free of VAT. Silver and platinum are different: The Royal Mint states that physical silver and platinum bullion are subject to VAT at 20%. That alone makes gold cheaper to hold than investment silver for many UK buyers.

Capital Gains Tax: only UK legal-tender coins are exempt

This is the decisive difference. HMRC’s Capital Gains Manual (CG78305) says that “Sovereigns minted in 1837 and later years and Britannia gold coins are currency but, like all sterling currency, are exempt”. It adds that coins which are currency but not sterling, “for example Krugerrands, are chargeable assets”. Gold bars are chargeable too.

For chargeable assets, the annual exempt amount is £3,000 per person. Gains above it are taxed at 18% within the basic-rate band and 24% above it, according to GOV.UK. These rates have applied since 30 October 2024, when they rose from 10% and 20%.

Worked example: the tax gap

Suppose you invest £30,000 in gold and later sell it for £45,000, a gain of £15,000, with no other gains that year.

In this example, bars could cost up to £2,880 more in tax. On £30,000, a premium gap of one or two percentage points is £300 to £600. If your gains will stay inside the £3,000 allowance, or you can spread sales across tax years, the lower premium of a large bar can still come out ahead.

Three more tax points

1. Inheritance Tax: CGT-free coins are still part of your estate at market value.
2. Pensions: HMRC’s Pensions Tax Manual allows investment-grade gold, defined as a bar or wafer of at least 995 fineness, in an investment-regulated scheme such as a SIPP. Coins are outside this definition.
3. Consumer protection: The Royal Mint notes that bullion products are not regulated by the Financial Conduct Authority, so the Financial Services Compensation Scheme does not cover a dealer failure. Dealer choice matters.

Liquidity: How Easily Can You Sell?

Buying gold is easy. The test is selling at a fair price. Here is the gap between what two UK dealers charged and what they paid back for the same items on the same day:

What does this show? Popular 1 oz coins and the 1 kg bar had the narrowest spreads. A 1 oz bar lost more on a round trip than a 1 oz Krugerrand at these dealers. Sovereigns cost more to trade, in return for being small and CGT-free.

Coins also win on divisibility. You can sell a single Sovereign or 1 oz coin to raise exactly the cash you need. A large bar forces an all-or-nothing sale. Want to know what dealers pay today? See our sell gold page.

Storage and Checking Your Gold Is Genuine

Physical gold has to live somewhere, and the form you choose affects how you store it:

• home storage costs nothing extra but puts all the risk in one place, and home insurance often limits cover for bullion,
• a professional vault charges a yearly fee but offers insured, segregated storage, useful for large bars,
• a coin holding is easy to split across locations; a 1 kg bar is not.

On authenticity, minted bars usually come sealed with a serial number. Coins have set weights, sizes and designs, and newer Royal Mint coins carry security features. Learn the checks for the most common coins in our guides to spotting a fake gold Britannia and a fake Krugerrand.

Which Should You Buy? A Simple Decision Guide

There is no universal winner, only the better choice for your situation. Start from your main priority:

Choose gold bars if:

• you are investing a large sum and want the lowest cost per ounce,
• you want to hold gold in a SIPP,
• your gains are likely to stay within the annual CGT allowance, or you plan to hold for a very long time.

Choose gold coins if:

• you want tax-free gains with Sovereigns or Britannias,
• you buy 1 oz at a time or build your position gradually,
• you may need to sell part of your gold in the future.

Can you mix gold bars and coins?

Yes, and many investors do. A common approach is a few larger bars as a low-cost core and a set of Sovereigns or Britannias for tax-free flexibility. The right mix depends on your budget, tax position and how likely you are to need part of the money. For a wider view, see why buy gold at all.

Common Mistakes When Choosing Between Gold Bars and Coins

1. Buying 1 g and 2 g bars as an investment: at premiums of 23.7% to 35.7%, gold has to rise a lot before you break even.
2. Assuming bars are always cheaper: at 1 oz, popular coins cost less over spot in our data.
3. Forgetting CGT on bars and foreign coins: with a £3,000 allowance, a large gain can mean a large tax bill.
4. Paying collector prices for bullion: proof and limited-edition coins carry premiums that have little to do with gold content.
5. Putting everything into one large bar: you lose the option to sell part of it.
6. Ignoring the dealer: the same 1 oz Krugerrand cost 1.2% over spot at one dealer and 3.8% at another on the same day.
