Where to Sell Rare Coins UK 2026: The Complete Guide
The right place to sell a coin depends on its value, type and condition. A common 50p belongs on eBay UK; a Victorian sovereign at Noonans; a Charles I crown at Spink or Heritage. This guide covers every UK route, auction houses, BNTA dealers, eBay, coin fairs and private treaty, with realistic commissions, expected nets, tax treatment and the decision tree for choosing between them.

UK auction houses ranked
Noonans (formerly Dix Noonan Webb)
London auction house specialising in British coins, medals and banknotes. Noonans runs eight to ten coin auctions per year with strong online catalogues and international reach. Seller's commission is typically 15% with a 24% buyer's premium. The sweet spot is coins from £500 to £20,000; pricing is accessible and the catalogue presentation is competitive with the older houses. Photography fees may apply on smaller lots.
Baldwin's (A.H. Baldwin & Sons)
One of Britain's oldest coin specialists, founded 1872. Baldwin's runs themed auctions through the year, Argentum, the Pavlos S. Pavlou collection sales, Islamic coins specialist sales, and a regular private treaty business. Particularly strong on hammered British, milled silver and high-grade sovereigns. Commission structure is similar to Noonans.
Spink & Son
The grandee of British numismatics, founded 1666 with a royal warrant. Spink publishes the Standard Catalogue of British Coins (the trade reference) and runs premier auctions that combine coins, banknotes, medals and stamps. Best for high-value consignments at £2,000+ and especially for major collections being dispersed; their international reach is unmatched in the UK. Commission is negotiable on premium consignments.
Heritage Auctions
US-based but with significant UK-focused British coin sales. Heritage attracts US and Asian buyers that UK-only houses cannot match, especially relevant for Anglo-Indian sovereigns, Bombay-mint pieces and pre-decimal proofs. Buyer's premium is 20%, seller's commission is competitive. Worth considering for any coin where significant international interest is expected.
Stack's Bowers
The other major US house, with strong British coin presence in their world coin sales. Stack's Bowers is particularly competitive for hammered Anglo-Saxon, Tudor and Stuart material. UK shipping requires customs paperwork; for valuable consignments their UK office handles the logistics.
eBay UK: best for under-£500 pieces
For most modern collectable coins (Kew Gardens 50p, scarce £2 coins, common-date sovereigns) eBay UK delivers the best net return. Total fees work out to about 12.8% (final value fee tier-dependent, plus a payment processing fee absorbed into the same line since 2021). New sellers face a 14-day pay-out hold on first transactions. Practical tips:
- Auction format, 10-day run, ending Sunday 8–10 pm UK time. The peak bidding window for hobbyist-collectors who do not bid during work hours.
- Start at £0.99 with no reserve for items you expect to reach £20+. Attracts early bidders and drives competitive pressure; reserves suppress bidding.
- Photograph both sides on a neutral background with good lighting, ideally on a calibrated grey card. Include a weighing-scale photograph for higher-value pieces.
- UK-only postage avoids fraud risk and international payment headaches. Use Royal Mail Special Delivery Guaranteed for any sale over £100.
- Factual description. Avoid hyperbole ("super rare!!!"); experienced collectors see through it. State year, mint, denomination, mintage if known, weight and any visible defects.
- Slab high-value pieces. A PCGS or NGC slab adds liquidity, reduces buyer authentication risk and typically lifts realisations 15–35% over an equivalent raw coin.
BNTA dealers: the underrated middle ground
The British Numismatic Trade Association is the UK's professional body for coin dealers, with a published code of conduct and a member-search directory. BNTA-member dealers are the right route for coins in the £100–£1,000 bracket where eBay risk is real but auction commissions are disproportionate. Typical offer levels are 60–75% of retail, but the cash is immediate and the transaction is documented for provenance. Bring multiple coins; bulk consignment often secures better per-piece pricing.
Coin fairs and shows
- The London Coin Fair, held twice yearly (typically February and November) at the Holiday Inn Bloomsbury, Russell Square. The largest UK numismatic event; 50+ dealers attend. Good for cash sales in the £50–£5,000 bracket.
