Sell gold sovereign coins by post across the UK

The British gold sovereign has been struck since 1817 to a single technical specification that has barely changed in two centuries: 7.98805 grams gross weight, 22ct gold (916 fineness), giving 7.32238 grams of pure gold per coin, or 0.2354 of a troy ounce. Every full sovereign you can post us, whether minted in 1817 or 2024, contains essentially the same amount of fine gold within tolerance.

The half sovereign is half a full sovereign in every dimension: 3.99 grams gross, 0.1177 troy ounces fine gold. Quarter and double sovereigns also exist but in far smaller numbers, mostly as modern Royal Mint issues for collectors. The XRF reading on arrival confirms each coin's 22ct purity directly; pre-1934 sovereigns are very occasionally slightly under-weight from circulation wear, which the calibrated scale picks up.

A small but significant share of UK sovereigns are worth more than their gold content. The reasons split into three categories: rare date, rare mint, and proof quality.

Rare dates: certain years of the Victorian, Edward VII, George V and the brief Edward VIII sovereign issues are scarce enough to attract collector premiums above scrap. Edward VIII pattern sovereigns (struck but never officially issued in 1937) are the headline example, valued at hundreds of times bullion. More common rare dates like Victorian "shield-back" sovereigns from certain branch mints can run 5-30% above bullion depending on condition.

Rare mints: sovereigns were struck at London, Melbourne, Sydney, Perth, Bombay, Pretoria and Ottawa. The mint mark (a small letter or symbol on the reverse) identifies the branch mint and some branch combinations are scarce.

Proof quality: modern Royal Mint proof sovereigns sold in their original presentation cases carry premiums of 10-30% above bullion when sold complete with the certificate of authenticity.

The vast majority of full sovereigns in UK private hands are common-date Edward VII, George V or modern Elizabeth II issues. None of those carry numismatic premium; they sit at the bullion value, which is simply 7.32 grams of fine gold at the current per-gram rate.

The bullion-value floor matters: even the most common date sovereign in worn condition is worth its measured fine-gold weight, which at recent rates means each full sovereign is worth several hundred pounds. The XRF reading and the scale on arrival give the bullion figure to the penny; the date check determines whether the premium applies on top.

Cleaning is the most common way a UK seller reduces what a sovereign is worth. Decades in a drawer or a purse leave a soft, even surface tone, and that tone is part of how a collector reads a coin as original. A polishing cloth, silver dip, toothpaste or an ultrasonic bath strips it, leaves hairline scratches across the flat fields, and turns a coin that might have carried a premium into one valued on metal alone. It cannot be undone. Gold does not tarnish, so there is nothing that needs removing in the first place; send each coin as it is, in whatever tissue, capsule or case it has lived in.

Two condition points do change the figure, and we are straightforward about both. A sovereign that has been mounted, drilled or soldered has lost its collector market, so it is valued on fine-gold content, and the solder is measured separately because it is usually a lower carat than the coin. A heavily worn coin also weighs slightly less than a sharp one, which the scale records. Neither is a reason to hold a coin back.

Every offer starts from the same floor and adds anything the coin has earned above it. The floor is fine-gold content: grams of pure gold in that coin, multiplied by the per-gram rate on the day the parcel is assessed, which follows the international gold fix and the GBP/USD rate. That part is arithmetic, and it appears on the written offer coin by coin. The wider method is set out in how we value gold.

Above the floor sits any numismatic premium. Each coin is identified by monarch, year, type and mint mark, then checked against current trade guides and realised auction results rather than a fixed internal list. Where a date, a branch mint or an original proof presentation lifts a coin above metal, the premium is shown on its own line so you can see what was added and why. Where nothing applies, the offer says so and the coin sits at fine-gold value. A parcel is never averaged: twelve common George V sovereigns and one scarcer branch-mint coin are thirteen lines, not one bulk weight. If a coin would do materially better through a specialist numismatic route, we say so rather than buying it at metal.

Gold sovereigns are UK legal tender, which puts them in the same position as gold Britannias: gains made by UK individual residents on the disposal of UK legal tender coins are exempt from Capital Gains Tax. HMRC treats sovereigns dated 1837 onwards as currency for this purpose, and the same applies to half and quarter sovereigns.

The exemption is narrower than people assume. It does not cover foreign coins such as Krugerrands or Maple Leafs, and it does not cover gold bars or scrap jewellery, which are chargeable assets measured against the annual exempt amount. On a larger parcel that distinction matters: a bag of inherited sovereigns and the same weight of gold bar can be taxed quite differently on an identical gain.

This is general information for UK residents rather than tax advice. HMRC publishes the underlying guidance on gov.uk, and an accountant can confirm your own position, particularly for inherited coins where the base cost is normally the value at the date of death.

Sovereigns are small (22mm diameter, 1.5mm thick) and need wrapping individually in tissue or a small coin envelope so they do not rub against each other in transit. A parcel of ten full sovereigns weighs only about 80 grams, but ten sovereigns are worth several thousand pounds at recent rates, well above the £2,500 Royal Mail cover. Tell us the number of coins before a label is issued.

Because a single sovereign is worth several hundred pounds, even a handful of coins can take a parcel past £2,500. Tell us how many you have first and we will split the consignment across more than one parcel, each with its own label, tracking number and cover, before any label is sent.
