Why one sovereign matters more than a tray of jewellery
A gold sovereign is a small coin, roughly the diameter of a five-pence piece, and a charity volunteer can easily mistake it for a foreign curio or a costume-jewellery coin pendant. The reason it matters is straightforward. A sovereign weighs 7.98 grams gross and contains 7.32 grams of 22-carat gold. A mixed jewellery donation of similar weight is usually 9-carat or 14-carat, often hollow, often plated, and often part-set with broken stones. The single sovereign coin contains roughly twice the fine-gold content of the same weight in mixed jewellery, and it has none of the assay ambiguity.
This is why a charity shop team that learns to recognise a sovereign at the sorting stage protects more donated value than one that learns almost any other identification skill. The recognition does not need to be expert. It needs to be good enough to set the coin aside and send a photo on WhatsApp before it goes anywhere near the till or the public floor.
What a sovereign looks like across the reigns
The modern sovereign series starts in 1817 and is still being struck today. For charity-shop purposes the four reigns that turn up most often in donation bags are Victoria, Edward VII, George V, and Elizabeth II. Each reign has a distinct obverse portrait and a near-identical reverse: Saint George on horseback slaying a dragon, designed by Benedetto Pistrucci. If the coin in your hand shows that exact dragon-and-horseman scene on one side, you are looking at either a real sovereign or a deliberate copy of one.
Victorian sovereigns split into three portrait types. Young Head (1838 to 1887), Jubilee Head (1887 to 1893) and Old Head (also called Veiled Head, 1893 to 1901). The Young Head sovereigns are the most varied in design across the reverse and include a shield-back reverse that does not show Saint George. Edward VII sovereigns run 1902 to 1910 and have a clear bare-headed left-facing portrait. George V sovereigns run 1911 to 1932 and are the most common reign by surviving volume. Elizabeth II sovereigns start in 1957 and are struck in modern proof and bullion forms; the laureate young portrait, the decimal-era portrait by Arnold Machin, and the later Ian Rank-Broadley and Jody Clark portraits all appear.
Full sovereign, half sovereign, and the rest of the family
A full sovereign is 22.05mm across and 7.98g. A half sovereign is 19.30mm across and 3.99g, roughly the diameter of a one-pence piece, and contains 3.66g of 22-carat gold. The two are easy to confuse in a sorting tray because the half is not far off the full in apparent size; the weight tells the difference instantly on any kitchen scale that reads to 0.1g.
Quarter sovereigns are a modern series only, starting in 2009. They are 13.5mm across and 1.99g, and appear in proof and bullion sets. Double sovereigns and five-pound gold coins also exist and turn up rarely in charity donations; if a coin looks like a sovereign but is noticeably heavier in the hand, weigh it before posting and include the weight in the WhatsApp message.
Mint marks: S, M, P and the colonial issues
From the late 1800s through the 1930s the Royal Mint authorised branch mints across the British Empire to strike sovereigns to the same specification. The mint of issue is shown by a tiny single letter on the reverse, just above the date and below the horse's hoof on the Saint George design. The four colonial mint marks a charity team is most likely to see are:
- S, Sydney, Australia. Struck 1855 to 1926.
- M, Melbourne, Australia. Struck 1872 to 1931.
- P, Perth, Australia. Struck 1899 to 1931.
- I, Bombay, India. Struck only in 1918, a single-year issue.
- C, Ottawa, Canada. Struck 1908 to 1919.
- SA, Pretoria, South Africa. Struck 1923 to 1932.
A London-struck sovereign has no mint mark in that position. The branch-mint sovereigns are not automatically more valuable than London issues; some specific year-and-mint combinations are scarce and command a premium over the bullion price, while many others trade at the same bullion level. The premium combinations are where a photo to GoldPaid before posting is worth the two minutes it takes, because the price difference can be hundreds of pounds.
Bullion value versus numismatic value
The bullion value of a sovereign is set by the daily gold price. With 7.32g of fine gold in the coin, the bullion floor moves with the London Bullion Market Association (LBMA) PM fix. The numismatic value is anything paid above that bullion floor because of rarity, condition, or collector demand. For most sovereigns the numismatic premium is small. For a small number of specific issues, short-run colonial dates, certain Victorian shield-back sovereigns, proof issues, low-mintage Edward VII colonial dates, the premium can be a multiple of the bullion value.
A charity-shop team does not need to know which dates are scarce. The team needs to know that the answer changes by year and mint, and that a five-minute photo check beats any guess. GoldPaid's indicative figures move with the market; the firm offer is set only after XRF assay confirms purity and weight of the specific coin sent.
Fakes, copies and "sovereigns" set into jewellery
Three categories of not-quite-sovereigns turn up in donations and trip up charity teams. The first is the contemporary forgery, usually struck in lower-carat gold or in base metal with a thin gold plate, intended to deceive. These often show a slightly soft strike, weak detail in the horse's mane, or weights that come in below the genuine 7.98g. A scale that reads to 0.01g is enough to flush most of them out before posting.