- The Midland Coin Fair, monthly at the National Motorcycle Museum, Solihull. Strong dealer turnout; particularly good for British hammered.
- The Birmingham Coin Fair, monthly at the Clarendon Suites; smaller but consistent.
- Regional and specialist shows, the BNTA publishes a calendar of smaller events at bnta.net.
At fairs, you pay no commission but dealers offer wholesale prices (60–75% of retail). The trade-off is immediate cash settlement and no consignment risk.
Bullion, numismatic and damaged: different routes
Three categories require different selling strategies:
- Bullion-grade coins (common-date sovereigns, Britannias, Krugerrands, gold bars), sell to a UK bullion dealer at spot minus 1–3%. BullionByPost, Chards, Atkinsons and the Royal Mint all run published-rate buyback programmes. For UK sovereigns and Britannias, the CGT exemption applies; see the tax section below.
- Numismatic coins (rare dates, high grades, proofs, condition rarities), consign to specialist auction houses (Spink, Baldwin's, Noonans, Heritage) or to BNTA dealers. The numismatic premium is invisible to bullion dealers, who price by weight; selling rare-date sovereigns to a bullion firm leaves a substantial portion of the value on the table.
- Damaged or cleaned coins, melt value only, unless the coin is rare enough that a damaged example still has collector interest. Cleaning or holing reduces auction realisations by 40–90%; a holed Charles I half-crown is still worth listing because the type itself is collectable, while a cleaned 1900 sovereign is bullion and nothing more.
How to prepare a coin for sale
- Authenticate. For coins over £100 send to PCGS, NGC or CGS UK. Cost £25–£50 per coin; uplift typically £30–£200 plus reduced consignment friction.
- Value-check. Use our UK coin value checker guide and cross-reference recent realised prices on Spink, Baldwin's, Noonans, Heritage and eBay UK sold listings. Three reference points give a realistic estimate.
- Do not clean the coin. Cleaning reduces value by 40–60% on most collectable coins. Original patina is prized, even on dirty-looking coins. The exception is a careful warm-water-and-soft-brush rinse to remove loose surface dirt; nothing more.
- Photograph thoroughly. Both sides on a neutral grey background, edge view if relevant, high-resolution close-ups of any defects. Include a slab certification label photograph for graded coins.
- Gather provenance. Original purchase invoice, prior auction lot slips, collector tickets, dealer receipts. Even informal notes ("bought from X dealer in 2010, previously in Y collection") materially add value for serious buyers.
- Get multiple appraisals. Single-dealer offers are usually low. Always get at least three quotes, ideally one auction estimate plus two BNTA-dealer offers.
UK tax treatment of coin sales
Tax note. UK-issued legal-tender coins minted from 1837 onwards are
exempt from Capital Gains Tax
under HMRC manual CG78308. This includes all sovereigns and half sovereigns from Victoria
onwards, all Britannias (1987 onwards), the Lunar series and modern circulating issues. Pre-1837
sovereigns and non-UK gold coins (Krugerrand, American Eagle, Maple Leaf) are chargeable assets
and any gain over the annual allowance is taxable. Investment-grade gold (.995+ fineness, plus
sovereigns explicitly listed in VAT Notice 701/21A)
is also exempt from VAT. Trading frequency may convert capital activity into income for tax
purposes; if you sell more than a few coins per year, take advice.
What NOT to do
- Do not melt silver coins. Post-1947 UK silver is only 50% silver and almost always worth more numismatically than as melt. Pre-1947 sterling is worth melting only if too damaged for collector interest.
- Do not accept cold-call offers. Scam calls claiming a coin is worth £500 and offering £100 cash are common; legitimate dealers do not cold-call private collectors. Walk away.
- Do not skip grading on coins above £200. A raw coin assessed by a buyer on arrival is always graded against you. Slab pre-emptively.
- Do not clean coins. Worth saying twice. Cleaning is the fastest way to destroy value.
