20g Gold Bullion Bar : Pre-Owned (Best Value)

Buy a 20g Gold Bullion Bar : Pre-Owned (Best Value)

(VAT Exempt)
Our best value 20 gram gold bars are an excellent way to acquire gold bullion at a small margin over the live spot price. They're perfect for investors looking to add to their precious metals portfolio or for those looking to invest in gold for the first time. One of the top reasons to choose pre-owned twenty gram gold bars from the secondary market is the fact that they're reasonably affordable for all budgets and represent a cost-effective way of investing in the precious metal. The Britannia Coin Company possesses a high-tech XRF machine on-site, which our highly experienced team uses to ascertain the authenticity of every gold bullion bar we receive. That way, any 20g gold bar you purchase from us is guaranteed genuine. During this exhaustive testing process, outer plastic packaging may have been removed, which means the bar you receive could be issued loose. Each investment gold bar features the refinery, weight and fineness stamped onto the front of it. In terms of specifications, each bar will vary depending on the refinery issued, with a rough size guide being 31.00 mm by 18.00 mm. Should these gold 20g bars be unavailable, you can sign up to our practical 'Track Product' facility so notifications can be sent directly to you when they're back in stock again. All our gold bullion bars qualify as investment gold for tax purposes, which means these 20g gold bars are VAT-free. Included in our price is free shipping to UK addresses.

Pre-owned twenty gram best value gold bars for sale from the Britannia Coin Company of Royal Wootton Bassett.

Gold Bar Brands

The pre-owned gold bars we offer for sale come from internationally-recognised refineries. A sample list of some the brands we offer in this 'our choice' product are:

  • Metalor
  • Baird & Co
  • Royal Mint Refinery
  • Umicore
  • PAMP Suisse
  • Valcambi SA

All legitimate investment gold bullion bars, including these pre-owned 20 gram gold bars, should be stamped with the weight, purity and refinery. They may also have a unique serial number, but some refineries do not include serial numbers on their smaller gold bars. This omission does not affect the bullion value of them.

Buy 20 Gram Gold Bars

20 gram gold bars can be a great investment for those looking to diversify their portfolio or add to their collection. Each bar contains roughly 0.6430 troy ounces of pure gold, struck in at least 0.999 fineness (24 carat).

The dimensions of a typical 20g gold bar will vary depending on the brand, with an approximate length and width being 31.00 mm x 18.00 mm respectively. A comparable item to this would be an old-style Royal Main stamp, which is very slightly larger. Each bar is usually around two millimetres thick.

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

Cheap Gold Bars

These investment gold bars may be either loose or in their original outer packaging. 20g gold bars universally come in a 'minted' format, with cast 20g gold bars effectively unheard of. 

'The brand and style 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.'

Each pre-owned gold bar we have has been thoroughly tested by our in-house team of experts. As a result of this authenticity process, we may have to remove any outer packaging to properly examine the bar. We possess the latest XRF technology on site to check the composition of each bar in our stock, ensuring you get a genuine, correct-weight gold bar every time. More can be read about our XRF machine on our sister website, Gold Traders.

Pre-Owned Gold Bars

Second-hand gold bars are a great choice if you're looking for the lowest premiums on gold bullion. 

'We obtain these bars from the secondary market, which allows us to offer them at very low premiums.'

They're sold purely for their precious metal content, irrespective of refinery. Some bars may have some slight blemishes, which is normal on second-hand bars, but we guarantee that all these bars will contain exactly 20 grams of pure gold and be suitable for bullion investment.

Is It Worth Investing in Gold Bars?

Gold bars can be a great addition to any investment portfolio! One of the most popular ways to invest in gold bullion to purchase 20g gold bars -  there's in demand around the world with a very liquid market in them. We've outlined some reasons why you should consider buying them:

  • VAT Free - all investment gold bars sold by the Britannia Coin Company are VAT-free
  • Internationally Recognised - Any reputable bullion dealer worldwide will recognise a genuine gold 20g bar, making it easy to liquidate in the future
  • Store of Value - gold is regarded as an inflation hedge, which has protected wealth over time
  • Low Premiums - 20g gold bars are sold at a competitive premium above the live spot price
  • Authenticity - all of our gold twenty gram bars are stamped with the brand, weight and fineness 
  • Security - all of our bars come from reputable refiners, and we thoroughly test each bar we get to make sure it's genuine

Are Small Gold Bars A Good Investment?

Smaller-sized gold bars such as 1 gram, 2 gram, 5 gram and 10 grams tend to be bought as novelty items or for gifts, with more economical investment options being on larger bars. This threshold is usually met with 20g gold bars, which are the smallest size which could be bought at reasonable margins over the spot price. Investors find these bars popular because buying several smaller-weight bars gives the option to sell on part of a stack at a later time, which wouldn't be possible if one larger bar was bought.

'If you're looking for bullion gold bars at the cheapest margin over the spot price, then our pre-owned 20 gram bars represent an excellent opportunity.'

 There are other factors to consider, for example capital gains tax implications. You can read more about this in-depth in our Buying Gold Bars vs Gold Coins article.

VAT Free Gold

Investment gold is exempt from VAT in the United Kingdom as a result of an EU directive commencing in January 2000. This law is still currently in force in the UK. 

All gold bullion bars sold by The Britannia Coin Company meet the definition, which means they are sold without any VAT. The sale of physical silver, platinum and palladium products are still liable for VAT at the standard rate, which makes physical gold an attractive investment option.
