What a gold Britannia is made of
The 1oz gold Britannia carries exactly one troy ounce of fine gold, the figure that drives its value.
- Fine gold content: 1.000 troy oz (31.1035g)
- Purity: 1987–2012 coins are 22 carat (916.7); 2013 onwards are 999.9 fine 24 carat
- Either way the coin contains a full ounce of gold; the earlier 22ct coins simply weigh slightly more in total
- Fractional sizes also exist: 1/2oz, 1/4oz and 1/10oz, worth the matching fraction of a full ounce
What a Britannia is worth
Because a 1oz Britannia holds exactly one ounce of gold, its gold value is the gold price.
| Britannia size | Fine gold | Value at £3,600/oz (illustrative) |
|---|---|---|
| 1oz | 1.000 oz | £3,600 |
| 1/2oz | 0.500 oz | £1,800 |

The Britannia’s tax advantage
The gold Britannia is UK legal tender, so it is exempt from Capital Gains Tax for UK residents. There is no CGT on any gain when you sell, whatever the amount. That makes it one of the most efficient gold coins for a UK seller to hold and to sell. GoldPaid is not a tax adviser; check with HMRC if your situation is complex.
When a Britannia is worth more than its gold
- Proof Britannias from The Royal Mint, boxed with a certificate, carry a premium over bullion coins.
- Early dates and certain low-mintage years are collected.
- Condition. An unmarked, capsule-kept coin is worth more to a collector than a scratched one.
Most bullion Britannias trade close to their gold value, which makes them quick and straightforward to sell.
