If you’ve decided to invest in physical gold, you’ve already made a smart move. But now comes the question every UK investor faces at the bullion dealer’s counter: should you buy gold bars or gold coins?
It’s a question we get asked dozens of times every week at our London office, and the honest answer is — it depends. Both have advantages, and the right choice depends on your budget, your investment timeline, your tax position, and how you plan to sell in the future.
This guide breaks down the gold bars vs gold coins debate from a UK investor’s perspective. We’ll compare premiums, taxes, liquidity, storage, and resale — and by the end, you’ll know exactly which option (or combination) is right for you.

Gold Bars vs Gold Coins at a Glance
Before we dive into the detail, here’s a quick side-by-side comparison of the two options for UK investors:
| Feature | Gold Bars | Gold Coins |
| Premium over spot | Lower (1-5%) | Higher (4-10%) |
| VAT in the UK | Exempt (investment grade) | Exempt (investment grade) |
| Capital Gains Tax | Applies | CGT-free for UK legal tender coins |
| Liquidity | Sell whole bar only | Sell coin-by-coin |
| Recognition | Requires assay/certification | Globally recognised by sight |
| Best for | Larger lump-sum investing | Tax-efficient long-term holding |
| Storage | Compact and stackable | Slightly bulkier per gram |
| Minimum entry | From ~£80 (1g bar) | From ~£200 (1/10oz coin) |
The headline takeaway: bars win on cost per gram, but coins win on flexibility, tax efficiency, and ease of selling. Read on to understand why — and which is right for you.
What Are Gold Bars? (And Why UK Investors Buy Them)
Gold bars also called gold bullion bars or gold ingots — are simply rectangular blocks of refined gold produced by professional refiners. For investment purposes, they’re typically 99.5% pure or higher (most reputable bars are 999.9 fine, meaning 99.99% pure).
Bars are valued almost entirely on their gold content. There’s no design premium, no minting cost, no historical value — just the weight of the metal. This is why bars carry the lowest premiums over the spot gold price.
Sizes Available (From 1g to 1kg)
Gold bars come in a remarkable range of sizes, suitable for every budget:
- 1g, 5g, 10g, 20g — Entry-level investing or gifts
- 50g, 100g — The most popular size range for UK investors
- 250g, 500g — Mid-range lump-sum investments
- 1kg — The institutional standard, lowest premium per gram
- Larger bars (e.g. 400oz Good Delivery bars) — Used by central banks and major institutions
As a general rule, the bigger the bar, the lower the premium per gram. A 1kg bar might carry a 1-2% premium over spot, while a 5g bar can carry 5-8% — because the refining, stamping, and certification costs are spread across less metal.
LBMA-Approved Refiners (What to Look For)
Not all gold bars are equal. To ensure authenticity and resale value, only buy bars produced by refiners on the LBMA (London Bullion Market Association) Good Delivery List. Trusted names include:
- PAMP Suisse
- Heraeus
- Metalor
- Umicore
- Argor-Heraeus
- Valcambi
- The Royal Mint (UK)
Each bar comes with a serial number, weight, purity stamp, and refiner’s mark. Smaller bars (typically under 100g) are sealed in tamper-evident assay cards — never break this seal, as it preserves authentication and resale value.
Best Gold Bars to Buy in the UK
For UK investors, the most popular and liquid bar sizes are:
- 100g gold bars — The sweet spot of affordability and lower premiums
- 1oz (31.1g) gold bars — Internationally standardised weight, easy to value
- 1kg gold bars — Best premium per gram for larger investments
Avoid unbranded or unknown-refiner bars — they’re cheaper for a reason, and harder to sell.
What Are Gold Coins? (Types and Popular Choices)
Gold coins are produced by official government mints around the world. Unlike bars, they have a face value (legal tender status) and feature intricate designs that make them instantly recognisable globally.
Bullion Coins vs Numismatic Coins
It’s important to understand the difference:
- Bullion coins are valued primarily on their gold content. Modern Britannias, Sovereigns, and Krugerrands are bullion coins. These are what most investors buy.
