A practical guide to selling inherited gold coins

If you have inherited gold coins, you are likely dealing with two problems at once: a personal loss, and a practical question you may not feel equipped to answer. This guide is written to help with the practical side. It covers the single most important distinction you need to understand, the tax position, where to sell, and the mistakes that cost people money.

Bullion value vs numismatic value — the key distinction

This is the most important thing to understand before you do anything else. Every gold coin has two possible sources of value, and they are very different.

Bullion value is the value of the gold itself — the weight of the coin multiplied by the current gold spot price. A modern Full Sovereign contains 7.32g of 22-carat gold. At a gold price of around £1,900 per troy ounce, that gold content is worth roughly £530. This is the floor price for that coin.

Numismatic value is the collector premium — the additional amount a coin is worth because of its age, rarity, condition, or historical significance. A Victorian Young Head Sovereign from the 1880s in good condition might sell for £400–£600 above its gold content. A rare date or mint mark could push that premium far higher.

The danger is obvious: if you sell a coin with significant numismatic value to a buyer who only pays bullion price, you lose that premium entirely. This happens routinely at "we buy gold" shops and pawnbrokers, who weigh coins and pay by gold content without assessing collector value. A specialist coin buyer will assess both.

A value comparison table

These are approximate values to give you a sense of the range. Actual values depend on condition, date, and current gold price. All bullion values assume a gold spot price of approximately £1,900 per troy ounce.

Coin Type	Gold Content	Bullion Value (approx)	Numismatic Premium
Full Sovereign (modern)	7.32g (22ct)	£530	Low — typically 5–10% above melt
Full Sovereign (Victoria Young Head)	7.32g (22ct)	£530	Moderate to high — £400–£600+ above melt depending on date and condition
Half Sovereign	3.66g (22ct)	£265	Low to moderate — older dates carry a premium
Krugerrand (1oz)	31.1g (22ct)	£1,900	Very low — these trade almost entirely on gold weight
Britannia (1oz)	31.1g (24ct)	£1,900	Low — slight premium for older or proof editions
Gold Guinea	8.35g (22ct)	£605	High — pre-1813 coins with significant historical premium, often £1,000+ above melt
Gold Noble	~7.7g (23ct)	£590	Very high — medieval coins, collector value often far exceeds gold content

If you have inherited a mixed collection, some coins may be worth close to their gold weight while others could be worth several times more. The only way to know is to have each coin assessed individually by someone with numismatic expertise.

How to identify what you have

You do not need to become an expert, but a few practical steps will help you understand your inheritance and protect you from undervaluation.

• Weigh each coin — use a digital kitchen scale accurate to 0.1g. A Full Sovereign should weigh 7.98g. A 1oz Krugerrand or Britannia should weigh 31.1g or 33.93g respectively. If the weight is significantly off, the coin may be a different denomination or not gold
• Look at the ruler's portrait — the monarch's head tells you the era. Victoria, Edward VII, George V, Elizabeth II — each narrows the date range immediately
• Check the date — usually on the reverse (tails) side. Certain dates are far rarer than others
• Note any mint marks — small letters on the coin (M for Melbourne, S for Sydney, P for Perth) indicate where it was struck. Some mint marks are scarce and carry significant premiums
• Look for denominations — Sovereign, Half Sovereign, Guinea, Crown. These tell you the coin type and expected gold content
• Do not use magnets — gold is not magnetic, but this test tells you very little. A non-magnetic coin could still be gold-plated or a different alloy

Capital Gains Tax on inherited gold coins

The tax position on inherited gold coins is more nuanced than most people expect. Here are the key points — but please note that this is general guidance, not financial advice. Always consult HMRC or a qualified accountant for advice specific to your circumstances.

CGT-exempt coins

UK Sovereigns and Britannias are exempt from Capital Gains Tax. Because they are classed as legal tender in the United Kingdom, any profit you make when selling them is not subject to CGT. This applies regardless of how much they have appreciated in value. This is a significant advantage and one reason Sovereigns and Britannias are so widely held.

Non-exempt coins

Krugerrands, foreign gold coins, and most other gold coins are not CGT-exempt. If you sell them at a profit above your base cost, that profit may be subject to Capital Gains Tax at your marginal rate (after your annual exemption). For a Krugerrand valuation, bear in mind that the taxable gain is calculated from the probate value, not the original purchase price.

