About the 10 oz Britannia Silver Coin
The Royal Mint's 10 oz Silver Britannia
The 10 oz Silver Britannia combines The Royal Mint's flagship design with a weight class that delivers meaningful premium savings over the standard 1 oz Silver Britannia. At .999 fine silver with a GBP 10 face value, it carries the full suite of benefits that make the Britannia range distinctive: UK legal tender status providing CGT exemption, advanced security features from the 2021 issue onward, and the backing of a mint that traces its origins to 886 AD.
For UK buyers, the CGT exemption is the defining advantage. The 10 oz Britannia is one of the few large-format silver coins where profits on disposal are entirely free from Capital Gains Tax, because UK legal tender coins denominated in sterling are exempt regardless of the metal. This sets it apart from every non-British 10 oz silver coin on the market, including the Perth Mint Kookaburra, RCM Magnificent Maples, and Armenian Noah's Ark.
The 2021 redesign by Philip Nathan introduced four visual security features to the Britannia range: a latent image that shifts between a padlock and trident, surface animation using picosecond laser technology, micro-text reading DECUS ET TUTAMEN, and tincture lines on the shield. These apply across all denominations, making the 10 oz coin one of the most secure large-format silver pieces available from any mint.

The silver Britannia series has evolved significantly since its 1997 introduction. The original coins used Britannia silver at .958 fineness, a historic standard first mandated in England in 1697. In 2013, the purity was upgraded to .999 to align with international bullion standards, and the dimensions changed (the 1 oz coin moved from 40 mm to 38.61 mm diameter). The 10 oz format extends this modern specification to a larger canvas.
The reverse design changes annually, which distinguishes the Britannia from most bullion coins that carry a fixed design. Notable recent designers include Philip Nathan (2021 standing Britannia with security features), Jonathan Olliffe (2023 chariot with sea creatures), and Marie-Alice Harel (2024 profile with helmet, lion, and wave). The obverse transitioned from Queen Elizabeth II to King Charles III from 2023 onward.
Britannia Silver Coin Tax Treatment
The 10 oz Silver Britannia's UK legal tender status creates a distinctive tax profile that separates it from all foreign-minted competitors.
United Kingdom
The headline benefit is CGT exemption. As a coin denominated in sterling and classified as UK legal tender, the Britannia is exempt from Capital Gains Tax on disposal. This applies regardless of the size of the gain or the holding period. For silver investors anticipating significant appreciation, this exemption can offset a substantial tax liability that would otherwise be levied at 18-24% on gains above the GBP 3,000 annual allowance.
On the purchase side, silver coins in the UK carry 20% VAT. The Britannia does not escape this. Some dealers offer silver Britannias under the margin scheme when selling pre-owned stock, reducing the effective VAT to the dealer's margin only. New-minted Britannias from The Royal Mint carry the full 20% VAT. This creates a break-even calculation: the CGT exemption only provides a net benefit if the eventual capital gain exceeds the initial VAT cost.
United States
The 10 oz Silver Britannia is IRA-eligible at .999 fineness, meeting the IRS minimum of 99.9% for silver. Pre-2013 Britannias at .958 fineness would not qualify. Must be held by an approved custodian. Capital gains are taxed at the collectibles rate of up to 28%.
European Union
Silver coins are subject to local VAT rates across the EU (17-27% depending on the country). Some member states apply margin scheme treatment to legal tender silver coins, including Germany (Differenzbesteuerung at effectively 3-7% rather than the standard 19%) and the Netherlands (margeregeling). The Britannia's post-Brexit status does not disqualify it from these provisions as the rules are based on the coin's characteristics, not the issuing country's EU membership.
Other Jurisdictions
- Canada: GST/HST exempt at .999 purity from a recognised government mint.
- Australia: GST-free as investment-grade silver at 99.9% purity.
- New Zealand: GST-exempt at 99.9% purity. No capital gains tax.
- Singapore: GST-exempt as an Investment Precious Metal.
- Hong Kong: No sales tax, duty, or CGT.
10 oz Britannia vs Other Large-Format Silver Coins
The 10 oz Britannia's competitive position rests on one pillar that no competitor can match: UK CGT exemption. Every other comparison point is secondary to this for UK-based buyers.
vs 10 oz Kookaburra (Perth Mint)
The 10 oz Kookaburra offers .9999 purity (versus the Britannia's .999), annual design changes that build collector demand, and the Perth Mint's strong reputation across Asia-Pacific markets. Premiums are comparable. For UK buyers, the Britannia wins on CGT exemption. For Australian buyers, the Kookaburra benefits from local GST-free status and domestic availability. For US buyers choosing between them for an IRA, both qualify on purity grounds.
vs 10 oz Magnificent Maples (RCM)
The 10 oz Magnificent Maples brings .9999 purity, Bullion DNA verification technology, and the Royal Canadian Mint's reputation for refining excellence. Premiums are typically slightly lower than the Britannia. In Canada, the Magnificent Maples has the home-market advantage of GST/HST exemption. The Britannia counters with its UK tax benefits and the design prestige of an annually changing reverse.
vs 10 oz Queen's Beasts (Royal Mint)
The 10 oz Queen's Beasts is a fellow Royal Mint product with identical CGT exemption. The Queen's Beasts series ran from 2016 to 2021 with ten heraldic designs, each a one-year issue. Secondary market premiums on popular designs (Lion, Dragon) have held above current-year Britannia pricing. For buyers indifferent to design, the current-year Britannia typically offers a lower premium. For those seeking both CGT exemption and collector upside, the Queen's Beasts complements or competes depending on availability.
vs 10 oz Armenian Noah's Ark
The 10 oz Noah's Ark is consistently one of the lowest-premium legal tender silver coins available. Its .999 purity matches the Britannia, and its legal tender status enables margin scheme VAT treatment in the UK and EU. The critical difference is CGT: the Noah's Ark is not UK legal tender, so gains are taxable. For UK buyers planning to hold long-term, the Britannia's CGT exemption can more than offset its higher initial premium.