- Numismatic (collectable) coins carry an additional premium for rarity, age, or historical significance. A 1937 Edward VIII Sovereign, for example, is worth far more than its gold content. These are for collectors, not investors.
For pure investment purposes, stick to modern bullion coins. They’re easier to value, easier to sell, and you won’t overpay for collectability you may not recover.
Best Gold Coins to Buy for Investment in the UK
UK investors have access to dozens of gold coins, but a few stand out as the smartest choices:
Gold Sovereign — Produced by The Royal Mint since 1817, the Sovereign is a 7.98g coin in 22-carat gold. It’s UK legal tender, CGT-free, and one of the most recognised and traded gold coins in the world. Available in full, half, quarter, and double Sovereign sizes.
Gold Britannia — A 1oz (31.1g) coin in 999.9 fine gold, also produced by The Royal Mint. UK legal tender, CGT-free, and available in fractional sizes (1/10oz, 1/4oz, 1/2oz). The 2025 King Charles III edition is one of the most popular coins among UK buyers.
Krugerrand — The original modern bullion coin, produced by the South African Mint since 1967. It’s a 1oz coin in 22-carat gold (with a copper alloy for durability) and is the world’s most widely traded gold coin. Not CGT-exempt for UK investors.
Canadian Maple Leaf — Produced by the Royal Canadian Mint, the Maple Leaf is 1oz of 999.9 fine gold. Famous for its anti-counterfeiting features. Not CGT-exempt for UK investors.
American Eagle — The official US bullion coin, 1oz of 22-carat gold. Popular internationally but not CGT-exempt in the UK.
Buying Gold Sovereigns (The Classic UK Choice)
The Gold Sovereign has been the UK’s standard gold coin for over 200 years. Its smaller size (around £400-500 each at current prices) makes it perfect for building a portfolio gradually, gifting, or selling small portions when needed. Older Sovereigns (pre-1937) often trade at the same premium as modern ones, giving you a piece of history at no extra cost.
Buying Gold Britannias (The Modern UK Investor’s Favourite)
If you want pure 999.9 gold with CGT exemption in a single coin, the Britannia is unbeatable. The full 1oz coin gives you maximum gold content per coin (and therefore lower handling per ounce than buying ten Sovereigns), while still being divisible if you want to sell only part of your holding.
Gold Bars vs Gold Coins: 7 Key Differences
Now let’s get into the detailed comparison. Here are the seven factors UK investors need to weigh up.
1. Premium Over Spot Price (Why Gold Bars Are Cheaper)
The premium is the difference between the dealer’s selling price and the live spot gold price. It covers refining, minting, distribution, and dealer margin.
Gold bars have lower premiums because they’re simpler to produce — no intricate minting, no legal tender status, just refined metal. A 1kg gold bar might carry a 1-2% premium, while a 1oz bar might carry 2-4%.
Gold coins carry higher premiums because mints invest in detailed designs, anti-counterfeiting features, and packaging. A 1oz Britannia typically carries a 4-7% premium, and smaller fractional coins (1/10oz) can carry 8-12% or more.
Winner on cost: Gold bars.
2. Liquidity and Ease of Selling
This is where coins shine. Imagine you’ve invested £30,000 in gold. Five years later, you need £3,000 for a car repair. If you bought a single 500g bar, you’d have to sell the entire bar — even though you only need a fraction of its value. With coins, you simply sell a Sovereign or two.
Coins are also easier to sell privately. They’re instantly recognisable — anyone can verify a Britannia by sight and weight. Bars require an assay card and refiner verification, which slows down the process.
Winner on liquidity: Gold coins.
3. Capital Gains Tax (The UK Investor’s Trump Card)
This is arguably the most important factor for UK investors — and it’s often overlooked.
Gold bars are subject to Capital Gains Tax. If you buy a 100g bar for £6,000 and sell it five years later for £10,000, you have a £4,000 gain. After your £3,000 annual CGT allowance, you’d pay 10% or 20% on the remaining £1,000.
