Buy Physical Gold Bullion: A Complete Guide
Gold bullion refers to physical gold valued primarily for its precious metal content. Common forms include government-issued gold coins, privately refined gold bars, and fractional gold.
IDC Coin & Bullion offers gold bullion from recognized mints and refiners, along with historic and specialty gold products. Buyers can compare gold weight, purity, manufacturer, condition, and premium before making a purchase.
Unlike paper-based gold exposure, physical bullion involves owning the metal itself. Buyers should account for storage, insurance, transaction costs, and the difference between purchase and resale prices.

Government-issued gold bullion coins offer recognizable designs, standardized specifications, and different levels of purity. A coin's total weight and its actual fine gold content are not always the same.
| Gold Coin | Issuing Country | Standard 1 oz Issue Purity | Fine Gold Content |
|---|---|---|---|
| American Gold Eagle | United States | 22 karat / .9167 | 1 troy oz |
| American Gold Buffalo | United States | 24 karat / .9999 | 1 troy oz |
| Canadian Gold Maple Leaf | Canada | .9999 | 1 troy oz |
| British Gold Britannia | United Kingdom | .9999 (modern issues) | 1 troy oz |

Gold Bars vs. Gold Coins: Which Should You Buy?
| Consideration | Gold Bars | Gold Coins |
|---|---|---|
| Manufacturer | Private refiners and mints | Government issuing authorities |
| Common Sizes | Grams, troy ounces, larger bars | Fractional and one-ounce issues |
| Premium | Often competitive per ounce, depending on size | Varies by coin, mint, and demand |
| Collector Interest | Possible for vintage or unusual bars | Possible for scarce dates and special issues |
| Recognizability | Depends on refiner and product | Often strong for established bullion series |
Buyers focused on fine gold content may compare bars and bullion coins by total cost per ounce. Buyers interested in numismatics may also consider dates, mintmarks, grades, and designs.
Gold Bullion Weights: Grams, Troy Ounces & Fractional Sizes
Gold bullion is commonly quoted in troy ounces or grams. One troy ounce equals approximately 31.1035 grams. Fractional gold makes smaller individual purchases possible, although premiums per ounce may be higher.
| Fine Gold Weight | Approximate Grams | Typical Format |
|---|---|---|
| 1 gram | 1.0000 g | Small gold bars |
| 2.5 grams | 2.5000 g | Fractional gold bars |
| 5 grams | 5.0000 g | Gold bars |
| 10 grams | 10.0000 g | Gold bars |
| 1/10 troy oz | 3.1103 g | Fractional bullion coins |
| 1/4 troy oz | 7.7759 g | Fractional bullion coins |
| 1/2 troy oz | 15.5517 g | Fractional bullion coins |
| 1 troy oz | 31.1035 g | Coins and bars |
| 100 grams | 100.0000 g | Gold bars |
| 1 kilogram | 1,000.0000 g | Larger gold bars |
These figures represent fine gold weights, not necessarily total product weights. Alloyed coins and lower-fineness products can weigh more than their fine gold content.
24 Karat vs. 22 Karat Gold Bullion
Gold purity is described using karats or decimal fineness. 24 karat commonly refers to near-pure gold, while 22 karat gold contains approximately 91.67% gold by weight.
.9999 Fine Gold
Approximately 99.99% pure gold. Common in modern gold bars, Gold Buffalos, Maple Leafs, and other bullion products.
.999 Fine Gold
Approximately 99.9% pure gold. Also encountered in investment bullion and selected products.
22 Karat Gold
Approximately 91.67% gold, with additional alloy metals. Used in American Gold Eagles and South African Krugerrands.
Higher fineness does not automatically mean greater fine gold content or better value. Compare actual gold weight and total price.
How Are Gold Bullion Prices Determined?
The price of physical gold bullion is influenced by the market price of gold, the product's fine gold content, and the applicable dealer premium.
Gold Spot Price
The market reference price for gold, commonly quoted per troy ounce.
Dealer Premium
The amount above metal value associated with fabrication, distribution, demand, and transaction costs.
Numismatic Premium
Additional value that may reflect rarity, condition, mintmark, design, or collector demand.
Fine gold weight in troy ounces × current gold spot price per troy ounce = approximate underlying metal value. This excludes retail premiums, taxes, shipping, and resale spreads.
When comparing gold bullion, calculate the total cost per fine troy ounce. Remember that the price a dealer charges to sell gold can differ from its purchase offer for the same product.
How to Evaluate Gold Bullion Authenticity
Authenticating gold bullion involves examining the exact product specifications, minting characteristics, and metal composition.
Weight & Dimensions
Compare weight, diameter, thickness, and other measurements with published specifications.
Hallmarks & Packaging
Review manufacturer marks, stated fineness, serial numbers, and assay packaging where applicable.
Precious Metal Testing
Appropriate professional testing can help evaluate composition and detect suspicious products.
Counterfeit gold bars and coins exist. No single basic test guarantees authenticity. Higher-value or questionable items may require additional professional evaluation.
Historic Gold Coins & Collectible Bullion
Some gold products are valued for more than their precious metal content. Historic U.S. gold coins, older world gold, scarce dates, and professionally graded coins may carry numismatic premiums.
For collectible gold, factors such as authenticity, grade, rarity, and original surfaces can materially influence market value.
