Sterling and the metal price
This page converts the USD spot reference into pounds using a daily currency reference. A sterling gold price can rise when the dollar gold price stays unchanged if a dollar buys more pounds. It can also fall while USD gold rises when sterling strengthens enough. Use the metal/FX scenario calculator to separate these two effects instead of assuming that the USD chart describes the same movement as a GBP dealer quote.
Reading a Britannia specification
The Royal Mint identifies the 2026 one-ounce gold Britannia by one troy ounce of pure metal content and 999.9 fineness. The product’s fine content is the starting point for a spot comparison, while the seller’s actual price includes the commercial terms of that purchase. Fractional coins need their stated fine quantity rather than an assumed one-ounce value. Check the exact issue and size before entering a quantity.
Worked currency conversion
This example assumes gold at USD 3,100 per troy ounce and a conversion of 1 USD = 0.75 GBP. These are illustrative inputs, not current prices or exchange rates. The fine-gram result is 3,100 × 0.75 / 31.1034768 = 74.7505 GBP. Multiply by fine grams to value a holding; add actual fees to compare a purchase.
Before comparing an offer
- Confirm the currency code and whether the quote is per gram, troy ounce or kilogram.
- Establish whether quantity describes gross weight or fine-metal content.
- Request the dealer’s buy and sell quotes separately, including delivery and total fees.
- Match timestamps; daily FX conversions and a live USD chart can describe different observations.
