One of the most frequently asked questions from investors is whether to buy gold bars or gold coins. The answer ultimately depends on your individual objectives, budget and long-term strategy. There is no universally "right" choice — the most suitable option will vary depending on your circumstances.
Gold Bars vs Gold Coins: Premiums
The premium is the amount charged above the live gold spot price. It covers manufacturing, minting, distribution, handling, insurance and dealer margins. Even the most competitive bullion dealers must purchase gold above spot, so premiums are unavoidable.
Generally, gold bars attract lower premiums than gold coins — particularly in larger sizes. This is because bars are simpler and more cost-effective to manufacture. For example, buying a single 1kg gold bar is usually more economical per gram than purchasing ten 100g bars.
Larger bars are therefore well suited to investors who:
- Are committing substantial capital
- Intend to hold for the long term
- Do not anticipate needing to sell part of their holding
However, this cost efficiency comes at the expense of flexibility. Selling a portion of your investment is far easier when holding smaller units. At the 1oz level and below, premiums between bars and coins tend to be similar. From 100g upwards, bars usually offer a lower premium per gram than coins.
Flexibility
Most investors purchase gold and silver bullion to preserve wealth and generate long-term returns. While larger bars typically offer the lowest premiums at the point of purchase, they do not always provide the greatest flexibility when it comes time to sell.
Smaller units — such as 1oz, 50g and 100g gold bars — and particularly gold and silver coins, offer far greater resale flexibility. This can be advantageous if you need to release part of your investment for liquidity, rebalance your portfolio, or phase sales over time to optimise returns.
For example, if an investor holds a single 1kg gold bar representing a large proportion of their liquid wealth, they would need to sell the entire bar to access funds. By contrast, if that same investment were split into ten 100g bars or multiple coins, part of the holding could be sold while retaining the remainder.
Capital Gains Tax Considerations
Gold coins offer even greater versatility. Available in sizes such as 1oz, 1/2oz, 1/4oz and 1/10oz, they are easy to store, simple to trade and highly liquid.
Popular choices include:
- South African Krugerrands — known for competitive premiums
- British Sovereigns and Half Sovereigns — CGT exempt for UK residents
- Gold Britannias — CGT exempt, strong liquidity
For maximum flexibility at lower value points, silver coins — typically 1oz — are also widely used by investors. Silver Britannias, Maples and Philharmonics are among the most popular options.