UK gold coins (Sovereigns, Britannias, Queen’s Beasts, Tudor Beasts, and Lunar series) are completely CGT-free because they’re UK legal tender. Make £4,000, £40,000, or £400,000 in gains — you pay zero CGT. Forever.
This single difference can save UK investors thousands of pounds over time. For long-term wealth preservation, CGT-exempt coins are extraordinarily powerful.
Winner on tax efficiency: UK gold coins (Sovereigns and Britannias).
4. Divisibility and Flexibility
As mentioned, coins let you sell in smaller increments. A portfolio of 30 Sovereigns gives you 30 sale points. A single 250g bar gives you one.
This flexibility also helps with inheritance planning. Distributing 30 Sovereigns among three grandchildren is far simpler than dividing a single bar.
Winner on flexibility: Gold coins.
5. Storage Considerations
For the same gold weight, bars are more compact than coins. A 1kg gold bar takes up roughly the space of a credit card. The same kilogram in 1oz Britannias would require 32 coins.
If you’re using a home safe with limited space, bars are more efficient. If you’re using professional vault storage (charged by weight), the difference is minimal.
Winner on storage: Gold bars (marginal).
6. Authentication and Counterfeit Risk
Bars rely on serial numbers, assay cards, and refiner reputation. If the assay seal is broken, resale becomes harder. Sophisticated fakes do exist (drilled tungsten cores in larger bars are a known issue), though LBMA-approved sources virtually eliminate this risk.
Coins have built-in anti-counterfeiting features: precise weight, dimensions, microengraving, magnetic signatures. Britannias, for example, include a latent image and tincture lines that are nearly impossible to fake. Anyone with a basic gold-testing kit can verify a coin in seconds.
Winner on verifiability: Gold coins.
7. Resale Value and Long-Term Performance
Both bars and coins track the gold spot price closely. However, coins often retain a slight premium even in private sales — buyers will pay a small markup for a recognised coin over a generic bar of equivalent gold weight.
In a hypothetical liquidity crunch (where you need to sell quickly), coins consistently sell faster than bars. Most UK dealers actively advertise to buy Sovereigns and Britannias because demand is so steady.
Winner on resale: Gold coins (slight edge).
When Should You Buy Gold Bars?
Gold bars are the right choice when:
- You’re investing a large lump sum (£10,000+) and want maximum gold for your money.
- You have a long holding horizon (10+ years) and plan to sell in one transaction.
- You’re holding within a tax-efficient wrapper (e.g. a SIPP) where CGT doesn’t apply.
- You already have a CGT-exempt coin portfolio and want to add cost-efficient bulk gold.
- You prioritise compact storage.
- You’re an experienced investor comfortable with assay-based authentication.
When Should You Buy Gold Coins?
Gold coins are the right choice when:
- You’re a UK taxpayer wanting to legally avoid Capital Gains Tax (Sovereigns and Britannias).
- You’re building a portfolio gradually with smaller, regular purchases.
- You want flexibility to sell portions of your holding rather than the whole.
- You may want to gift gold to family members.
- You value instant recognition and easy verification.
- You’re new to gold investing and want the safest, most liquid entry point.
- You’re planning for inheritance and want easy distribution among beneficiaries.
Should You Buy Both Gold Bars and Coins?
For most UK investors with portfolios over £20,000, the answer is yes. A balanced approach captures the benefits of both:
- Core holding (60-80%) — CGT-free UK coins (Britannias and Sovereigns) for tax-efficient long-term wealth preservation
- Cost-efficient bulk (20-40%) — LBMA-approved gold bars (100g or 1kg) for lower premiums on the bulk of your investment
This blended approach gives you the lower-cost-per-gram of bars on a portion of your holding, while the CGT-exempt coins handle the bulk of your potential gains. Many of our clients in London follow exactly this structure.