How inheritance affects the base cost

When you inherit coins, your base cost for CGT purposes is the probate value — the value at the date of the deceased's death, not what they originally paid. If your relative bought Krugerrands in 1985 for £200 each and they were worth £1,500 at the date of death, your base cost is £1,500. You only pay CGT on any gain above £1,500 when you sell.

This means that if you sell shortly after inheriting, the gain (if any) is likely to be small and may fall within your annual CGT exemption.

Where to sell inherited gold coins

There are several routes, each with different strengths. The right choice depends on what you have and how much time you are willing to invest.

Specialist coin buyer

This is usually the best option for a mixed inherited collection. A specialist buyer has the numismatic expertise to identify and value each coin individually — including rare dates, mint marks, and condition grades that a generalist would miss. The process is straightforward: you send the coins (free insured postage), receive a written valuation, and accept or decline with no obligation. Payment is typically within 72 hours of acceptance. Selling a coin collection this way ensures nothing is undervalued.

Coin dealer

A reputable coin dealer — particularly one who is a member of the British Numismatic Trade Association (BNTA) — can provide a fair assessment. The advantage is face-to-face interaction and the ability to ask questions. The disadvantage is that you need to find a good dealer locally, and their offer will reflect their retail margin. Get offers from at least two dealers.

Auction

Auction suits genuinely rare or high-value coins where competitive bidding may achieve a premium. Spink, Dix Noonan Webb, and Baldwin's are the leading UK coin auction houses. The cost is 15–20% seller's commission plus a wait of 2–4 months. For most inherited collections that are primarily bullion coins with a handful of collectible pieces, this overhead is not justified.

Royal Mint buyback

The Royal Mint operates a buyback service for Britannia coins and some other Royal Mint products. This is a straightforward option if your inheritance consists primarily of modern Britannias. However, the Royal Mint pays bullion-based prices and will not offer numismatic premiums for older or rarer pieces.

Pawnbroker or "we buy gold" shop

This is almost always the worst option. These buyers pay by weight at a percentage of the gold spot price — typically 70–85%. They do not assess numismatic value. A coin worth £1,200 to a collector may be bought for £400 based on its gold weight alone. Only consider this route if you have confirmed that your coins have no collector premium and you need cash immediately.

Probate and inherited coins

If you are the executor of the estate, you will need a probate valuation for the coins. This is a formal assessment of their value at the date of death, which is used for Inheritance Tax purposes and also establishes your CGT base cost.

A probate valuation should be conducted by a qualified valuer — ideally a specialist coin valuer rather than a general probate valuer, as the latter may not recognise numismatic premiums. The valuation should list each coin individually with its assessed value. Keep this document carefully: you will need it if you sell the coins and need to calculate any CGT liability.

If the total estate value is below the Inheritance Tax threshold, you may still want a proper valuation to establish your CGT base cost — particularly if the coins include non-exempt types like Krugerrands that you may sell later at a higher price.

Mistakes to avoid

Selling to a "we buy gold" shop

As explained above, these buyers pay by gold weight and ignore collector value. If even one coin in your collection has significant numismatic premium, you could lose hundreds or thousands of pounds. Always get a specialist assessment first.

Cleaning the coins

This deserves its own section because it is the most common and most irreversible mistake.

Splitting sets or groups

If your relative collected coins in sets — for example, a complete date run of Sovereigns, or a proof set in its original case — keep them together. A complete set is worth more than the individual coins sold separately. Even if the coins are not a formal set, a coherent collection from one collector often has a narrative that adds value.

Not getting multiple valuations

Never accept the first offer without comparison. Get at least two independent valuations, ideally from specialist coin buyers rather than generalists. The difference between a well-informed buyer and an uninformed buyer can be substantial — particularly for older coins where date, mint mark, and condition interact to affect value in ways that are not obvious.

Rushing the decision

Gold coins are not perishable. They have held value for centuries and will continue to do so. Unless you have urgent financial need, take time to understand what you have before selling. A sovereign valuation or specialist assessment costs nothing and ensures you make an informed decision.
