Bullion means precious metal held in a form that is valued mostly by weight, purity and market price. A one ounce gold coin, for example, is not valued like loose change. Its value is mainly linked to the amount of fine gold it contains.
Most new buyers start with gold or silver bullion coins because they are recognisable, easy to store and easier to sell than obscure products. Bars can offer a lower premium per gram, especially in gold, but coins are often more flexible for collectors and private buyers.
What counts as bullion?
Bullion is usually a refined precious metal product made to a known weight and purity. The most common bullion metals are gold and silver, although platinum and palladium bullion also exist.
The key point is that bullion is bought mainly for its metal content. A bullion coin may have a face value, a famous design and collector appeal, but the starting point for its price is still the value of the precious metal inside it.
Common bullion metals
Gold: compact, high value, widely recognised and popular for long-term wealth storage.
Silver: lower cost per ounce, popular with stackers, but bulkier to store at higher values.
Platinum: less common than gold and silver, with a market influenced by both investment and industrial demand.
Palladium: more specialist, often less suitable for beginners due to spread and liquidity considerations.
Bullion coins, bars and rounds
Bullion comes in several forms. The right choice depends on your budget, storage, collecting style and how easy you want it to be to sell later.
Type
What it is
Best for
Bullion coins
Coins issued by official mints with a stated weight and purity.
Beginners, collectors, recognisable products and flexible resale.
Bullion bars
Precious metal bars made by mints or refiners, often available in many sizes.
Lower premiums, compact gold storage and building weight efficiently.
Rounds
Coin-shaped bullion pieces that are not legal tender.
Silver stackers who want simple metal exposure without focusing on official coin status.
Collector tip
For a first purchase, recognisable coins such as Britannias, Sovereigns, Krugerrands, Maple Leafs and Eagles are usually easier to understand than unusual private mint products.
How bullion gets its value
The core value of bullion comes from weight, purity and the current market price of the metal. A one ounce gold coin contains one troy ounce of fine gold if it is sold as a one ounce fine gold product. A one kilo silver bar contains one kilogram of silver, normally at a high stated purity.
However, bullion rarely sells exactly at the raw metal price. Buyers usually pay a premium above the metal value, and sellers may receive slightly below or above spot depending on the product, condition, dealer, demand and market conditions.
The main value factors
Metal: gold, silver, platinum and palladium have different prices and market behaviour.
Weight: larger products usually contain more metal and may have a lower premium per gram.
Purity: many modern bullion products are 999 or 999.9 fine, but some classic coins use different alloys.
Recognition: well-known coins and bars can be easier to sell.
Condition: bullion does not need to be perfect, but damage can affect desirability.
Demand: popular series can carry higher premiums when supply is tight.
Spot price and bullion premiums
The spot price is the live wholesale market price for a precious metal. It is the starting point for bullion pricing, but it is not usually the price a private buyer pays for a finished coin or bar.
A premium is the amount above the metal value. It covers production, minting, distribution, dealer margin, delivery, market demand and sometimes collectability.

Typical premium behaviour
Why
Large gold bars
Often lower premium per gram
Efficient production and high metal value in one item.
Small gold bars
Often higher premium per gram
More manufacturing and handling cost relative to the metal value.
Silver coins
Often higher percentage premium than gold
Lower metal value per item means fixed costs matter more.
Limited or popular coins
Can carry extra premium
Demand, mintage, design and collector interest can affect price.

UK buyers should understand tax treatment before choosing between coins and bars. Investment gold is generally VAT exempt in the UK when it meets the relevant investment gold rules. Silver bullion is normally different and is commonly sold with VAT included unless using a specific storage or margin scheme setup.
Capital Gains Tax treatment can also matter. Many Royal Mint bullion coins are UK legal tender, which is why they are commonly described as CGT exempt for UK residents. This is one reason UK buyers often favour Sovereigns and Britannias over some foreign coins or bars.
Tax rules can change and personal circumstances differ, so this guide is for general education rather than tax advice.
Before buying your first bullion
A good first purchase should be simple, recognisable and easy to understand. Most beginners are better served by learning the basics than chasing rare designs, very low mintages or complicated graded products straight away.
Compare the total price, not just the headline metal price.
Check the premium above spot before buying.
Use recognised dealers and keep purchase records.
Think about storage before the collection grows.
Decide whether you are stacking weight, collecting series or doing both.
Track what you own so cost, weight and value do not become guesswork.
Frequently asked questions
Is bullion the same as jewellery?
No. Jewellery can contain precious metal, but it is usually valued through design, brand, craftsmanship and retail margin as well as metal content. Bullion is normally bought much closer to its precious metal value.
Are bullion coins legal tender?
Some bullion coins are legal tender in their issuing country, but they are not bought for everyday spending. Their metal value is usually far higher than their face value.
Are bars cheaper than coins?
Bars can have lower premiums, especially larger gold bars. Coins may be easier to sell in smaller amounts and can have extra advantages for UK buyers when they are Royal Mint legal tender coins.
What is the best bullion for beginners?
Recognisable bullion coins are often the easiest starting point. In the UK, many beginners compare Britannias, Sovereigns, Krugerrands, Maple Leafs and Eagles before buying.
