American Eagle
Also: Gold Eagle, Silver Eagle, US Eagle, AE
The American Eagle is the official bullion coin of the United States, minted since 1986 in gold, silver, platinum and palladium and among the most traded investment coins worldwide.
The American Eagle has been among the most significant bullion coins in the world since its introduction in 1986. Made possible by the Gold Eagle Coin Act of 1985 (Public Law 99-185) and the Liberty Coin Act, it is minted exclusively by the United States Mint - the oldest state coin mint in the USA. The coin is official legal tender of the United States, yet its material value far exceeds the stamped face value.
History and legal basis
The background to the introduction was the US Congress's intention to offer American investors a domestic alternative to the South African Krugerrand, which at the time was excluded from the market in many countries owing to apartheid sanctions. The gold originally came exclusively from American mines - a requirement that remains enshrined in law to this day. Gold and silver variants have been minted since 1986; platinum Eagles followed in 1997, and palladium Eagles were first issued in 2017.
Variants and denominations
The American Eagle appears in four metals, each with different denominations:
| Metal | Denominations (troy ounces) | Fineness | Face value (1 oz) |
|---|---|---|---|
| Gold | 1/10, 1/4, 1/2, 1 oz | 916.7 ‰ (22 carat) | 50 USD |
| Silver | 1 oz | 999 ‰ | 1 USD |
| Platinum | 1/10, 1/4, 1/2, 1 oz | 999.5 ‰ | 100 USD |
| Palladium | 1 oz | 999.5 ‰ | 25 USD |
The Gold Eagle is thus one of the few major investment coins with a 22-carat fineness (916.7 ‰). To nevertheless contain exactly one troy ounce of gold, the 1-oz coin weighs 33.931 g gross - the remaining roughly 2.83 g consist of a copper-silver alloy that gives the coin its characteristic, slightly reddish-golden colour and increased scratch resistance. The fine weight remains unchanged at 31.1035 g (= 1 troy ounce).
Calculating the fine weight
Fine weight (g) = gross weight (g) × fineness (‰) ÷ 1000
1-oz Gold Eagle: 33.931 g × 0.9167 = 31.10 g ≈ 1 troy ounce
You can calculate the current melt value of each coin size directly on the basis of the live gold price.
Motif and design
The obverse of the Gold Eagle shows the iconic Lady Liberty - an adaptation of Augustus Saint-Gaudens' famous design of the 1907 Double Eagle gold coin - complemented by a family of bald eagles on the reverse (design: Miley Busiek). The 1-oz silver coin bears Adolph A. Weinman's Walking Liberty on the obverse (known from the 1916-1947 Half Dollar) and a bald eagle with a heraldic shield on the reverse.
Since 2021 both coins have been reworked with modern security features (Type 2 design): the reverse now shows a more detailed eagle motif, and new micro-engravings and reeded edges make counterfeiting more difficult.
Authenticity and anti-counterfeiting
Because of its worldwide fame, the American Eagle is among the most frequently counterfeited investment coins. Reliable test methods:
- Weight and diameter - 1-oz Gold Eagle: 32.7 mm diameter, 2.87 mm thickness, 33.931 g. Deviations of more than 0.1 g are a warning sign. Use the Coin Weight Check.
- Magnet test - gold and silver are not magnetic; if the coin is attracted to a strong neodymium magnet, it is fake.
- Ping test - genuine Silver Eagles produce a bright, long-lasting tone.
- Sigma Metalytics / XRF - dealers use X-ray fluorescence or electromagnetic testing devices for a non-destructive analysis.
- Visual inspection - check micro-engravings and edge lettering under a loupe; note Type 2 features (from 2021).

Tax specifics (not tax advice)
In the United Kingdom the Gold Eagle - like all gold coins of fineness of at least 900‰ minted after 1800 - qualifies as VAT-exempt investment gold under HMRC rules. The Silver Eagle, by contrast, is subject to VAT: silver is not covered by the investment-gold exemption, so purchases from a VAT-registered dealer are generally standard-rated at 20 %. As foreign, non-UK coins, American Eagles are not legal tender in the UK, so gains on disposal are subject to Capital Gains Tax above the annual exempt amount (UK legal-tender coins from The Royal Mint, by contrast, are CGT-exempt). There is no German one-year speculation period. This is not tax or investment advice; please consult an accountant.
American Eagle vs. other world coins
| Coin | Country | Metal | Fineness | Special feature |
|---|---|---|---|---|
| American Eagle | USA | Au/Ag/Pt/Pd | 916.7 / 999 / 999.5 ‰ | 22-carat gold, legal tender |
| Krugerrand | South Africa | Au | 916.7 ‰ | Oldest modern bullion coin |
| Maple Leaf | Canada | Au/Ag/Pt/Pd | 999.9 ‰ | Highest fineness |
| Vienna Philharmonic | Austria | Au/Ag/Pt/Pd | 999.9 ‰ | Euro face value |
| American Buffalo | USA | Au | 999.9 ‰ | 24 carat, from 2006 |
The American Buffalo is the 24-carat complement from the same house - anyone preferring the highest fineness in a US gold coin reaches for the Buffalo. For premium development over time, the current gold price is the reference.
Premium and market liquidity
The American Eagle typically achieves a premium (agio) of 3-6 % over the spot gold price for the 1-oz variant; smaller denominations (1/10 oz) can be 20-30 % above the material value, since minting costs are spread over less material. The coin is recognised by almost all international precious-metal dealers and banks and is therefore extraordinarily liquid - a key advantage over regional or rarer coin programmes.
In brief
The American Eagle combines state guarantee, worldwide recognition and high liquidity in a single coin - making it one of the most straightforward entry points into physical precious metal. Anyone who values maximum fineness additionally chooses the American Buffalo or the Maple Leaf.
