Gold Britannia
The Royal Mint’s flagship modern gold coin, struck since 1987 and upgraded to 99.99% purity in 2013. Britannia offers UK investors the rare combination of full Capital Gains Tax exemption AND U.S. IRA eligibility — making it the most tax-efficient gold coin in the world.

The 2013 Purity Change
The Britannia is unique among modern gold coins because it had a major purity upgrade. From 1987 to 2012, Britannias were struck at 22 karat (91.67% pure) — the same as American Eagles and Krugerrands. Starting in 2013, the Royal Mint upgraded the Britannia to 24 karat (99.99% pure), making it the equivalent of the Canadian Maple Leaf or Austrian Philharmonic.
This is a critical distinction for U.S. buyers planning to use Britannias in a precious metals IRA:
| Era | Purity | IRA Eligible? | Best For |
|---|---|---|---|
| 1987-2012 | 22K (91.67%) | No | UK personal holding, historical interest |
| 2013-present | 24K (99.99%) | Yes | UK or U.S. IRA, modern bullion stacking |
The Britannia Tax Combination
The modern (2013+) Britannia is the most tax-efficient gold coin available. It uniquely combines UK Capital Gains Tax exemption with U.S. IRA eligibility — no other coin does both.
Compare the tax position across major coins:
| Coin | UK CGT | UK VAT | U.S. IRA |
|---|---|---|---|
| Britannia (2013+) | Exempt | Exempt | Eligible |
| Sovereign | Exempt | Exempt | Not eligible (22K) |
| American Gold Eagle | Taxable | Exempt | Eligible |
| Canadian Maple Leaf | Taxable | Exempt | Eligible |
| Krugerrand | Taxable | Exempt | Not eligible (22K) |
For UK investors planning a long-term gold position with potential US-IRA transfer or international flexibility, the modern Britannia is uniquely positioned.
Security Features
The Royal Mint has progressively added anti-counterfeiting features to the Britannia. As of 2021, modern Britannias have four overlapping security features — the most of any gold bullion coin in the world.
Surface Animation
Added 2017. Britannia’s trident appears to move from solid to broken when tilted, due to micro-engraved patterns. Visible to the naked eye, impossible to counterfeit with standard methods.
Latent Image
A padlock symbol becomes visible under specific lighting angles, separate from the surface animation. Requires precision die-cutting only the Royal Mint possesses.
Micro-Text
The word “DECUS ET TUTAMEN” (Latin for “an ornament and a safeguard”) is micro-engraved at sub-millimeter scale. Visible only under magnification.
Tincture Lines
Britannia’s shield uses parallel lines that indicate heraldic colors — a traditional design feature that’s hard to reproduce at this scale and precision.
Combined, these features make the modern Britannia arguably the most secure gold coin in the world. The Royal Mint claims no genuine fake Britannias have been documented since the 2017 introduction of surface animation.
History of the Britannia
The Britannia figure has been on British coinage since Roman times, but the modern Britannia gold bullion coin debuted in 1987. The Royal Mint introduced it as a direct response to the success of the Krugerrand, Maple Leaf, and Eagle — the UK needed a competitive modern bullion offering.
Designer Philip Nathan created the original reverse — a striking image of Britannia, the personification of Britain, holding a trident and shield, standing on a rocky shore. The design has been refreshed several times (1989, 1997, 1999, 2001) with different artistic interpretations, but Britannia herself has remained the central figure.
From 1987 to 2012, the coin was struck at 22 karat purity, matching the Sovereign’s “crown gold” standard. The 2013 upgrade to 99.99% purity was a strategic move by the Royal Mint to compete in the global IRA market — at that time, US Gold IRA inflows were growing rapidly and required 99.5%+ purity coins.
Today, the Britannia is among the top 5 most-traded modern gold coins in the world. Annual mintage typically exceeds 500,000 ounces.
Premium Over Spot
Britannia premiums are comparable to other major 24K coins (Maple Leaf, Philharmonic), reflecting the high security features and UK production costs.