Real Cost Comparison: Gold Bars vs Gold Coins
Let’s look at what £10,000 actually buys you in different formats (using illustrative spot price of £2,400 per oz). These are illustrative figures only — always check live prices before buying.
| Product | Approx Premium | Gold You Get (£10k) | CGT? |
| 1kg Gold Bar | 1-2% | ~127g | Yes |
| 100g Gold Bar | 2-3% | ~125g | Yes |
| 1oz Gold Britannia | 4-6% | ~120g | No (CGT-free) |
| Gold Sovereign | 5-7% | ~118g | No (CGT-free) |
| 1/10oz Britannia | 8-12% | ~112g | No (CGT-free) |
Yes, you get less gram-for-gram with coins. But if that same gold doubles in value over a decade, the CGT savings on Britannias and Sovereigns will likely outweigh the premium difference — especially for higher-rate taxpayers.

Frequently Asked Questions
Is it better to buy gold coins or bars in the UK?
For UK investors, gold coins (specifically Sovereigns and Britannias) are usually better for long-term wealth preservation because they are exempt from Capital Gains Tax. Gold bars are better for larger lump-sum investments where lower premiums matter more, or for holding within a SIPP.
Are gold coins or bars a better investment?
Both track the gold price equally, so neither outperforms the other in raw terms. However, for UK investors, CGT-exempt coins (Sovereigns and Britannias) often deliver better net returns after tax. Gold bars give you slightly more gold for your money upfront due to lower premiums.
Are gold bars better than coins?
Gold bars are better in three specific ways: lower premiums per gram, more compact storage, and simpler bulk investing. However, coins win on liquidity, CGT efficiency, divisibility, and authentication. For most UK investors, coins offer more advantages.
Are gold coins worth more than gold bars?
Per gram, gold coins typically cost more to buy than gold bars because of their higher premiums. However, their face value (legal tender status), recognisability, and CGT exemption mean they often retain better resale value, especially in smaller transactions.
Is it easier to sell gold coins or bars?
Gold coins are easier to sell, for two reasons. First, they’re instantly recognisable — a Sovereign or Britannia can be verified by sight, weight, and basic testing. Second, they’re divisible — you can sell one or two coins from a larger holding instead of an entire bar.
Why are gold bars cheaper than coins?
Gold bars carry lower premiums because they’re simpler to produce — no intricate minting, no legal tender status, no fractional sizes. Mints invest heavily in coin designs, security features, and packaging, all of which add to the coin’s premium over the spot gold price.
Should I buy gold bars or coins for my first gold purchase?
For first-time UK investors, we recommend starting with gold Sovereigns or fractional Britannias (1/4oz or 1/2oz). They’re affordable entry points, easy to authenticate, CGT-free, and instantly tradable. You can scale up to bars later once you’re comfortable.
What is the best size gold bar to buy?
For most UK investors, 100g gold bars hit the sweet spot. They offer reasonably low premiums (2-3% over spot), they’re still affordable for individual investors (around £8,000-£9,500 depending on price), and they’re easy to store and resell.
Do gold coins or bars hold value better?
Both track the gold spot price almost identically over the long term. The difference is in transaction costs (premiums) and tax treatment. Net of UK tax, CGT-exempt gold coins generally hold value better for individual UK investors.
Can I buy both gold bars and coins?
Yes — and for portfolios over £20,000, this is often the smartest approach. A typical balanced strategy is 60-80% in CGT-free UK coins for tax efficiency, with 20-40% in larger bars for lower premiums. This combines the strengths of both.
Final Verdict: Gold Bars vs Gold Coins for UK Investors
There’s no single right answer to the gold bars vs gold coins question — but for most UK investors, gold coins (specifically Sovereigns and Britannias) offer the better overall package. Here’s why:
- Complete exemption from Capital Gains Tax (potentially saving thousands)
- Instant global recognition and easy authentication
- Flexibility to sell in small portions when needed
- Easier inheritance and gifting
- Strong secondary market demand
Gold bars still have their place — especially for larger lump-sum investments, SIPP holdings, or as a cost-efficient supplement to a CGT-free coin portfolio. The smartest UK investors typically hold both, with the coins forming the foundation.
Whatever you decide, the most important thing is to buy from a trusted, long-established UK bullion dealer with LBMA-approved sourcing and a verifiable trading history. Cheap gold from unverified sources is often the most expensive mistake a new investor can make.
