Gold Britannia Value Calculator
The gold Britannia contains exactly one troy ounce of 999.9 fine gold, so its melt value tracks the spot price almost one-for-one. Fractional sizes contain a proportional fraction of an ounce.
Britannias are CGT-free UK legal tender and VAT-free investment gold, which is why they are the default one-ounce choice for British gold buyers.
How it’s calculated: live spot price (GBP per troy ounce) ÷ 31.1035 × purity × weight. See our methodology for data sources and update frequency.
