Gold and silver coins sit at a fascinating crossroads. Some are prized for their history, design and rarity; others are valued mainly for the metal they contain. Many collectors enjoy both: a few modern bullion coins alongside older pieces with a story to tell. Whatever draws you in, buying well means understanding what you are paying for, how coins are graded, how tax works and how to avoid fakes.

This guide covers the essentials for collectors in Europe, the UK and beyond.

Two kinds of coins: bullion and numismatic

Bullion coins

Bullion coins are modern coins struck by national mints in large numbers, mainly for their precious metal content. Their price follows the market price of gold or silver, plus a premium that covers minting, distribution and the dealer’s margin. Well-known examples include the Krugerrand, the Britannia, the Maple Leaf, the Philharmonic and the American Eagle.

Numismatic coins

Numismatic coins are valued for more than their metal: age, historical significance, rarity, condition and demand among collectors. Their price can be far above the metal value, and it depends heavily on grade and authenticity. This is where expertise matters most and where the most interesting collecting happens.

Many coins sit somewhere in between. A common older gold coin in average condition may sell close to its metal value, while the same type in exceptional condition can attract strong collector interest.

Understanding the price you pay

  • Spot price: the current market price of the metal, usually quoted per troy ounce.
  • Premium: what you pay above the metal value. It tends to be higher for smaller coins, special finishes and limited editions.
  • Buy-back price: what a dealer will pay you if you sell. The gap between buying and selling prices is a real cost of ownership.
  • Fees: at auction, a buyer’s premium applies. Bonhams’ US schedule, for example, lists 20% on the hammer price for coins and medals (accessed 25 October 2026). Shipping, insurance and storage add further costs.

Compare the full price per gram of fine metal across several dealers before you buy, and always check the dealer’s current buy-back price as well.

Tax: why gold and silver are treated differently

In the European Union, gold coins can fall under a special VAT scheme. Under Article 344 of the EU VAT Directive (2006/112/EC), a gold coin qualifies for this scheme, which the Directive calls “investment gold”, if it has a purity of at least 900 thousandths, was minted after 1800, is or was legal tender in its country of origin, and is normally sold at a price not exceeding the open market value of its gold content by more than 80%. The European Commission publishes a list each year of gold coins that meet these criteria; the Directive also covers gold bars and wafers of at least 995 thousandths purity. Supplies of qualifying gold are exempt from VAT.

Silver does not benefit from this scheme. Silver coins are generally subject to VAT in the EU, although some dealers sell certain collectors’ coins under a margin scheme, which can affect the price. VAT rates and the way schemes are applied differ by country, and rules outside the EU (including in the UK) are different again. If tax matters for your decision, check the rules in your country or ask a tax adviser.

Grading: how condition is described

Condition is everything for numismatic coins. The two best-known third-party grading services, PCGS and NGC, authenticate coins, assign a grade and seal them in tamper-evident plastic holders often called “slabs”. Both use the Sheldon scale from 1 to 70, where 1 is barely identifiable, 60 to 70 covers uncirculated (“Mint State”) coins, and 70 is a coin without visible post-production imperfections under magnification. Coins with problems such as cleaning or damage may receive a “Details” grade instead of a numeric grade.

European dealers and auction houses often use traditional descriptive grades as well, such as Fine, Very Fine, Extremely Fine and Uncirculated, or their equivalents in other languages. These are less standardised, so look carefully at the photos rather than relying on the label.

Things that reduce desirability

  • Cleaning: never clean a coin. Cleaning leaves hairline scratches and an unnatural shine that experienced collectors spot immediately.
  • Handling marks: hold coins by the edges, ideally with cotton gloves.
  • Mounting: coins that have been set in jewellery usually show traces of solder or a loop.

Authenticity and fakes

Counterfeit coins and bars are a real problem, especially online. Protect yourself with a few habits:

  • Buy from established dealers, mints and auction houses with a physical address, clear terms and a return policy. Many reputable dealers are members of professional numismatic associations.
  • Prefer coins certified by a recognised grading service for higher-value numismatic purchases, and check the certification number on the grader’s website. Fake slabs exist too.
  • Know the specifications: weight, diameter and thickness for common bullion coins are published by the mints. A precision scale and calipers will catch many fakes.
  • Be wary of prices below spot. Nobody sells real gold for less than its metal value.
  • Avoid unverified sellers on general marketplaces and social media, and never pay by untraceable methods.

Storing and insuring your coins

Keep coins in their original capsules or slabs, or in inert holders made for coins. Avoid PVC flips for long-term storage, as they can damage the surface over time. Store your collection somewhere dry and secure, and check whether your home insurance covers coins and precious metals or whether you need specific cover. Some collectors use a bank safe deposit box or professional vault storage. Keep an inventory with photos, purchase invoices and certificate numbers.

Building a collection with purpose

  • Choose a focus: a country, a period, a series such as sovereigns or ducats, or a theme like ships or royalty.
  • Learn before you buy: standard catalogues and auction archives show what you can expect to pay for a type and grade.
  • Buy the best condition you can afford within your focus, rather than many lesser examples.
  • Keep good records of every purchase.

Coins sometimes appear in the general sales of the major auction houses, as well as in specialist numismatic auctions. Our Auction Calendar lists major upcoming sales.

Frequently asked questions

Do I pay VAT on gold coins in the EU?

Gold coins that meet the criteria in Article 344 of the EU VAT Directive are exempt from VAT. Coins that don’t meet them, such as many silver coins or gold coins sold at a high premium, may be subject to VAT.

What does “MS70” mean?

It is the top grade on the Sheldon scale used by PCGS and NGC: a Mint State coin without visible post-production imperfections under magnification.

Should I clean old coins to make them look better?

No. Cleaning damages the surface and makes a coin less desirable to collectors.

Are gold coins a safe way to protect my money?

We don’t give financial advice. The price of gold and silver can fall as well as rise, and buying and selling involves costs. Collect coins because you enjoy them, and seek independent advice for financial decisions.
