If you’re thinking about buying physical gold, the choice between a 1 oz gold bar and a 1 oz gold coin might seem like a small detail. But depending on what you pick, it could have a meaningful impact on your returns, especially when it comes to tax, flexibility, and how easy it is to sell when the time comes.
Are 1 oz gold bars a good investment? Are 1 oz gold coins a good investment? We see these questions asked all the time. The good news? At the 1 oz level specifically, neither option is a bad choice. Both give you the same amount of physical gold, both are VAT-free in the UK, and both are globally recognised and easy to trade. The differences come down to your personal circumstances, your investment goals, and (for larger portfolios) some important tax considerations. Let’s break it all down.
Are premiums different at 1oz?
A premium is the additional cost you pay above the live gold spot price, covering manufacturing, handling, and distribution. It’s an unavoidable part of buying physical gold, so it’s worth understanding.
Here’s where it gets interesting. At the 1 oz level, premiums on bars and coins are quite similar. Because coins are minted in very high volumes, their manufacturing costs are lower than you might expect, which makes them competitive with, and sometimes marginally cheaper than, a comparable 1 oz bar.
This changes as you scale up. If you’re buying 100g bars or larger, bars start to offer a clear premium advantage over coins. But at the 1oz level, premium alone shouldn’t be the deciding factor, as there are plenty of other considerations to think about.
The tax advantage coins have over bars
Arguably, this is one of the most important differences, and it’s one many first-time buyers might overlook. All investment gold in the UK is free from VAT, so that’s whether you buy a bar or a coin. However, Capital Gains Tax (CGT) is a different matter altogether.
Gold bars are subject to CGT on any profit you make when you sell. UK gold coins produced by The Royal Mint (including the Gold Britannia and the Gold Sovereign) are legal tender, meaning they’re exempt from CGT. So any profit you make on these coins is yours to keep in full, regardless of how much the gold price has increased.
For investors holding gold over the long-term, or if you’re expecting significant appreciation, this can be a substantial saving. Coins may carry a slightly higher premium in some cases, but it’s worth factoring in the tax advantage to decide what works best for your investment.
Flexibility: Why it matters more than you think
When comparing a 1 oz gold bar vs a 1 oz gold coin, the flexibility is equal. However, it’s when you’re comparing a single weighted gold bar vs multiple coins that flexibility becomes a thought. When it comes to liquidation, coins could potentially provide greater control over when and how much you liquidate, as you can sell smaller amounts one at a time. Owning a heavier gold bar that equates to the weight of numerous coins means you’ll have to sell the whole bar, even if you only wanted to liquidate a percentage of your holdings.
Which is right for you?
Investing has to do with personal finance, right? That means your position will be different to anybody else. Below are some ideas for investors at various stages, however it’s always important to consider what’s right for you. Perhaps you have a financial adviser who could support in creating a plan for your specific gold investments.
First-time investors
If you’re new to buying gold, coins are generally the more forgiving starting point. The CGT exemption on Royal Mint coins means you don’t need to worry about tax on profits, and the ability to sell individual coins gives you options as your financial situation changes.
A popular starting point might be the Gold Britannia, as they’re easy to sell, and carry competitive premiums at the 1 oz level.
Long term, buy-and-hold investors
If your plan is to buy and hold for five, ten, or twenty years without touching your investment, bars might become a more attractive option for you, especially as you scale up in size. A long-term holder buying multiple 1 oz bars now can later reinvest in larger bar sizes like 100g, 250g, 1 Kilogram or more, where premium savings become more significant.
That said, even long-term investors now hold some proportion of their gold in CGT-exempt coins. That’s why a balanced approach between bars and coins could potentially be a strategy that works for you.
The case for long-term holding is well supported. According to the World Gold Council, global investment demand for gold reached a four-year high of 1,180 tonnes in 2024 (a 25% increase year-on-year).
Investors looking to invest larger sums
If you want to invest significant amounts, the bar vs. coin decision takes on a different dimension altogether.
At higher investment levels, every fraction of a per cent in premium becomes meaningful, and larger gold bars can offer savings over coins of the same total weight. However, CGT becomes equally significant.
You might want to consider a blend, where you hold the majority of your gold in larger bars for value efficiency, and supplement with CGT-exempt Royal Mint coins to manage your eventual tax position. Buying mixed-year coins is also worth considering, as specific years can carry a small collector premium that doesn’t add to your investment return.
1 oz gold bars vs gold coins: A quick comparison
| Factor | 1 oz Gold Bar | 1 oz Gold Coin |
|---|---|---|
| Premium | Broadly comparable at 1 oz; lower premiums at larger bar sizes | Broadly comparable at 1 oz; can be marginally cheaper due to high mintage volumes |
| VAT | VAT-free | VAT-free |
| Capital Gains Tax | Subject to CGT on profits | UK Royal Mint coins (Britannia, Sovereign) are CGT-exempt |
| Liquidity | High | High |
| Best for | Long-term, buy-and-hold investors; those scaling up to larger sizes | First-time buyers, tax-conscious investors, those wanting flexibility |
So, which should you choose?
Ultimately, there’s no right or wrong answer, because the best option is the one that works for you. At 1 oz, there are some clear patterns. For example, if you’re starting out, want flexibility, or are tax-conscious, then 1 oz gold coins are a great option. If you’re a long-term holder who plans to scale your investment over time and doesn’t need to access funds in the short term, 1 oz gold bars are also a sound choice.
