Compare 1oz Britannia Prices

The most-compared bullion coin in the UK

The 1oz Britannia is, by some margin, the default UK bullion coin — the size and design that anchors most retail gold and silver portfolios. Premiums on this format are competitive, every UK dealer stocks both metals, and the dual VAT/CGT exemption (on gold) means no foreign 1oz coin matches its tax position for UK residents.

Specifications across both metals

The 1oz gold Britannia weighs 31.21g overall, contains exactly one troy ounce of pure gold at 9999 fineness, measures 32.69mm in diameter, and carries a £100 face value. The 1oz silver Britannia weighs the same, contains one troy ounce of 999 fine silver, measures 38.61mm, and carries a £2 face value. Both qualify as UK legal tender and both inherit CGT exemption from that status.

Why premium comparison matters most at this size

Because the 1oz Britannia is so heavily traded, premiums vary meaningfully between dealers — sometimes by £20 or more on a single coin. For investors building a multi-coin position, the cumulative premium difference becomes the single largest factor in deployment efficiency. This is exactly the case where active price comparison pays back.

Tax treatment

Gold 1oz Britannias are VAT-exempt as investment gold and CGT-exempt as UK legal tender. Silver 1oz Britannias carry 20% VAT on purchase but retain CGT exemption — a structural advantage over silver bars. See 1oz gold Britannias or 1oz silver Britannias for metal-specific filtering.
