How to Sell Coins in the UK: Getting a Fair Price

Before You Sell Anything, Do This First

A friend of mine – a retired schoolteacher from Derbyshire – inherited a biscuit tin full of coins from her late father. There were Roman denarii rattling around next to Victorian pennies, a handful of pre-decimal shillings, and what turned out to be a 1933 George V penny, one of the rarest coins in British numismatic history. She nearly sold the entire tin to a car boot stall holder for £15. Thankfully, she didn’t. That single 1933 penny, had it been genuine, could have fetched upwards of £72,000 at auction.

The moral is not that every biscuit tin is hiding a fortune. Most aren’t. The moral is that selling coins without doing your research first is one of the costliest mistakes a beginner can make. Whether you’ve inherited a collection, stumbled across something interesting at a market, or built up a modest accumulation over the years, understanding what you have – and knowing who to trust when you sell it – makes the difference between a fair price and a regrettable loss.

This guide is written specifically for people in the UK who are new to selling coins. It covers how to identify what you have, where to sell it, what to watch out for, and how to walk away feeling confident rather than cheated.

Know What You Have Before You Name a Price

It sounds obvious, but a surprising number of people try to sell coins they haven’t properly identified. The result is almost always the same: they either overestimate the value of common coins or, worse, underestimate genuinely scarce ones.

Start with the basics. For British coins, the date and the monarch’s portrait are your first two points of reference. Coins minted before 1947 contain actual silver – 50% silver between 1920 and 1946, and 92.5% (sterling silver) before that. Pre-1947 florins, half-crowns, shillings, and sixpences have an intrinsic metal value even if they’re worn flat and historically unremarkable. At the time of writing, spot silver prices mean a pre-1920 florin contains roughly £3-£4 worth of silver by weight alone. That’s your floor price.

For post-decimal and modern coins, condition and scarcity drive value rather than metal content. The Royal Mint releases mintage figures – the number of coins struck in a given year – and these are publicly available on their website at royalmint.com. A low mintage doesn’t automatically mean high value, but it’s a useful starting point. The Kew Gardens 50p, struck in 2009 with a mintage of just 210,000, regularly sells for £50-£150 in good condition. Meanwhile, a 2018 Peter Rabbit 50p with a mintage of 9.6 million is worth exactly 50p.

Two reference books are worth keeping on your shelf. The first is Coins of England and the United Kingdom, published annually by Spink & Son in London. It’s the definitive British coin catalogue and lists valuations by condition. The second is The Standard Catalogue of British Coins by Colin R. Bruce, which covers a broader historical range. Neither is cheap, but your local library may hold a copy, and older editions – though not current on prices – are still useful for identification.

Understanding Coin Grading

Professional coin dealers and auction houses assess coins using a standardised grading system. If you don’t understand grading, you’ll struggle to accurately assess value or compare prices. The main grades used in the UK are:

Poor (P): Barely identifiable. Heavily worn, details almost gone.
Fair (F): Design outline visible but very worn.
Fine (F) / Very Fine (VF): Moderate to light wear, most details clear.
Extremely Fine (EF): Only slight wear on the highest points. Most detail sharp.
Uncirculated (UNC): No wear whatsoever, as struck. May have contact marks from handling in the mint.
Brilliant Uncirculated (BU): As above but with full mint lustre and minimal marks.
Proof: Specially struck coins with mirrored fields and frosted devices, made for collectors rather than circulation.

Beginners often overgrade their coins. It’s a natural tendency – we see what we want to see. A coin you think is EF might be graded VF by a dealer, and that difference alone can halve the catalogue value. When in doubt, grade conservatively. You’ll build credibility with buyers and avoid awkward renegotiations.

Where to Sell Coins in the UK

There is no single best place to sell coins. The right venue depends on what you’re selling, how much time you have, and how much effort you’re willing to put in. Here’s an honest breakdown of your main options.

Coin Dealers

Established coin dealers are the quickest route to a sale, but they won’t pay retail prices – they can’t afford to. A dealer needs to cover their costs and make a margin when they resell, so expect offers of roughly 50-70% of catalogue value for common material, and potentially more for genuinely scarce pieces they know they can move quickly.

That said, reputable dealers are not trying to swindle you. They offer speed, certainty, and expertise. Spink & Son in London’s Southampton Row are among the most prestigious in the world. Baldwin’s of St James’s, also in London, is another long-established name. Outside the capital, look for members of the British Numismatic Trade Association (BNTA), whose directory is available at bnta.net. BNTA members are bound by a code of conduct, which provides some consumer protection.

If you live outside London – say, in Leeds, Bristol, Edinburgh, or Manchester – don’t assume you need to travel. Many BNTA dealers work by post and will assess coins from photographs before inviting you to send anything. Get multiple quotes before committing.

