Selling Gold Coins in the UK: Sovereigns and Britannias

A bullion coin is the easiest thing in Britain to turn back into money, and most of what decides your number is settled before you speak to anybody. Here is what a dealer actually checks, which of your coins to part with first, and the one thing you should never do to a coin you intend to sell.

Five things worth knowing before you sell a coin

• A full Sovereign is not a quarter ounce of gold. It weighs 7.98 g gross at 916.7 fineness, which works out at roughly 7.31 g of fine gold. It takes about four and a quarter of them to match one 1oz Britannia.
• Recognition is worth more than purity. A 916.7 Sovereign sells faster in Britain than a 999.9 coin nobody at the counter has handled before.
• Condition matters less than people fear, and cleaning matters far more than they expect. Honest wear is priced in. Polish is not.
• Sell the right coin first. If you need a set amount rather than a clean exit, the order you sell in changes what you are left holding.
• Silver is a different job. Same coin idea, far more weight and volume for the same value, and that shows up in packing, postage and cover.

One Britannia, or four and a quarter Sovereigns

Start with the comparison that decides most sales, because it is the one people get wrong. The Royal Mint publishes a weight and size table for the Sovereign range: a full Sovereign is 22.05 mm across and weighs 7.98 g at 916.7 fineness. That fineness is the catch. Multiply it out and the coin holds about 7.31 g of fine gold, not the 7.98 g on the scale.

A 1oz gold Britannia is 999.9 fine and contains a full troy ounce, which is 31.10 g. Divide one by the other and you need about four and a quarter Sovereigns to match a single Britannia for metal.

That matters in both directions. If you are selling to raise a particular sum, Sovereigns give you a finer instrument: you can part with four and keep the rest, where one Britannia is all or nothing. If you are selling the lot, the Britannia is the simpler parcel to count, check and pay for. Neither is better. They suit different exits, and knowing which you are doing is most of the decision. Our comparison of the gold Britannia and the gold Sovereign goes through the rest of the differences.

What a dealer actually checks, and in what order

There is no mystery to the process, and knowing the order removes most of the anxiety from it. A buyer works through four questions, and a recognised bullion coin answers the first two by itself.

Identification comes first. Type, mint and denomination, which for a Britannia or a Sovereign is a glance. Then weight, against the published specification for that exact coin rather than a general figure, because a coin that is light is either worn, wrong, or not what it claims. Then verification: dimensions, a magnet, and density if there is any doubt at all. Genuine coins pass in seconds. Finally the lot is counted and priced, and that is where quantity, condition and packaging move the number.

If you want to run the arithmetic yourself before you ask anybody for a figure, what is my gold worth takes it step by step, including how to get a reliable weight at home.

What sells quickly in Britain, and what does not

Liquidity is not the same thing as value. Some coins are worth a great deal and still take weeks to sell, because the pool of buyers is small. The table below is about speed and certainty, not about which coin was the better purchase.

The line running through that table is verification. Anything a buyer can identify and check in under a minute prices tightly. Anything that has to be assessed piece by piece prices cautiously, because caution is the only protection a buyer has against being wrong.

The portrait changes. The coin does not.

People often assume an older Sovereign must be worth more because it looks older. Sold on bullion terms it is not. Every full Sovereign in the modern series carries the same 7.98 g at the same 916.7 fineness, whichever monarch is on the front, and a dealer buying for metal will price a Victoria and a Charles III alike.

Where the portrait does earn something is scarcity. Certain dates and mints are genuinely uncommon, and a collector will pay for those specifically. That is a different sale to a different buyer, and it is worth ten minutes of checking before you send a box of mixed dates off to be weighed. If a coin turns out to be ordinary, you have lost nothing. If it turns out not to be, you have saved the difference.

Do not clean them

This is the single most expensive mistake in the whole process, and it is made with the best of intentions. People want to present their coins well.

Polishing takes a thin layer off the surface permanently and leaves fine hairline marks that an experienced buyer sees immediately. It removes any collector premium the coin had and it cannot restore the original lustre or the toning it replaced. A dirty coin is a coin. A polished coin is a coin with a problem. Send them exactly as they are, in whatever tube, capsule or case they came in, and let the buyer decide what they are looking at.

The same applies to packaging. Original tubes, capsules, boxes and certificates are part of the value on anything with a collector element, and they cannot be recreated. Throwing them away to save space in the parcel is a real cost.

Silver sells by the box, not by the coin

A silver Britannia holds the same one troy ounce as its gold namesake, in a coin 38.61 mm across rather than 32.69 mm. Because silver is worth a small fraction of gold per ounce, a silver holding of any given value is far heavier and far bulkier than the gold equivalent.

That is not a reason to avoid selling silver. It is a reason to plan the sale differently. Expect counting to take longer, expect the parcel to be heavier than you guessed, and check the cover on whatever service you use before you post rather than after. Our guide to moving metal safely sets out the realistic postal and insurance ceilings, and gold against silver covers why the two metals behave so differently in the first place.

Silver also has its own checklist at the point of sale, and it is not the gold one with the numbers changed. Surface marks behave differently, packaging counts for more than most sellers expect, and the difference between a silver Britannia and an American Silver Eagle is not only the design. Selling silver in the UK covers all three properly, including the one thing sellers do to a spotted coin that genuinely costs them money.

