With gold being used more as a means to hedge inflation, market volatilities, or currency risk, you’ll usually hear dealers or prospective buyers use what’s called ‘investment-grade gold.’ But what does it really mean, and how can you tell if what you bought is indeed investment-grade gold?
Here’s a straightforward, uncomplicated explanation to clarify what investment-grade gold entails, in addition to its importance in creating your precious metals portfolio.
What “Investment Grade” Really Means
Investment-grade in precious metals means gold coins meeting certain criteria for purity, authenticity, and value. These are not collectible items, precious jewelry, but bullion coins produced with a primary purpose in mind: asset preservation for investment purposes.
Gold needs to fulfill at least three major conditions to be considered investment-grade:
-
High Purity (Usually .999 or .9999)
Investment-grade gold has to be doubly pure. Most bullion coins and bars fall into either of these two levels:
- 99.99% pure gold (.9999) – For example, Gold Maple Leaf from Canada, PAMP Swiss Bars
- 99.9% pure gold (.999) – for example, American Gold Eagle (contains gold alloyed to 22k, yet it contains 1 full oz of pure gold)
- More purity leads to higher acceptability on an international level, better resale, and value.
-
Produced by a Recognized Mint or Refinery
Investment-grade gold needs to be produced by a reputable, world-recognized gold producer.
These include:
- Royal Canadian Mint
- PAMP Suisse
- Credit Suisse
- Royal Mint (UK)
- Austrian Mint
- Perth Mint
- Rand Refinery
- Johnson Matthey (Vintage)
- Asahi Refining
And gold from reputable firms means buyers understand it’s produced to industry standards, and there’s no problem reselling it anywhere in the world.
-
Comes With Verifiable Authenticity
Investment-grade gold usually contains features such as:
- Serial numbers
- Assay certificates or assay cards
- Mint Packaging
- Technologies for micro-engraving
- Sealable, tamper-proof packaging
These attributes enable buyers to be protected from fake products, while also guaranteeing their purity/weight for what they pay for.
Coins Vs. Bars: What Constitutes Investment Grade?
Bars, together with coins, could also be considered to be investment-grade–provided they fulfill the condition for purity and authenticity.
Coins That Qualify:
- Gold Maple Leaf
- Gold American Eagles
- Gold Britannia
- Gold Kangaroo
- Gold Philharmonic
- Gold Krugerrand
- Gold Buffalo
- Lunar Series Coins
These coins are minted by national mints, with assured weight and purity, and are most appropriate for investing, whether for novice or seasoned investors.
Bars That Qualify:
1g, 2.5g, 5g, 10g, 1 oz, 10 oz,
Bars from PAMP, Asahi, Italpreziosi, Perth Mint, Rand Refinery, Valcambi Suisse
Provided the bar is packaged, marked with its serial number, and from an accredited refinery, it qualifies for investment-grade gold.
What Doesn’t Count as Investment Grade?
It’s equally crucial to note what is not considered investment-grade:
- Gold jewelry, due to lower purity levels, with labor premiums
- Rare coins (value based on condition/rarity, not precious metal content)
- Gold-plated articles
- Unsealed or uncertified bars from unknown refiners
- Souvenirs or novelties in gold
These commodities could still retain some value, not, however, in the same predictable and world-known fashion as precious investment-grade bullion.
Why Investment Grade Gold Matters
