Understanding Sovereign Premiums
The Full Sovereign (7.988g, 22 carat) has been minted by the Royal Mint since 1817 and remains one of the world's most recognized bullion coins. Because it's smaller than a standard 1 oz coin, its premium as a percentage of gold content is naturally higher — minting costs don't scale down proportionally with coin size.
Typical Premium Ranges (2026)
| Coin | Typical Premium |
|---|---|
| Britannia 1 oz | 3-6% |
| Full Sovereign | 6-10% |
| Half Sovereign | 12-18% |
Why Sovereigns Are Popular with UK Investors
- CGT-Free: As UK legal tender, Sovereigns and Britannias are exempt from Capital Gains Tax on profit.
- VAT-Free: Investment-grade gold coins are exempt from VAT in the UK.
- Historic & Liquid: Sovereigns are recognized and easily resold by dealers worldwide, not just in the UK.
- Small Denominations: Half and Full Sovereigns make it easier to buy or sell smaller amounts of gold without breaking a full ounce.
Frequently Asked Questions
How much gold is in a Full Sovereign?
A Full Sovereign weighs 7.98805 grams at 91.7% purity (22 carat), containing 0.2354 troy ounces of fine gold. A Half Sovereign weighs 3.99403 grams, containing 0.1177 troy ounces of fine gold.
Are Sovereigns CGT (Capital Gains Tax) free in the UK?
Yes. Gold Sovereigns and Britannias minted from 1837 onwards are legal tender in the UK, which makes them exempt from Capital Gains Tax on any profit when sold — a major advantage over gold bars or foreign coins.
Why do Half Sovereigns have a higher premium than Full Sovereigns?
Minting costs (striking, packaging, distribution) are largely fixed per coin regardless of size, so smaller coins carry a higher premium as a percentage of their gold content. A Half Sovereign typically costs more per gram of gold than a Full Sovereign.
What's a fair premium for a Britannia 1 oz coin?
Britannia 1 oz coins (.9999 pure) typically carry a premium of 3-6% over spot, similar to other major 1 oz bullion coins like the Maple Leaf or Kangaroo, since they're minted in high volume by the Royal Mint.
