British Gold Britannia Guide
The Gold Britannia is the United Kingdom's flagship gold bullion coin, produced by The Royal Mint since 1987. It was 22-karat until 2012 and has been struck in .9999 fine gold since 2013, which means modern Britannias meet the IRS purity standard for IRAs while most older dates do not.
The Britannia's Two Eras
The Royal Mint introduced the Gold Britannia in 1987 as Britain's answer to popular foreign bullion coins. From the start it contained one troy ounce of gold in the one-ounce size, but it used a 22-karat (.9167) alloy, much like the American Gold Eagle and the Krugerrand. The alloy originally included copper; from 1990 the Mint switched to silver as the alloying metal, giving the coin a brighter yellow tone.
In 2013 the Royal Mint moved the Britannia to .9999 fine, or 24-karat, gold. That change aligned it with the Canadian Maple Leaf, the Austrian Philharmonic and other pure gold coins and broadened its appeal to buyers who prefer four-nines purity.
| Period | Purity | Alloy |
|---|---|---|
| 1987–1989 | .9167 (22-karat) | Gold and copper |
| 1990–2012 | .9167 (22-karat) | Gold and silver |
| 2013 onward | .9999 (24-karat) | Essentially pure gold |
Design and Symbolism
Britannia, the female figure personifying Britain, has appeared on British coins since Roman times. The standard bullion design shows her standing with a trident, a shield and an olive branch, with her helmet and flowing robes facing the wind. The design by Philip Nathan has been used on the bullion coin for most of its history, with occasional alternate designs on proof and collector issues. The obverse carries the reigning monarch: Queen Elizabeth II on coins through 2022, with King Charles III appearing on newer issues.
Security Features Added in 2021
In 2021 the Royal Mint redesigned the bullion Britannia with several anti-counterfeiting elements, according to the Mint:
- Latent image: a small symbol that changes between a padlock and a trident as the coin is tilted.
- Surface animation: background waves that appear to move under light.
- Micro-text: very small lettering around the edge of the design.
- Tincture lines: fine lines on the Union flag on Britannia's shield.
These features make high-quality fakes harder to produce. They do not replace basic checks of weight and dimensions; see how to spot fake gold and silver.
Sizes
The one-ounce coin is the standard bullion product. The Royal Mint also offers fractional sizes, including half, quarter and tenth ounce, and has produced smaller and larger collector formats in some years. As with all coins, the smaller sizes typically carry higher premiums per ounce; see our page on fractional gold coins.
Britannias and U.S. Retirement Accounts
Under Section 408(m) of the Internal Revenue Code, gold bullion can be held in an IRA if it meets the fineness standard of a regulated futures market, which for gold is .995. Post-2013 Gold Britannias at .9999 clear that bar. Pre-2013 coins at .9167 do not, and unlike the American Gold Eagle they are not named in the statute, so custodians generally will not accept them.
If you are buying Britannias for an IRA, ask for the year and purity on the invoice so the custodian can confirm eligibility. Our guide to IRS purity standards and our list of IRA-eligible gold coins give more detail.
A Note on UK Tax Treatment
The Royal Mint points out that because Britannias are UK legal tender, gains on them are generally exempt from Capital Gains Tax for UK residents. That rule applies in the United Kingdom only. For U.S. taxpayers, the IRS treats gold coins as collectibles, and long-term gains can be taxed at up to 28%. The legal-tender feature is discussed further in our page on legal tender bullion coins. Speak with a licensed tax professional about your own situation.
Buying Britannias
Britannias are widely traded in the UK and Europe, and many U.S. dealers stock them. When comparing quotes, confirm whether the coin is the current .9999 bullion version, an older 22-karat date, or a proof, since those carry very different pricing.

Frequently Asked Questions
When did the Gold Britannia become pure gold?
In 2013. Coins from 1987 through 2012 are 22-karat.
Can I put a 2005 Gold Britannia in an IRA?
Generally no. Its .9167 purity is below the .995 standard, and it does not have the statutory exception that American Eagles have.
How can I tell a 2021 or later Britannia from older coins?
Newer coins show the latent padlock-and-trident image and animated wave background added in 2021.
Does the UK tax exemption apply to Americans?
No. It is a UK rule for UK residents. U.S. taxpayers follow IRS rules for collectibles.
