One Ounce Gold Bullion Bar : Pre-Owned (Best Value)

100g Gold Bar
(VAT Exempt)
One of our most popular pre-owned bullion bar types is the best value one ounce gold bar, sold at a small margin over the live gold price. Each gold bullion bar offered in this product is pre-owned and chosen at random from our current stock, allowing us to offer them at very low premiums. Our team of experts has tested each one ounce gold bar in detail on site using a specialist XRF machine to determine the metal composition, ensuring you get a genuine gold bar. This means the bar you receive could be issued loose without the plastic assay card, but we guarantee each bar will contain 31.10 grams of pure gold. The refinery stamp, alongside the weight and fineness, will be visible on each investment bar. The pre-owned 1oz gold bars we issue will be roughly 40.00 mm x 25.00 mm in size, although the exact specifications for each refinery can vary. A comparable item in size would be a new-style Royal Mail stamp (with the barcode). We only sell what we physically have in our vaults, so if this listing is showing as out of stock, we encourage you to sign up to our useful 'Track Product' option so you can be notified when the 1 ounce gold bars are available again. UK residents can benefit from free delivery when they purchase these investment gold bars from the Britannia Coin Company, which are sold VAT-free.

Pre-owned one ounce gold bars available at low premiums from The Britannia Coin Company of Royal Wootton Bassett.

Buy 1oz Gold Bars

One ounce gold bars can be a great investment for those looking to diversify their portfolio or add to their precious metal stack. Each bar contains exactly one troy ounce (31.10 grams) of pure gold, struck in at least 0.999 fineness (24 carat).

The dimensions of a typical gold 1 ounce bar will vary depending on the refinery, with an approximate length and width being around 40.00 mm x 25.00 mm. This is comparable to a new style Royal Mail letter stamp (with a barcode). They're usually no bigger than 2mm thick.

Nearly all gold ingots come in square and rectangular shapes, which makes the storage of them comparatively simple. They fit neatly inside a home safe or a safe deposit box.

Best Value Gold Bars

The investment 1oz gold bars we offer are usually offered loose, without any outer packaging. The vast majority of gold 1oz bars are issued in a 'minted' format, with cast versions only issued by a few refineries. The Britannia Coin Company doesn't differentiate between the two types as they both contain exactly the same amount of gold.

'The refinery of your gold bar can vary as it's allocated on a random basis from the stock we currently have. This allows us to offer them at very low premiums.'

Our team of experts use the latest XRF technology on site to check the composition of each bar in our inventory, ensuring you get a genuine, correct-weight gold bar every time. You can read more about our XRF machine on our sister website, Gold Traders UK.

Investing in Gold Bars

Purchasing physical 1oz gold bars is an easy way to acquire the precious metal and there's a very liquid market in them worldwide. The one ounce bar is an incredibly popular weight of bar amongst investors and is universally recognised. The main advantages of investing in pre-owned 1oz gold bars are:

  • Cost - 1oz gold bars are sold at a low premium above the live spot price, and are typically cheaper in terms of price per ounce than gold coins
  • Authenticity - all of our one ounce gold bars are stamped with the refiner's logo
  • Security - all of our bars come from reputable refiners, and we test each bar we receive to make sure it's genuine
  • Popularity - genuine gold 1 oz bars are easily recognised by reputable bullion dealers worldwide, making them easy to sell on
  • Store of Value - gold is regarded as an inflation hedge, which has protected wealth over time
  • VAT Free - all gold bars sold by the Britannia Coin Company qualify as investment gold, which means they are exempt from VAT

1oz Gold Bars or 1oz Gold Coins?

For investment purposes, it's wise to purchase gold at the lowest possible margin over the live spot price, irrespective of design, shape or metal fineness. In percentage premium terms, 1oz gold bars tend to be slightly more expensive than 1oz gold coins, although this occasionally is not the case. 

Take the South African 1oz gold Krugerrand for example. Often they're available at a lower premium than 1oz bars, but a deal-breaker for some investors is they're 22 carat (0.917 fine). Whilst they nevertheless contain 1 troy ounce of gold, some investors prefer 24 carat (0.999 fine) bullion. When our pre-owned 0.999 fine 1oz gold bars are compared to 0.999 fine gold 1oz coins, they're often available at a cheaper margin. 

'If you're looking for gold bullion at low premiums, our pre-owned 1oz gold bars are a great option to look at. But consider if gold 1oz coins are a more suitable option for you.'

Other considerations to think of are capital gains tax implications and the ability to liquidate part of your gold portfolio. You can read more about this in-depth in our Buying Gold Bars vs Gold Coins article.

If these considerations are of no concern to you, then the competitive margin offered on these pre-owned 1oz gold bars can make them a very attractive investment option. We have acquired a significant amount of expertise from the years we have been in business, so we feel we can provide useful information for investing in gold for the interested layperson. However, please note that this doesn't constitute financial advice.

Pre-Owned Gold Bars

Pre-owned gold bars are an excellent choice if you're looking for the cheapest premiums on gold bullion. 

'We acquire these bars from the secondary market, which allows us to offer them at a really low margin.'

They're sold purely for their precious metal content, irrespective of brand. Some bars may have very slight marks on them, which is perfectly normal on second-hand bullion bars; we guarantee that all these bars will contain exactly one troy ounce of pure gold.

Gold Refiners

All the pre-owned gold bars we offer for sale come from highly regarded and reputable precious metal refineries. This is a list of examples, which is non-exhaustive:

  • Umicore
  • Heraeus
  • Baird & Co
  • Metalor
  • PAMP Suisse
  • Royal Mint Refinery

Authentic investment gold bullion bars should be stamped with the weight, purity and refinery. Certain bars have a unique serial number as well, but some brands choose to omit this. The bullion value of the bar is not affected in this case.

Tax Free Gold Bars

One of the most compelling reasons to purchase investment gold bars is the fact that the precious metal has VAT-free status. Investment gold has been exempt from VAT in the UK and the EU since January 2000.

All gold bullion bars sold by The Britannia Coin Company meet this definition, meaning HMRC will treat them as VAT-exempt, therefore allowing you to buy gold tax free. 


We are always proud to show off our previous customers experiences with you and what they thought of our purchasing through with Britannia Coins.
