Royal Arms Platinum

The Royal Arms Platinum Coin

The Royal Arms is one of The Royal Mint's core bullion coin ranges, featuring Timothy Noad's heraldic reinterpretation of the United Kingdom's Royal coat of arms. Introduced in 2019, the platinum version of the 1 oz coin carries 999.5 fineness and UK legal tender status with a GBP 100 face value. The 2025 edition marks the seventh consecutive year of the same design, which The Royal Mint has described as its "final appearance" in this form, suggesting either a redesign or series conclusion.

For UK platinum investors, the Royal Arms' primary appeal is its tax position. As UK legal tender, the coin is CGT-exempt on disposal, meaning any capital gain on sale is not subject to Capital Gains Tax. This exemption is shared with The Royal Mint's Platinum Britannia and the themed series coins (like the Robin Hood), but not with any foreign platinum coin. Given that platinum attracts 20% VAT on purchase in the UK, the CGT exemption on the exit side is a meaningful advantage in the overall cost equation.

The Royal Arms heraldic shield has appeared on British coinage for centuries, with the quartered design featuring England's three lions (first and fourth quarters), Scotland's lion rampant (second quarter), and Ireland's harp (third quarter). Noad's modern interpretation adds the four national symbols of the United Kingdom around the central shield: the leek (Wales), shamrock (Northern Ireland), Tudor rose (England), and thistle (Scotland). A radial line background creates both visual depth and an anti-counterfeiting feature, as the precise spacing is difficult to replicate.

Unlike The Royal Mint's Britannia, which receives advanced security features including latent images, surface animation, tincture lines, and micro-text, the Royal Arms relies on its radial line background and standard Royal Mint minting quality for authentication. This simpler security profile may contribute to marginally lower premiums compared to the Britannia, though both coins share the same fundamental tax and purity characteristics.

Available Formats Across Metals

The heraldic design by Timothy Noad, one of the UK's foremost heraldic artists, was created specifically for the bullion range. The quartered Royal coat of arms occupies the centre, surrounded by the four national plant symbols. The radial line background extends across the entire field, creating a shimmering visual effect that varies with viewing angle. The obverse transitioned from Queen Elizabeth II to King Charles III following the 2022 monarch change.

Royal Arms Platinum Tax Treatment by Country

The Royal Arms' UK legal tender status provides specific tax advantages that distinguish it from foreign platinum coins across several jurisdictions.

• United Kingdom: Platinum coins attract 20% VAT on purchase (no investment platinum exemption exists). On disposal, the Royal Arms is CGT-exempt as UK legal tender under HMRC rules. This exemption applies to both gold and silver Royal Arms coins as well. Gold versions are additionally VAT-free on purchase (investment gold zero-rating). Silver versions carry 20% VAT (margin scheme at approximately 5-8% may apply through certain dealers). The CGT exemption makes Royal Arms and Britannia platinum coins the most tax-efficient options for UK residents holding platinum for potential gain.
• United States: The coin's 999.5 purity exceeds the IRS 99.95% minimum for platinum IRA eligibility. As a sovereign-minted coin from a recognised government, it qualifies for IRA inclusion through approved custodians. State sales tax exemptions for precious metals vary by state, with approximately 35 states exempting bullion.
• European Union: Investment gold coins are VAT-exempt across the EU. The Royal Mint's gold coins appear on the EU annual exemption list. Silver and platinum versions are subject to local VAT rates (17-27% depending on country).
• Canada: Platinum at 99.5% purity or above is GST/HST-exempt. The Royal Arms qualifies. RRSP eligibility is supported by the purity standard. Capital gains follow the 50% inclusion rate.
• Australia: Platinum coins at 99% purity or above are GST-free. Capital gains tax applies with a 50% discount for individual holdings exceeding 12 months.
• New Zealand: Platinum at 99% purity or above is GST-exempt. No capital gains tax.
• Singapore: Platinum coins at 99% purity that are or were legal tender qualify as IPM, exempt from 9% GST. No capital gains tax.
• Hong Kong: No sales tax, import duty, or capital gains tax on any precious metal.

Royal Arms Platinum vs Britannia and International Alternatives

The Royal Arms sits in a specific competitive position: a mid-tier Royal Mint bullion coin with UK CGT exemption, simpler than the Britannia but carrying the same fundamental tax benefits.

The Platinum Britannia is the most direct competitor and the stronger product by most measures. The Britannia has wider international recognition, more advanced security features (latent image, surface animation, tincture lines, micro-text), and a larger dealer network. Both share 999.5 purity, UK legal tender status, and CGT exemption. The Royal Arms' potential advantage is marginally lower premiums in some market conditions, reflecting its simpler security profile and lower brand premium. For UK buyers whose primary concern is CGT-exempt platinum at the lowest available premium, the Royal Arms may occasionally undercut the Britannia.

The Gold Sovereign shares CGT exemption and centuries of history, but at 7.32 g (0.2354 oz) the Sovereign is not available in a standard 1 oz format. For buyers who specifically want a 1 oz CGT-exempt platinum coin, the Royal Arms competes with the Britannia and The Royal Mint's themed series coins (Robin Hood, Tudor Beasts, Queen's Beasts), not the Sovereign.

Against international platinum coins, the Royal Arms' CGT exemption is its structural advantage for UK residents. The American Platinum Eagle, Platinum Maple Leaf, and Perth Mint Platinum Kangaroo all carry comparable or better specifications and deeper global liquidity, but none can offer UK CGT exemption. For non-UK buyers, the Royal Arms has limited competitive advantage over these established programmes.

The seven-year run of the same design (2019-2025) positions the Royal Arms as a consistent investment product rather than a collector series. Unlike the Queen's Beasts, Tudor Beasts, or Myths and Legends coins, which change designs and generate annual collector interest, the Royal Arms offers the same heraldic motif year after year. This consistency is an advantage for stackers who want uniformity in their holdings and a disadvantage for collectors who value annual variety.
