Gold Coin Buyers Guide: Why, How And When To Buy Coins In 2025

Gold has been one of the most popular investments over the past 5 years. That’s not surprising with returns exceeding 60% over that period and beating most other asset classes. But experienced investors will know the real reason for the marked interest in buying gold coins and bullion bars is down to gold’s role as a safe haven in unstable times.

Given the financial crisis that UK residents, in particular, have been put through, gold represents a safe investment. Unstable currencies, flailing financial institutions, high inflation and geopolitical uncertainty are exactly the kind of scenario that will drive up interest in gold investing. With a limited gold bullion supply, it’s only expected that this growing demand will continue pushing up gold prices.

But if you have not invested in gold coins or gold bars before, you may not be sure about where to start. The range and price of coins can be overwhelming as you try to sort your Double Eagle from your American Buffalo, or your Gold Panda from your Maple Leaf. To optimise your gold investment returns, you’ll need to understand the various weights, purities and types of gold coin. You’ll need to learn when to buy coins rather than bars, where to purchase, store and sell them, how to time the market and how to shield your profits from the taxman.

. This precious metal has a lot to offer when it comes to tax benefits, steady value, and peace of mind, and it can add stability to your investment portfolio.

With that in mind, here are some of the most important things that you should know about when, what, how and why to invest in gold bullion coins. Step-by-step.

Let’s start by asking the question: why would investors want to add gold or silver to their investment portfolio? One of the most compelling reasons is that there is a finite supply of gold. As such, increasing demand means that while gold prices may waver, they always increase over the medium to long term.

Gold coins, like Britannias, Krugerrands and Sovereigns are well-known worldwide, so you don’t need to worry about selling your gold overseas.

Most every day people will have noticed that banks are now making it difficult to spend your own money. Try making an electronic payment to a new payee, and it’s likely they’ll block the transaction. Owning gold coins gives you autonomy and control over your own wealth.

There are also tax benefits to buying gold coins. For example, in the United Kingdom, you will not have to pay Capital Gains Tax on any legal tender gold coins that have been made by the Royal Mint. This means that when you sell Royal Mint-manufactured gold coins, you will be making a tax-free profit.

Your typical gold bullion coin is also easy to buy and simple to sell, which makes it a very appealing investment to add to your portfolio. One of their key benefits is the divisibility they offer. For example, a £5,000 investment would buy around 12 Gold Sovereign coins, meaning you’d have 12 pieces of gold, rather than one gold bar. This provides the flexibility to sell small parts of your portfolio when you like, whether it be to lock in some profit or simply cash some in for a holiday.

It’s also important to note that the price of gold tends to do well when other market investments take a downturn. For this reason alone, it can be argued that it’s always important to own some gold to protect against falling markets – expected or otherwise. By owning some gold coins alongside your other assets such as property, stocks, bonds or crypto, you’re more protected when the economy declines. Gold coins are also a fantastic hedge against inflation, and come with a far lower barrier to entry than gold bars.

Physical gold coins tend to appreciate in price when there is turbulence and turmoil in the world’s economy. Traditionally, gold is a non-volatile investment when considered over a longer horizon, so gold coins are a great diversifier within your portfolio.

This will feel particularly relevant at the moment to anyone living in the United Kingdom, but gold coin prices tend to go up sharply when uncertainty enters the world. With the current cost of living crisis, UK residents are seeing inflation rise while the threat of recession continues to loom large.

As inflation rises, the value of your money goes down. This is where buying gold coins can be an important store of wealth. It is one of the best hedges against inflation you can own, and performs significantly better than raw cash at holding its value.

By simply leaving savings in the bank, you’re losing purchasing power on a daily basis. Your Pound may be able to buy a loaf of bread today, but it may only afford ⅔ of that same loaf in a year’s time. Diversifying into gold during inflationary periods can protect your money’s value.

There are many types of gold coins to buy, each serving a different purpose for investors. First it’s best to outline what types of gold coins are in existence and how they differ:

• Gold Bullion Coins: Bullion coins made of precious metals such as gold and silver, though there are also platinum and palladium bullion coins. These are usually made via a country’s mint, but there are cases where private companies will also mint them. The term ‘bullion’ can be a mis-used and confusing one. While it’s commonly used to describe gold bars, it also defines the manufacturing process of gold coins. A bullion coin is one which has been minted cost-effectively and aimed at the investment market. This contrasts with proof coins, which are cast twice, increasing production cost, and are more suitable for collectors.
• Numismatic Coins: These coins have something called a numismatic value, which can make the coin more valuable than the gold it contains. For example, if the coins are historically relevant or have an unusual error on them. These coins are often very rare, and exist in a market different to gold bullion coins, and should be bought for a different purpose. These very high premium numismatic coins are not to be confused with semi-numismatic coins, which can make a great investment choice. A common example of these would be pre-owned Sovereign coins dating from Elizabeth II back to Victorian versions. They’re not old enough to be classed as numismatic, but can create values over and above the gold price due to scarcity and collectability.
• Legal Tender Gold Coins: There are gold bullion coins which can also be used as legal tender within a certain country. These include the Gold Britannias and Sovereigns in the UK, the Maple Leaf in Canada and American Eagles in the USA. In the UK, Britannias and Sovereigns are free from capital gains tax due to their legal tender status.