Typical premiums (above pure gold melt value):
- 1 oz Britannia: $65–$120 over spot (2–4% premium)
- 1/2 oz Britannia: $55–$95 over spot (4–7% premium)
- 1/4 oz Britannia: $40–$75 over spot (6–10% premium)
- 1/10 oz Britannia: $25–$45 over spot (10–15% premium)
Pre-2013 (22K) Britannias often trade at slightly lower premiums than post-2013 versions because they’re less in demand (not IRA-eligible). If you don’t need IRA eligibility, pre-2013 Britannias can be a cost-effective buy — same gold content for 1-2% cheaper.
Where to Buy
UK and U.S. dealers both carry Britannias. UK dealers offer lower prices for UK buyers (no import duties).
- Official source
- Authenticated provenance
- Higher premiums but guaranteed
- Free UK shipping
- Competitive premiums
- Wide year selection
Resale & Buyback Value
Modern Britannias have excellent international liquidity, especially in the UK and U.S. markets. Pre-2013 versions are slightly less liquid in the U.S. (not IRA-eligible) but trade actively in the UK.
Buyback expectations:
- UK online dealer (2013+): 96–102% of spot (best price)
- UK coin shop: 92–99% of spot
- U.S. dealer (2013+ only): 95–101% of spot
- U.S. dealer (pre-2013): 90–97% of spot (slightly lower)
- Pawn shop: 70–88% of spot (avoid)
For UK investors, Britannia buyback rates are among the best of any coin due to high domestic demand and tax-free status. For U.S. investors, only 2013+ Britannias get full IRA-grade dealer pricing.
Frequently Asked Questions
Why are pre-2013 and post-2013 Britannias different?
The Royal Mint upgraded the Britannia from 22K (91.67% pure) to 24K (99.99% pure) starting with the 2013 issues. This was done specifically to qualify for U.S. Gold IRAs, which require 99.5%+ purity. Pre-2013 Britannias are still excellent gold coins but cannot be held in IRS-approved retirement accounts.
Are Britannias tax-free in the UK?
Yes. Like Sovereigns, Britannias are UK legal tender, making them fully exempt from UK Capital Gains Tax. They’re also VAT-exempt as investment gold. This applies to all Britannias regardless of year (1987-present).
Can I put Britannias in a U.S. Gold IRA?
Yes, but only 2013-and-later Britannias (99.99% pure). Pre-2013 Britannias (22K, 91.67% pure) don’t meet IRS requirements. Always confirm the year with your dealer before IRA purchase.
What makes Britannia security features special?
The Royal Mint’s 4-layer system (surface animation, latent image, micro-text, tincture lines) is the most extensive on any gold coin. No documented counterfeits exist since 2017. Combined with weight verification, this makes Britannia exceptionally hard to fake.
How much gold is in a 1 oz Britannia?
For 2013+ Britannias: exactly 1 troy ounce (31.10 grams) of pure gold. The coin weighs 31.10 grams total because there’s no alloy. For pre-2013 Britannias: 31.10 grams of pure gold in a coin weighing 33.93 grams (the rest is alloy).
Are Britannias a good investment?
For UK investors, yes — they offer the best after-tax returns on physical gold thanks to CGT exemption. For U.S. investors with IRA accounts, 2013+ Britannias are also excellent. Premiums are competitive with other 24K coins, security features add confidence, and global liquidity is strong.
What’s the difference between Britannia and Sovereign?
Both are Royal Mint UK coins with the same CGT/VAT exemptions. Differences: Britannia is 1 troy oz, Sovereign is 7.32g (less than 1/4 oz). Britannia is 24K post-2013, Sovereign is always 22K. Britannia is IRA-eligible (post-2013), Sovereign is not. Britannia has modern security features, Sovereign does not.
Why does Britannia have a £100 face value?
The £100 face value was chosen at launch (1987) to reflect a higher denomination commensurate with modern coin values. Like all bullion coins, the face value is nominal — you’d never spend a Britannia at £100 when its gold content is worth $4,000+. The face value matters for legal tender status, not actual purchasing power.