Auction Houses

For coins of significant value, auction is often the best route. Competition between bidders can push prices well above what a single dealer would offer. Spink, Baldwin’s, and Dix Noonan Webb all hold regular specialist coin auctions and accept consignments from private sellers. DNW, based in Mayfair, is particularly well regarded for British coins and has a strong international bidder base.

The trade-off is time and fees. Most auction houses charge sellers a commission – typically 15-20% of the hammer price – plus photography and catalogue listing costs. And it might be three to six months before your coins actually cross the block. For a coin that realises £500 at auction, the net return after fees might be £390-£420. Compare that to a dealer offer of £280 and the auction route still wins. But for a coin worth £30, the fees make auction impractical.

Always ask for a fee schedule in writing before consigning anything.

Online Marketplaces

eBay remains the largest online marketplace for coins in the UK and genuinely produces strong prices for the right material. The advantage is direct access to a large pool of collectors willing to pay close to retail. The disadvantage is that it requires effort: good photographs, accurate descriptions, postage and packaging, and dealing with buyers who occasionally aren’t entirely honest about their intentions.

For photography, a decent smartphone camera with a macro setting or close-up lens attachment is sufficient for most coins. Photograph both sides against a neutral grey or black background. Avoid flash photography – it bleaches out detail and creates glare. Natural diffused light, or a simple LED ring light, produces far better results.

Other platforms worth knowing: Catawiki holds online coin auctions with a European buyer base and has grown significantly in the UK market. MA-Shops is a fixed-price marketplace used heavily by professional dealers but open to private sellers. Facebook Marketplace can work for low-value bulk lots but offers little buyer or seller protection, so exercise caution.

Coin Fairs

Coin fairs are an underused resource for beginners. The two biggest recurring events in England are the London Coin Fair, held at the Holiday Inn Bloomsbury (usually monthly), and the Birmingham Coin Fair at the National Motorcycle Museum. Both attract dozens of professional dealers and offer a relaxed opportunity to get multiple opinions on your coins in a single afternoon.

Bring your coins along, talk to several dealers, and listen carefully to what they say about condition and demand. You don’t have to sell on the day. Many collectors visit fairs purely to research before selling elsewhere – and that’s entirely reasonable. Dealers expect it.

Specialist Coin Clubs

Local coin clubs can occasionally connect you with collectors interested in buying directly, cutting out the middleman entirely. The British Numismatic Society and the Royal Numismatic Society are London-based but have members nationwide. A quick search for “[your county] numismatic society” will often surface a local club. Direct private sales typically achieve better prices than selling to dealers, but they take longer and require a degree of trust between the parties.

Getting Multiple Valuations: A Practical Approach

Never accept the first offer you receive. This is not rudeness – it’s standard practice. Here is a sensible process for selling coins worth more than £50:

Photograph everything clearly before it leaves your possession. Keep a record of what you have.
Research the coins yourself using Spink’s
‘Catalogue of British Coins’ and completed auction records from Spink, DNW, or Baldwin’s. This gives you a realistic baseline rather than a wishful figure.
Get at least three valuations from a mix of sources: one dealer, one auction house estimate, and one from a collector or club contact if possible.
Factor in costs before comparing offers. Auction houses charge seller’s commission, typically between 10% and 20% of the hammer price, so a higher sale figure does not always mean more money in your pocket.
Take your time unless circumstances require otherwise. A coin that has waited in a collection for decades can wait another few weeks for the right buyer.

When comparing offers, ensure you are comparing like with like. A dealer’s immediate cash offer of £300 may be more practical than an auction estimate of £450 that carries a 15% seller’s commission, a photography fee, and a wait of three months before settlement. Write down the net figure for each option and assess from there. For coins of significant value, it is worth consulting a solicitor or independent specialist before proceeding, particularly if the collection has been inherited and ownership questions may arise.

Keep records of every communication, offer, and transaction. A simple spreadsheet noting the coin, its catalogue reference, any valuations received, and the final sale price will prove useful for tax purposes and for understanding which outlets worked best for your particular material. Capital gains tax obligations can apply where profits exceed the annual exempt amount, so it is worth checking current HMRC guidance if you are selling a large or valuable collection.

Conclusion

Selling coins fairly is largely a matter of preparation and patience. Understand what you have before approaching buyers, seek several independent opinions, and account for all costs before deciding which route suits you. The UK market for British coins is well established, with reputable auction houses, experienced dealers, and active collector communities all offering legitimate routes to a fair price. None of these routes guarantees the maximum possible return, but informed sellers consistently achieve better outcomes than those who accept the first figure put in front of them.
