When it comes to investing in gold, UK investors have a distinct advantage: certain coins are completely free from Capital Gains Tax (CGT). But which coins offer the best combination of value, liquidity, and long-term performance?
In this guide, we break down the best gold coins to buy — from reliable “loose” bullion coins to premium certified coinsthat have consistently outperformed the market.
Why British Investors Should Focus on UK Legal Tender Gold Coins
Before we dive into the top picks, here’s one vital reason to choose carefully:
British gold coins classed as legal tender are exempt from Capital Gains Tax — meaning any profits made when selling are completely tax-free.
This makes coins like the Gold Sovereign, Britannia, and modern Royal Mint collector series far more efficient than bars or foreign coins.
Loose (Uncertified) Gold Coins: Reliable, Flexible, Tax-Efficient
These coins offer excellent value, high liquidity, and tax efficiency — ideal for stacking, diversifying, or gradually building wealth.
