In the US, gold bars usually cost less per ounce than gold coins, while bullion coins such as the American Gold Eagle and Buffalo are easier to recognize, easier to sell one at a time and, in the case of the Eagle, specifically allowed in an IRA. For federal tax purposes both are treated as collectibles, so the choice mostly comes down to premium, liquidity and how you plan to sell.
Bars vs coins at a glance
A bar is a piece of refined gold, usually .999 or .9999 fine, stamped with weight, purity and refiner. A bullion coin is struck by a government mint, has a legal face value far below its gold value and a fixed, published gold content.
| Factor | Gold bar | Gold bullion coin |
|---|---|---|
| Premium over spot | Lower, especially 10 oz and up | Higher per ounce |
| Federal tax on gains | Collectible (max 28% long-term) | Collectible (max 28% long-term) |
| Sizes | 1 g to 1 kg and larger | Mostly 1 oz and fractions |
| Recognition | Depends on refiner | Recognized by virtually all dealers |
| Selling part of a holding | Hard with one large bar | Easy, one coin at a time |
| IRA eligibility | If it meets fineness rules | Eagle named in law; others if fine enough |
Why bars usually carry lower premiums
A dealer’s price is the spot price plus a premium that covers fabrication, distribution and margin. Striking a coin with detailed designs and strict quality control costs more than pouring or minting a plain bar. The bigger the bar, the more ounces share the fixed production cost, so the premium per ounce falls.
Illustrative example (not current prices): if spot is $4,000 per ounce, a 10 oz bar at $40,800 has a premium of 2%, while a 1 oz Gold Eagle at $4,280 has a premium of 7%. Real premiums change with demand: in busy periods coin premiums can rise sharply. See current quotes on our US gold prices page.
Eagle, Buffalo or Maple Leaf?
- American Gold Eagle: 22 karat, alloyed with silver and copper for durability; the 1 oz coin weighs more than an ounce but contains exactly 1 troy ounce of gold. Usually the most widely traded US coin.
- American Gold Buffalo: .9999 fine (24 karat), 1 oz; its premium can differ slightly from the Eagle’s.
- Canadian Maple Leaf: .9999 fine, 1 oz, with security features added by the Royal Canadian Mint; its premium is sometimes lower than that of US coins.
All three contain one troy ounce of gold in their 1 oz size, so the comparison is mainly on premium and personal preference.
Tax and reporting
The IRS does not distinguish between bars and coins when it comes to gains: physical gold held more than one year is a collectible, taxed at a maximum federal rate of 28%; gains on gold held one year or less are taxed as ordinary income. State income tax may also apply. Reporting differs slightly: dealers file Form 1099-B when customers sell certain products in certain quantities, such as 1 kilo or more of .995+ gold bars, or 25 or more 1 oz Krugerrands or Maple Leafs, in one transaction. Gold Eagles are generally not on that list. A 1099-B does not change what you owe; gains are taxable either way.
Sales tax on purchases is a state matter and may treat bars and coins differently, so check your state’s rules.
Liquidity and flexibility
One 10 oz bar must be sold as a single item. Ten 1 oz coins can be sold one at a time, so you can raise only the cash you need and spread gains across tax years. Coins are also easier to sell in person at local coin shops, which may pay less for less familiar bar brands.
Authenticity
Both bars and coins are counterfeited. Government coins have strict published specifications, making weight and size checks simple. Bars from well-known refiners, ideally in sealed assay packaging with a serial number, are the easiest to resell at full value. Keep the packaging and invoice.
Common mistakes
- Buying proof or graded coins as bullion. Proofs and certified “rare” coins are priced well above their gold value; that extra may not be recovered when you sell to a bullion dealer.
- Comparing only the advertised price. Card surcharges, shipping, insurance and minimum orders can change which dealer is cheapest.
- Ignoring the buy-back price. A dealer’s bid for the same product tells you how much of the premium you might get back.
- Buying many 1 g bars. Tiny bars carry very high premiums per ounce; fractional coins are often a comparable alternative for small budgets.
- Throwing away assay cards. Bars in their original sealed packaging are easier to sell at full value.
Which suits which buyer
- Lowest cost per ounce: larger bars (10 oz, 1 kg).
- Small, regular purchases: 1/10 oz or 1 oz coins, accepting a higher premium.
- Selling in parts later: coins or several 1 oz bars.
- Gold IRA: Eagles, or bars and coins that meet IRS fineness standards, held by a custodian.

Bottom line
Bars generally win on price per ounce; coins win on recognition and flexibility. In the US, both are taxed as collectibles when sold at a gain, and the American Eagle has a specific place in IRA rules. Many holders combine a larger bar with a few coins.

Frequently asked questions
Are gold bars cheaper than gold coins?
Usually yes, per ounce of gold. Larger bars spread the production cost over more metal, so their premium over spot is lower than for coins.
Are gold bars and coins taxed differently in the US?
For federal income tax, both are collectibles. Long-term gains are taxed at a maximum rate of 28% and short-term gains as ordinary income.
Is the Gold Eagle or Gold Buffalo better?
Both contain one troy ounce of gold in the 1 oz size. The Eagle is 22 karat and the Buffalo is .9999 fine; prices usually differ only by a small premium.
Can I put gold bars in an IRA?
Bars that meet the IRS minimum fineness standard can be held in a self-directed IRA through a trustee or custodian. The American Gold Eagle is specifically allowed by law.
