Both bars and coins are bullion, meaning they’re valued mainly for the gold they contain. The right choice depends on your budget, how easily you want to be able to sell, and whether you want the product itself to be recognizable. Here is a plain comparison.
The short answer
For the lowest cost per gram, larger bars from a refiner you recognize usually win. For the easiest resale and instant recognition, popular government-minted coins are hard to beat. At very small sizes, such as 1 gram bars or fractional coins, both carry high premiums.
Side by side
| Gold bars | Gold coins | |
|---|---|---|
| Premium over spot | Usually lower per gram as bars get larger | Often higher, especially on fractional sizes |
| Sizes | From 1 gram to 1 kilogram and beyond | Mostly 1 oz, plus 1/2, 1/4 and 1/10 oz |
| Recognition | Strong for well-known refiners | Very strong for coins like the American Gold Eagle, Canadian Maple Leaf, Krugerrand and Britannia |
| Authenticity checks | Assay card and serial number | Standard design, weight and diameter, which makes checking easier for dealers |
| Legal tender | No | Yes, with a face value far below the gold value |
| Storage | Sealed card or capsule | Capsule, tube or flip |
| Best for | Lowest cost per gram at larger sizes | Easy resale and a recognizable product |
Coin purity is not always 99.99%
The Canadian Maple Leaf and current British Britannia are 99.99% pure. The American Gold Eagle and the South African Krugerrand are 22-karat (91.67% gold) and are alloyed with other metals to make them harder wearing. A 1-ounce Eagle or Krugerrand contains a full troy ounce of pure gold in a slightly heavier coin, so the pure gold content is what matters when comparing prices.
Bullion coins vs. collector coins
Bullion coins sell close to the value of their gold. Collector, or numismatic, coins sell for the rarity, condition and demand, which can mean paying far above gold value. If your goal is to own gold, buy bullion coins, and don’t pay a collector premium unless you know why you’re paying it.
Which should you choose?
- Choose bars if you want lower cost per gram and can buy larger sizes, or if you want a very small piece like a 1-gram bar for a gift.
- Choose coins if you value easy resale and instant recognition, and you don’t mind a slightly higher premium.
- Mix both if you want flexibility. Many people hold a few of each.
Whichever you choose, compare the total price per gram of gold. For a bar, that’s price divided by weight in grams. For a coin, use the actual gold content, not the coin’s gross weight. See the premium guide for the math.
Protecting small gold pieces
Fingerprints and scratches can lower the look and value of coins and small bars. Capsules and holders keep them clean. These are the ones we recommend.

Frequently asked questions
Are gold bars or gold coins better?
Neither is better in every case. Larger bars usually have lower premiums per gram, while popular coins are easiest to recognize and sell.
Which has a lower premium, bars or coins?
Generally bars, especially in larger sizes. At very small sizes the difference narrows and both are expensive per gram.
Are gold coins legal tender?
Yes, bullion coins carry a face value, but it’s far below the value of the gold, so nobody spends them.
Do I pay tax on gold bars and coins?
Tax treatment depends on where you live. In the United States bullion is generally treated as a collectible when sold at a gain. Speak to a tax professional.