- Do not use a single auction house quote. Estimates are indicative; the same coin can be valued differently by Spink, Noonans and Heritage. Get at least two written valuations before consigning.
- Do not sell under pressure. If a dealer or auction-house valuer creates urgency ("we have a buyer waiting today"), pause. Real bids stand for days.

Frequently asked questions
How much commission do UK coin auction houses charge?
The standard UK structure is a seller's commission of 10–20% of hammer plus a buyer's premium of 25–30% on top of hammer (often plus VAT on the premium). Spink, Baldwin's and Noonans all sit in this range. Photography fees (£5–£15 per lot), lotting fees and insurance during the consignment period may also apply. As a rule of thumb, on a coin that hammers at £1,000 the seller receives £800–£900 net and the buyer pays £1,250–£1,300 in total.
Should I use eBay or an auction house?
For coins under £100, eBay UK is usually better: lower total fees (around 12.8% final value fee plus payout deductions), broad buyer base and fast settlement. For coins above roughly £500, specialist auction houses (Spink, Baldwin's, Noonans) attract serious collectors who pay more for catalogued, authenticated pieces. The crossover sits at roughly £200–£300 hammer; below it eBay nets more, above it the auction house typically realises higher gross prices that more than cover the extra commission.
Do I need to authenticate a coin before selling?
For anything over roughly £100, yes. PCGS, NGC or CGS UK grading typically costs £25–£50 per coin and adds 15–35% to the achievable price by removing buyer authentication risk. For coins under £100 the fee usually exceeds the uplift. For consignment to a major auction (Spink, Baldwin's, Noonans) raw coins are accepted, but slabbed coins typically realise higher and avoid sellers' commission disputes over described condition.
When should I sell rare coins?
Coin auction realisations track gold and silver spot prices, broader auction-market sentiment and discretionary spending. Historically the strongest UK numismatic auctions are scheduled for late spring (April–May) and autumn (September–October) when international collectors are most active. December and August tend to be quieter. Major dated sales, Spink's September British coins auction and Baldwin's October Argentum, consistently realise stronger hammers than routine monthly sales. Time consignment deadlines around these dates.
Will a dealer pay more than auction?
Usually no, but with notable exceptions. Dealers typically offer 40–70% of expected auction realisation, which represents their carry cost (capital tied up in stock), authentication risk, and resale margin. Exceptions: a dealer who has a known buyer waiting for a specific coin may match or beat auction prices; BNTA-member dealers handling rare-date sovereigns and high-grade hammered coins can be competitive. Always get at least three quotes before consigning, and check recent auction realisations for comparable pieces.
Are coin sales subject to UK Capital Gains Tax?
British legal-tender coins minted from 1837 onwards are exempt from Capital Gains Tax under HMRC manual CG78308. This includes all sovereigns and half sovereigns from Victoria onwards, all Britannias, the Lunar series and modern circulating coinage. Pre-1837 sovereigns, foreign coins (Krugerrand, American Eagle, Maple Leaf) and gold bullion bars are not exempt and any gain over the annual allowance is chargeable. Investment-grade gold (.995 fineness or higher, plus listed sovereigns) is also VAT-free under VAT Notice 701/21A.
How do I sell a coin worth more than £10,000?
For a single coin above £10,000, do not accept the first offer. Get a written valuation from at least two specialist auction houses (Spink, Baldwin's, Noonans) and ideally one international house (Heritage Auctions or Stack's Bowers). For coins above £25,000, consider negotiating reduced seller's commission (down to 5–10%) and negotiate a published photograph in the printed catalogue. For coins above £100,000, private treaty via a top-tier dealer can sometimes net more than auction with no commission paid by the seller.
Should I clean coins before selling?
No, never. Cleaning a coin almost always reduces its value, sometimes by 40–60%, because abrasive or chemical cleaning leaves microscratches that any numismatic buyer or grader spots immediately. PCGS and NGC will refuse to assign a numerical grade to a cleaned coin, instead returning a "Details" designation that drops realisations sharply. Original patina is prized, even on dirty-looking coins. The only acceptable handling is a careful warm-water rinse to remove loose surface dirt; no soap, no rubbing, no dipping.