Which coin should you sell first?

If you are selling everything, the order does not matter. If you need a particular sum and want to keep the rest, it does, and this is where most people give the question no thought at all.

There is an argument for doing exactly the opposite, and it is worth stating fairly. If you believe the collector market for a particular piece is thin and getting thinner, selling it while there is still a buyer is the rational move. The default above assumes you are raising cash rather than exiting a position you have lost confidence in. Only you know which of those you are doing.

Six mistakes that cost sellers money

Working backwards from the headline gold price

The price you see quoted is a wholesale figure for large unallocated bars. Nobody pays it for a coin in a jiffy bag. Working out what your holding is genuinely worth, and why the offer sits below the headline, is covered properly in what dealers actually pay.

Selling the easiest item rather than the right one

The coin nearest the top of the box is not necessarily the one to part with. Five minutes deciding the order is worth more than an hour comparing buyers.

Breaking up a set

A complete set is worth more than the sum of its coins to the person who wants the set. Once it is split, that buyer is gone.

Cleaning

Covered above, and worth repeating because it is irreversible.

Posting before agreeing what happens if you decline

Ask, in writing, what the return arrangement is and who pays for it if you do not accept the offer. A buyer who cannot answer that plainly is telling you something.

Selling in a hurry when you did not have to

Urgency is the most expensive thing you can bring to a sale, and it is the one part of the transaction entirely within your control.

How selling to Yard Mint works

Our sell to Yard Mint page now publishes indicative buying rates for gold and silver, calculated automatically from our own vaulted product prices using physical-processing buy multipliers. Most UK dealers quote only on request, so a published rate is unusual, and it exists so that you can do the multiplication before you speak to anybody rather than after.

Treat it as an anchor rather than a settlement. It is derived from investment-grade vaulted pricing, and the final number for your specific items depends on what they are, what condition they are in, how many there are and what verification shows. The page is explicit about that and so are we.

The process itself is three steps. You tell us what you have and we reply with pricing and next steps. Once you accept, you follow our instructions to send the items. After verification, payment goes to your bank account. Goldbacks follow their own process, set out on our Goldback services page, and selling Goldbacks in the UK covers the realities of that market honestly.

Who should not sell to us

We would rather lose ten minutes of your time than waste an afternoon of it.

• If you hold jewellery, scrap or broken pieces. We buy bullion only. A jeweller, a pawnbroker or a scrap refiner is the right buyer, and a valuation from a recognised trade body member is a sensible first step.
• If you need cash in your hand today. Our process runs by post and verification, and that takes time a walk-in counter does not.
• If you hold a single low-value coin. Postage and insured cover eat into a small sale. Wait until you have enough to make the parcel worth sending, or sell locally.
• If you hold a genuinely scarce collector piece. A specialist auction or a numismatic dealer may find a buyer we cannot, and you should let them try first.
• If you are only selling because the price moved this week. That is the worst reason there is, and it is not one we are going to encourage.

If you are buying rather than selling, buying gold bars in the UK works through the other side of the same arithmetic.

Frequently asked questions

Where can I sell gold coins in the UK?

Bullion dealers, coin dealers, auction houses and pawnbrokers all buy gold coins, and each suits a different situation. A bullion dealer is usually the fastest and most predictable for recognised coins such as Sovereigns and Britannias. A coin dealer or auction house is the better route for a scarce date or a complete set. Whoever you approach, ask what the return arrangement is before you send anything.

How much will I get for a gold Sovereign?

It depends on the gold price on the day and on the buyer, so no fixed figure is honest. What you can work out in advance is the metal: a full Sovereign weighs 7.98 g at 916.7 fineness, which is about 7.31 g of fine gold. Multiply that by the current price per gram of fine gold and you have a ceiling. The offer will sit below it, because the buyer has to cover verification, handling and their own risk.

Should I sell Sovereigns or Britannias first?

If you need a specific sum rather than a clean exit, Sovereigns give you finer control, because each one is roughly a quarter of the gold in a 1oz Britannia. If you are selling everything, it makes little difference. Either way, sell the coins you could most easily buy back before the ones you could not.

Do I need the original box or tube to sell a coin?

Not for plain bullion, where the coin is priced on its metal and its condition. For proofs, commemoratives and anything sold as a set, the packaging and certificate are part of the value and cannot be replaced. If you still have them, send them.

Should I clean my coins before selling them?

No. Cleaning removes surface metal permanently, leaves marks a buyer can see, and destroys any collector premium. Circulation wear is expected and priced in. Send coins exactly as they are.

Can I sell silver coins to Yard Mint?

Yes. We buy silver bullion coins and bars alongside gold. Silver is bulkier and heavier for a given value, so allow more time for counting and check the cover on your postal service before sending. Our guide to selling silver in the UK covers condition, packaging and the Britannia against the American Eagle in detail.

Does Yard Mint buy gold jewellery or scrap?

No. We buy bullion only, which means coins and bars, plus Goldbacks through our own Goldback process. If you hold jewellery, scrap or broken pieces, a jeweller, a pawnbroker or a scrap refiner is the right buyer for them.

How long does it take to get paid?

Payment is sent to your bank account after your items arrive and are verified. We confirm the expected timing for your sale when we reply to your quote request, because it depends on what you are sending and how it is sent.
