How to Use This Reference
This table covers the most widely traded government-minted bullion coins in gold and silver. Every specification is sourced from the issuing mint. The melt value column updates automatically based on the current spot price and each coin's pure metal content.
When comparing coins, pay attention to purity and gross weight. A .9999 fine coin like the Canadian Maple Leaf contains the same amount of pure gold as a .9167 fine American Eagle, but the Eagle is heavier overall because of its copper-silver alloy. Both contain exactly 1 troy ounce of gold.
Use our premium calculator to determine what you are paying above melt value, or check the premium tracker for current dealer pricing.
Frequently Asked Questions
What is the difference between gross weight and pure metal content?
Gross weight is the total weight of the coin including all metals. Pure metal content is the weight of just the gold or silver. For example, a 1 oz American Gold Eagle has a gross weight of 33.93 grams but contains exactly 1 troy ounce (31.1035 g) of pure gold. The remaining weight is copper and silver alloy added for durability.
Are all bullion coins IRA eligible?
No. The IRS requires a minimum purity of .995 for gold and .999 for silver to qualify for a self-directed precious metals IRA. The American Gold Eagle is an exception, allowed despite its .9167 purity due to specific legislation. Coins like the Krugerrand (.9167 purity) do not qualify.
Why do fractional coins carry higher premiums than 1 oz coins?
Fractional coins cost nearly the same to design, die-strike, and package as full-ounce coins, but contain less metal. The fixed production costs are spread over a smaller amount of gold, which raises the per-ounce premium. A 1/10 oz coin can carry a premium two to three times higher (as a percentage) than the same coin in a 1 oz size.
What does face value mean on a bullion coin?
Face value is the legal tender denomination stamped on the coin by the issuing government. It is symbolic and far below the actual metal value. For example, the American Gold Eagle carries a $50 face value but contains over $2,000 worth of gold. Face value gives the coin legal tender status, which can offer certain tax and import advantages.
How is melt value calculated?
Melt value equals the pure metal content (in troy ounces) multiplied by the current spot price per troy ounce. It represents the intrinsic metal value of the coin, ignoring any numismatic premium or dealer markup. Use the melt value as a baseline when evaluating any bullion purchase.
