Explore Gold Bars by Size & Type
Gold bars are manufactured in a wide range of weights and styles. The right category depends on how much physical gold you want to purchase, the premium you're comfortable paying, and whether you prefer modern or collectible bullion.
Fractional Gold Bars
Shop small gold bars in weights such as 1 gram, 2.5 grams, 5 grams, 10 grams, and 20 grams. Fractional bullion offers smaller individual purchase sizes, although premiums per gram are often higher.

How to Choose the Right Gold Bar
The best gold bar for a particular buyer depends on more than its advertised weight. Consider the following factors when comparing products.
| Factor | What to Consider |
|---|---|
| Weight | Smaller bars offer smaller individual purchase amounts; larger bars consolidate more gold. |
| Purity | Many modern bars are .9999 fine, but verify the exact specification. |
| Manufacturer | Brand recognition, markings, design, and available documentation. |
| Packaging | Original assay cards, protective holders, or uncarded bullion. |
| Premium | The amount paid above the underlying fine gold value. |
| Resale | Authentication, dealer spreads, market demand, and divisibility. |
How Are Gold Bar Prices Determined?
The price of physical gold bullion generally reflects the current gold spot price, the product's fine gold content, and an additional retail premium.
The difference between a bar's retail price and its underlying fine gold value is its dollar premium.
Fractional gold bars often carry higher percentage premiums because fabrication and distribution costs are spread across smaller amounts of gold.
Larger modern gold bars may have lower premiums per fine ounce, but this is not guaranteed. Vintage bars may carry additional collectible premiums.
Always compare total acquisition costs, including applicable shipping, taxes, and payment-related charges.
Minted, Cast, Carded & Uncarded Gold Bars
Minted Gold Bars
Minted bars are manufactured with precisely formed surfaces and stamped or engraved designs. Many are sold in protective assay-card packaging.
Cast & Poured Gold Bars
Cast bars are formed using molten metal and molds. They may display distinctive textures, particularly in vintage poured bullion.
Carded Gold Bars
Carded bars are supplied in protective packaging that may identify the refiner, weight, fineness, and serial number.
Uncarded Gold Bars
Uncarded bars are sold without original sealed assay packaging. Genuine uncarded bullion retains its underlying gold value, although condition and packaging can influence premiums.
Packaging alone does not establish authenticity. Gold bullion should be evaluated using appropriate product specifications and authentication methods.
Gold Bars vs. Gold Coins
Gold bars and government-issued bullion coins both provide exposure to physical gold, but they differ in manufacturing, legal-tender status, and market premiums.
| Feature | Gold Bars | Gold Coins |
|---|---|---|
| Producer | Private refiners and mints | Government-authorized mints |
| Legal Tender | Generally no | Often yes |
| Common Weights | Grams and troy ounces | Fractional and full troy ounces |
| Purity | Often .9999 fine | Varies by issue |
| Collector Value | Possible for historic refiner bars | Possible for dates, grades, and rarities |
