Investing in physical gold and silver is a popular method of wealth preservation, but it's essential to understand that there are various forms in which these precious metals are available. At Queensland Mint, we help our clients to understand the various options available for purchasing physical gold and silver, ensuring you can make an informed decision. In this article, we’ll explore the four main forms: cast bars, minted bars, coins, and granules—each with its own advantages and considerations.

1. Cast Bars

Definition:
Cast bars are produced by pouring molten gold or silver into a mold. Once the metal cools, the bar is removed and stamped with essential details like weight, purity, and the refiner's logo.

Appearance:
Cast bars typically have a rougher, more industrial appearance compared to minted bars. Their surfaces may be uneven, and they often feature visible pour lines or minor imperfections that give each bar a unique look.

Purity:
Gold cast bars typically come in .999 or .9999 fine gold, while silver cast bars are usually .999 pure. 

Pros:

  • Lower premiums: Cast bars are less labor-intensive to produce, so they often have lower premiums above the spot price compared to minted bars or coins.
  • Larger sizes: They are often available in larger sizes (e.g., 1 kg or 100 oz bars), making them ideal for bulk investments.
  • Industrial appeal: Many investors appreciate their rugged, raw look.

Cons:

  • No paper certificate: Some smaller cast bar sizes do not come with the paper assay certificate. This is not important to the value of the bar as the purity and weight is stamped directly onto the bar surface. 
  • Less attractive: They lack the aesthetic appeal of minted products, which may deter some collectors.

Who Buys Cast Bars?
Those prioritising value over aesthetics, who are seeking low premium or purchasing in bulk quantities. Cast Bars are the most popular form of bullion bar in Australia.

2. Minted Bars

Definition:
Minted bars undergo a lengthier process that gives them a smooth, polished finish. Starting as a precision cut blank,  they are struck under high pressure between dies to imprint the detailed design and logo on the bar.  Finished with a meticulous polishing process, most come sealed in protective packaging to preserve the finish and display the bar's assay information.

Appearance:
Minted bars are highly polished with a smooth, mirror-like surface. They often feature intricate designs and engravings, including the weight, purity, refiner’s stamp, and sometimes a serial number for added security. 

Purity:
Minted gold bars generally have .9999 purity, while silver minted bars typically offer .999 purity.

Pros:

  • Available in small denominations: Due to their precision manufacturing minted bars are available in much smaller sizes than cast
  • Attractive design: Their sleek, professional appearance makes them appealing to both investors and collectors.
  • Security features: Many minted bars come with security features like serial numbers, certificates, or tamper-evident packaging.

Cons:

  • Higher premiums: The production process for minted bars is more complex, leading to higher premiums over the spot price.

Who Buys Minted Bars?
Minted bars are popular with people who like to record serial numbers for insurance or auditing purposes and those who appreciate the aesthetic appeal of finely crafted bars.

3. Coins

Definition:
Coins are legal tender produced by national mints. They are often struck in limited quantities and in some circumstances may carry numismatic (collectible) value in addition to their bullion content.

Appearance:
Coins feature intricate designs, often depicting national symbols or historic figures. Their appearance is highly refined, with detailed engravings and a polished finish.

Purity:
Gold coins typically have .999 or .9999 purity, while silver coins are usually .999 fine.

Pros:

  • High liquidity: Coins are widely recognized and accepted, making them easier to sell quickly.
  • Government-backed: As legal tender, coins often come with the backing of a government, adding credibility.
  • Numismatic value: Some coins may appreciate in value due to rarity or collectible status.
  • Smaller units: Coins are available in smaller denominations, offering flexibility for investors.

Cons:

  • Higher premiums: Due to the additional costs of minting and their collectible value, coins often have higher premiums than bars.
  • Subject to wear: Coins are more prone to handling wear, which can impact their value over time.

Who Buys Coins?
Coins attract both investors and collectors. Investors favor them for their liquidity, while collectors appreciate their historical and artistic value.

4. Granules

Definition:
Granules, or bullion grains, are tiny pieces of gold or silver often used in manufacturing, particularly in the jewelry industry. They are sold by weight and purity, but not in a standardized form like bars or coins.

Appearance:
Granules are small, irregularly shaped pellets of gold or silver, often with a rough, industrial appearance. They are sold in bulk and typically come in sealed containers.

Purity:
Granules are generally .999 or .9999 fine for gold and .999 for silver.

Pros:

  • Versatility: Granules are easily melted and reshaped, making them ideal for manufacturers.
  • Lower premiums: Like cast bars, granules tend to have lower premiums since they don’t require the same minting process.
  • Sold by weight: Easy to buy in varying amounts based on weight and investment size.

Cons:

  • GST: Unlike bullion bars and coins, granules are subject to GST in Australia, making them less appealing to some individual buyers
  • Storage challenges: Due to their irregular shape, granules require more careful storage to avoid loss.

Who Buys Granules?
Granules are popular among manufacturers, particularly in the jewelry industry, due to their versatility. Investors looking for bulk purchases at lower premiums may also consider them, although they are less common for individual retail investors.

Key Learnings

  • Diverse Options: Gold and silver come in multiple forms, each suited to different investment goals and preferences.
  • Pricing and Aesthetics: Coins and minted bars offer uniqueness with  higher aesthetic appeal, while cast bars and granules provide lower premiums.