There are many choices when it comes to gold coin sizes and weights. It’s important to understand that these weights refer to the ‘pure gold weight’ and not the total coin weight. For example, a 1 ounce Krugerrand will contain exactly 1oz of pure gold, but weigh slightly more due to additional alloys.

1oz coins

Many of the world’s best known coins are produced in a 1oz weight. The South African Krugerrand was the first coin minted in this convenient size, back in 1967. With its weight matching that of the commonly quoted gold price (one ounce), the coin’s value was simple to track. This shrewd marketing led to the first mass-appeal gold bullion coin. Many of the world’s leading mints have since followed suit including the Royal Mint’s very own 1oz Gold Britannia. You can find more information about some of the best 1oz gold coin investments in 2023, in our detailed guide.

Half, Quarter and Tenth oz coins

Retail interest in smaller versions of these coins has led to fractional varieties of the leading world coins. Minted in smaller quantities, the smaller coins offer a more affordable option for smaller investors, appeal to collectors wishing to own all sizes available and high divisibility for those seeking to own small gold tokens for possible bartering if paper currency fails.

This added flexibility comes at a cost, with premiums higher on the smaller coins due to increased relative production cost.

Sovereign coins

These deserve to be mentioned as they’re so popular for investors worldwide and they’re one of the best-known gold coins. Sovereign production pre-dates the introduction of convenient ounce based measures so their weight seems more complex in comparison.

A full Sovereign contains 0.2354 ounces of pure gold, or 7.32g. In simple terms it’s just slightly smaller than quarter ounce gold coins. This enhances their popularity as they are affordable, tradeable and better value than ¼oz versions of larger coins.

The Sovereign is also produced in Half and Quarter versions to provide further divisibility.

There are many different types of gold coins on the market, the most popular in the UK being the Britannia and the Sovereign. Both of these coins come with excellent tax benefits for UK residents, and are a great option for small and large investors alike.

Once you’re sure on the route to take, there are a number of ways you can buy gold coins for your collection.

• A registered and approved gold dealer
• A jeweller
• An online private seller (using a marketplace such as eBay)

Each of these options can have their own strengths and weaknesses.

Some jewellers will often hold small quantities of gold coins, sometimes with the intention of selling, as they would a ring or necklace

Gold collectors, and owners, can sometimes turn to marketplaces such as eBay to sell their gold to the mass market.

If you were to use physical gold, like thousands of others have over the past few years, you get all of the benefits of buying from an accredited gold dealer and the process is simple:

As they are smaller than gold bars, coins can be stored more easily in your home. You can store gold coins in specialist tubes, a vault or safety deposit box at home or in a specialised insured facility.

Technically, due to the fact that gold coins don’t corrode when exposed to the environment, you can store them anywhere you like. The main thing to watch out for is that you don’t scrape or scratch them (as you could lose precious micro-ounces of gold). Gold coins should be enjoyed so don’t be afraid to handle them.

If you do choose to keep your gold coins at home, ensure they are secure and insured against theft.

This question is a little more complicated than it may first appear. On the surface, it would seem to be a purely aesthetic decision. Do you want the commemorative element that comes with fine gold coins or that satisfaction of owning a bigger, more impressive lump of gold?

Gold coins are often made to mark a historical event or to create beautiful collector’s items.

Gold coins are also smaller than most gold bars, which means that they are easier to store and offer you flexibility to sell part of your holding. The tax benefits mentioned above means that you can buy and sell gold coins with a better profit margin.

It’s also worth noting that gold coins can be bought in smaller denominations, so if you just want to make a smaller investment, they may be a better option for you initially.

There are also several compelling reasons why you may want to buy gold bars instead of gold coins. For example they can be cheaper per Troy ounce for investors, especially when buying at scale. Interestingly, small gold bars of 5 and 10 grams in weight are far more expensive per gram than small gold coins like Sovereigns (7.32g). So the assumption that gold bars are the more cost effective option is only accurate when buying larger sizes.

Every investor will wonder if now is a good time to buy or a good time to sell. When it comes to gold, one of the best things about it as an investment is that the risk to you is always going to be fairly low. The upfront prices may be high when you buy coins, for example, but you know that they are likely to retain their value and give you a good return for your money.

If you have money that you want to convert into something reliable, investing in gold coins makes a lot of sense.
