Gold bullion products are some of the purest forms of gold available in the world. When it comes to gold bullion, investors can choose from bullion coins, rounds, and bars. Each of these options is useful in its own ways and has its pros and cons.

What is gold bullion? 

Ever wonder why precious metals and soup share a name? Turns out, the word bullion comes from Old French, meaning “to boil.” Whether you’re refining metal or making stew, boiling happens… 

Gold bullion is “investment-grade” metal with a minimum of 99.5% purity. Unlike jewelry or most other metals, gold bullion is created for investors as well as for collectors. And because gold is a soft and easily malleable metal, it can take various forms, including coins, rounds, and bars. 

Gold bullion products are made in the following steps:

  1. Mining – Miner's separate gold-bearing ores from stone and naturally-occurring minerals under the earth’s surface.
  2. Extraction – Chemicals and heat are used to extract gold from sediment and other impurities. Extraction doesn’t result in pure gold but does separate gold and other metals from the mined ore.
  3. Refining – High pressure and heat drive off contaminants and refine gold as close to 100% purity as possible (currently, 0.99999 fine, or 1 part impurities for every 100,000 part gold).
  4. Assaying – The purified gold is “assayed” or tested for its purity to ensure it is up to the refiner’s standards.
  5. Pressing – Gold bullion is pressed into the desired shape: coins, rounds, or bars, with designs and/or mint markings as desired. 

Gold bullion can be refined into a variety of different forms, each of which has its benefits and drawbacks that investors should consider before buying. At the same time, it’s essential to understand that many precious metal options aren’t considered bullion, specifically numismatic coins, which are more generally collector’s items.

In essence: gold bullion’s value comes from its metal content alone. “Numismatic” coins may enjoy additional aftermarket value based on rarity, collectability, etc.

Gold bullion coins

Gold bullion coins are struck by government-backed mints, also known as sovereign mints. As such, these bullion products are backed by the full faith of the government in which they are minted and usually employ the highest security and anti-counterfeiting measures. “Full faith and credit” in this case is typically represented by stamping a face value on the coin, for example, the $5 a 1/4 oz American gold eagle is “officially” worth. Even though the coin’s metal is worth much more, as far as the issuing government is concerned, it’s worth $5.

Gold coins date back to 700 BCE in ancient China and 600 BCE in the west, but the first modern gold bullion coin is the South African Krugerrand, first minted in 1967. The Krugerrand became so popular in the gold market that it accounted for 90% of all the world’s gold coin sales by 1980. Unlike most other coins, the Krugerrand has no face value. Instead, in South Africa, it’s accepted as legal tender based on the spot price of gold.

Gold coins are legal tender in the nation they are struck and have a face value (with a few exceptions) at the time of striking. The value of the gold content fluctuates, but the face value remains the same. 

These coins are minted with intricate, often patriotic designs and have an intangible value that appeals to many.  Therefore, they’re valuable for their gold content and as collectibles, too. Some collectible gold bullion coins might be difficult to value as their worth can exceed their melt value (or the coin’s value if it was to be melted down to its metallic contents and sold as scrap). However, it’s safest to assume that a bullion coin, like any precious metal, is worth its melt value. That’s the most conservative assumption.

Bullion coins often contain small amounts of other metals, which increase the coin’s hardness and reduce scratching. 

Bullion coins most often come in sizes of 1 oz, 1/2 oz, 1/4 oz, and 1/10 oz. As for their market, bullion coins are highly liquid and available for purchase, making buying and selling coins extremely easy without compromising on price.


  • Top-quality minting and designs
  • Backed by a government and considered legal tender
  • Have a collectible and sentimental value


  • Often priced at a premium compared to the spot price of gold
  • Priced higher than other gold bullion products

Popular examples:

Gold bullion Rounds

A gold round has many similar characteristics to a gold coin, including its shape, size, and feel. But gold rounds differ in many important ways. Gold rounds are produced and struck by private mints, not government facilities. Therefore, they are not legal tender. 

Still, rounds maintain their status as investment-grade gold bullion for investors. And because rounds can have their own intricate designs and symbolism, they may be produced as limited-edition works of art that could become collectors’ items. Rounds need not be designed by a committee. The designs they incorporate could be anything from a simple refiner’s logo to an elaborate engraving of a popular cartoon character.

The market for bullion rounds is slightly less liquid than bullion coins, making rounds not as easily tradable as gold bullion coins. When purchasing gold rounds, always ensure you examine the mint logo, weight, and purity markings directly on the rounds. These will help ensure your purchase is authentic. 


  • Closer price to the spot price of gold than gold bullion coins
  • Can be more affordable to purchase than gold bullion coins
  • Larger variety of weights available, from 1/2 gram to 1 oz


  • Not backed by a government
  • Not considered legal tender
  • Less liquid and more likely to require an assay before being resold

  • Sunshine Minting gold rounds

Gold bullion bars

Gold bars were used as a form of currency dating back to the 7th century BC in Rome. Today, gold bars are strictly used as an investment vehicle and generally are viewed as having no collectible or sentimental value. These bars are often made by private mints, although some government mints produce bullion bars occasionally. 

Bars are produced in various weights, most often from 1 g to 10 oz, although some mints strike gold bars that weigh up to 400 oz. Gold bars of 1 oz are by far the most common.

Of all gold bullion products, large gold bars will be the lowest priced as they have the lowest price premium compared to the spot price of gold. 


  • Come in larger sizes than bullion coins and rounds
  • Easy to stack, store, and transport (though not significantly easier than coins or rounds)


  • Not considered legal tender
  • Value is derived solely from melt value

How to Choose Between Coins, Rounds, and Bars

  • Availability - Gold bullion coins like the American eagle, Canadian maple leaf, and South African Krugerrand have a highly liquid market and are readily tradable. On the flip side, the market for gold bars is usually less liquid.
  • Price premium - Gold coins have a higher premium over their melt value than bars and proofs. 
  • Risk of counterfeit - Bullion gold coins are secure investments and utilize the most advanced anti-counterfeiting technology. As for rounds and bars, anti-counterfeiting measures are determined by the producing mint. All three options often come packaged “in assay,” with information referencing the item's metal content, purity, and serial number. 
  • Storage - Gold bars can be the easiest to stack and store.
  • Future value - Gold bars and rounds will only retain their value related to the underlying price of gold. Gold bullion coins can increase or decrease in value based on their desire as collectibles but still mostly correlate to the spot price.
  • Dealer - More often than not, the best gold bullion products come from trustworthy dealers. So whether you are looking for coins, rounds, or bars, make sure to use a highly reputable gold bullion dealer for your transaction.