How do I package and ship coins for consignment?
For raw coins, use Lighthouse or Quickslab inert holders, individual numbered tickets, and acid-free envelopes for transport. For slabbed coins, the original PCGS or NGC plastic is sufficient; wrap in bubble film inside a rigid box. UK shipping should use Royal Mail Special Delivery Guaranteed (insured to £2,500 for the standard rate; up to £20,000 with high-value top-up). For consignments above £20,000, in-person delivery to the auction house or use of a specialist art-handler courier (Constantine or similar) is standard.
Are coin shows worth attending?
Yes, especially for sub-£5,000 coins where you want a cash offer without auction commission. The biggest UK events are the London Coin Fair at the Holiday Inn Bloomsbury (twice yearly, February and November), the Midland Coin Fair at the National Motorcycle Museum (monthly) and the Birmingham Coin Fair. Dealers offer wholesale prices (typically 60–75% of retail), but you avoid auction commission and the cash is immediate. Bring written provenance, slabs where available and realistic asking prices.
What records should I keep when selling?
Keep purchase invoices, any provenance documentation (collector tickets, auction lot slips, prior dealer invoices), grading certificates and consignment paperwork. Even where CGT does not apply (post-1837 UK legal tender), HMRC may ask to see records if your activity looks like trading rather than investing, trading profits are taxable as income regardless of the CGT exemption. Keep records for at least six years after sale.
Is selling a coin abroad worth it?
For high-value rarities with strong international markets, US-themed British issues (Bombay sovereigns, Edward VII Ottawa, key Victorian dates) and Roman or Greek coinage, yes. Heritage Auctions and Stack's Bowers regularly outperform UK houses for these niches. Costs to factor: seller's commission (similar to UK), international shipping and insurance, customs paperwork and US sales-tax administration on US-resident buyers. For coins under £5,000 the friction usually exceeds the uplift; consign domestically.
Do banks buy old coins in the UK?
No, UK high-street banks do not buy collectable coins. Banks will accept current legal-tender coins for deposit at face value (50p coins, £1, £2, etc.) but they will not pay collector premium for rare dates, low-mintage commemoratives or historical pieces. A 2009 Kew Gardens 50p deposited at a bank counter is credited as 50p, not its £150 secondary-market value. Banks will not exchange demonetised coins at all (round £1 since October 2017; pre-1997 large 50p since 1998; pre-decimal since 1971; sixpence since 1980). For demonetised coins the only options are coin dealers, eBay UK, or auction houses. Some banks may direct you to the Royal Mint exchange scheme, but that has been closed since 2018. Take collectable coins to a dealer or list them, never deposit them.
Will the Royal Mint buy back my coins?
No. The Royal Mint sells coins but does not buy them back. The official Royal Mint customer-facing channel is one-direction: they retail commemorative and bullion coins direct to consumers and through licensed dealers, but they do not operate a buy-back desk. The Royal Mint did run a one-off exchange scheme for the round £1 demonetisation in 2017-2018, which closed permanently. For modern bullion: the Royal Mint partner network of bullion dealers (Atkinsons Bullion, Baird & Co, BullionByPost) will buy bullion sovereigns and Britannias at spot less 1-3% spread. For numismatic and proof issues: secondary-market dealers and auction houses are the only path.
How long does selling a coin at auction take?
Plan for 3-6 months from consignment to settlement. UK numismatic auction houses (Spink, Baldwin's, Noonans) typically run 4-6 sales per year. Consignment deadline is usually 6-10 weeks before the sale date for cataloguing and photography. After hammer, settlement to the seller takes a further 4-8 weeks (typically 30-45 days post-sale per the auctioneer's standard terms). For urgent cash needs, eBay UK is faster (5-10 day listings, payment 14-21 days post-sale via PayPal hold) or BNTA-member dealer outright purchase (same-day cash, but lower price, expect 60-75% of auction-house net). Plan multiple sales in parallel rather than one consignment if you have a 30-coin lot and need multiple hammer dates.