The second is the souvenir or restrike, often dated 1925 or 1927 and produced in volume by overseas mints from genuine gold. These are real gold at the correct weight, but they were not struck at the Royal Mint or its authorised branch mints. They retain bullion value but have no numismatic premium, and a buyer who treats them as collector pieces is overpaying. XRF assay distinguishes a restrike from a genuine UK or colonial strike by alloy composition.
The third, and the most common in charity bags, is the sovereign set into jewellery: a sovereign ring, a sovereign pendant, or a sovereign cufflink set. The coin in a sovereign mount is almost always genuine, because the mount was made to take a real coin. The mount itself, however, is rarely gold of the same purity; it is usually 9-carat or 14-carat. The right path is to send the whole item, mount and coin together, and let the assay separate the values.
The Krugerrand parallel and why the principle applies
The same principle that applies to a sovereign applies to a Krugerrand, a Canadian Maple Leaf, an American Eagle and most modern bullion coins. They are coins that contain a defined fine-gold weight, they have a recognisable design, and they have a bullion floor that any charity-shop volunteer can look up. A South African Krugerrand contains one ounce of fine gold; a one-tenth Krugerrand contains a tenth of an ounce. These coins are covered in the foreign gold coins guide in more detail. The point for this guide is that any small heavy yellow coin with a recognisable design is worth flagging, not just a British sovereign.
What to do when a sovereign turns up in the back room
- Set the coin aside in a small envelope, marked with the date and shop. Do not put it in the till, the display case, or on the shop floor.
- Photograph both sides on a plain background, in daylight or under a strong lamp. The date and any mint mark must be readable.
- If you have a kitchen scale, weigh the coin and note the weight in grams.
- Send the photo and the weight to GoldPaid on WhatsApp (07375 071158) with a short note: which charity, which shop, how many coins.
- A response with an indicative figure usually comes back the same day. If you accept it, GoldPaid sends a prepaid Royal Mail Special Delivery label.
- Cover is up to £2,500, higher available on request before posting.
- On arrival the coin is XRF-tested and a written offer is sent. If the offer is accepted before 3pm UK time, payment is by Faster Payments to the charity's registered bank account the same business day.
- If the charity declines the offer, the coin is returned free of charge, insured, with no fee for the return.
A note on coins that are not sovereigns
British gold coins from before 1816, guineas, half-guineas, third-guineas, and the older gold issues, also turn up in donations, usually in the same bags as Victorian sovereigns. These coins are 22-carat gold to the same general purity but to different weights, and they often carry significant numismatic premiums. The recognition is straightforward: if a small yellow coin looks British but does not show Saint George and the dragon, photograph it anyway and send it through the same WhatsApp route. GoldPaid will tell you whether it is gold and what to do next.
Common questions
How do I tell a sovereign from a foreign gold coin at a glance?
The reverse design. A modern sovereign shows Saint George on horseback slaying a dragon. Almost no other country uses that design. Some Victorian sovereigns show a heraldic shield on the reverse instead, which is also distinctive. If the coin shows an eagle, a maple leaf, a springbok or a portrait, it is not a sovereign.
Can a charity shop sell a sovereign over the counter instead?
It can, but the buyer setting the price on the shop floor has no way to verify purity, no way to detect a high-quality forgery, and no audit trail to support the trustees later. A postal route with XRF assay and a written offer gives the charity a recorded valuation and an evidenced sale price, which is the standard the Charity Commission expects on disposal of donated specialty items.
Is the postal route safe for a coin worth several hundred pounds?
Royal Mail Special Delivery is used with up to £2,500 cover, and higher cover is available on request before posting. The label is prepaid and the parcel is tracked end to end. A single sovereign sits well inside the standard cover; a larger group of coins is the case where the higher cover is worth arranging in advance.
What if the sovereign turns out to be a fake or a restrike?
XRF assay tells the difference between Royal Mint-struck gold and a later restrike or a forgery. The written report says exactly what the coin is. If the charity decides not to sell on the back of that information, GoldPaid returns the coin free of charge, insured, with no fee for the return.
Does a damaged sovereign still have value?
Yes. A sovereign that has been mounted in jewellery, soldered, polished, or holed for a chain still has its bullion gold content. It will not carry a numismatic premium, but the bullion floor is intact. The assay measures what is actually there, not what the coin would have been worth in mint condition.
How long does it take from sending the coin to the charity being paid?
Royal Mail Special Delivery is next working day. XRF assay and the written offer are usually completed within a working day of arrival. Where the offer is accepted before 3pm UK time, payment is by Faster Payments to the charity's registered bank account the same business day. From posting to bank, the typical end-to-end is two to three working days.
