1/2oz Britannia Gold Coin

1/2oz Britannia Gold Coin | Royal Mint 999.9 Fine Gold

The 1/2oz Britannia Gold Coin is the largest fractional format in the Royal Mint Britannia family, containing half a troy ounce (15.55g) of 999.9 fine gold. At this size, the coin holds more than double the pure gold of a Full Sovereign (7.32g) while keeping the same UK legal-tender status, Britannia design recognisability, and well-known Capital Gains Tax discussion that apply across the full Britannia range.

This coin suits buyers who want a substantial Britannia holding without committing to the full 1oz price — offering the same iconic design, Royal Mint quality, and 999.9 purity as the 1oz Britannia in a more accessible format. Compare this coin with the 1/4oz Britannia for a lower entry point, or the 1oz Britannia for the standard bullion benchmark. For a best-value alternative at this weight, compare with the 1/2oz Best Value coin.

Why Buyers Choose This Coin

• UK legal tender with CGT discussion: as a British legal-tender coin, the Britannia carries a well-known Capital Gains Tax discussion that many UK buyers find relevant.
• Flexible budget stepping stone: offers a meaningful half-ounce allocation without the full 1oz commitment, making it practical for phased portfolio building.

What to Compare Before Buying

When choosing a half-ounce UK coin, buyers typically compare Britannia versus Sovereign family at this weight, named-mint versus best-value pricing, coin versus bar format, and whether to buy one 1/2oz or two 1/4oz coins for greater flexibility. The 1/2oz Britannia suits buyers who want the largest fractional Britannia with full Royal Mint identity and legal-tender status. For the ultimate Britannia, step up to the 1oz Britannia.

If you are deciding between coins and bars, our guide to the best gold bar size to buy explains how bars differ on premium efficiency. The 1/2oz Best Value bar and 1/2oz PAMP bar offer the same gold weight in bar format. View the full coin range on the Buy Gold Coins UK page. For purity, see our UK gold hallmarks guide.
