1/20 oz American Eagle Gold Coin

The Smallest American Gold Eagle Denomination

The 1/20 oz American Gold Eagle contains 1.555 grams of pure gold in a 22 karat alloy (91.67% gold, 3% silver, 5.33% copper), with a total coin weight of approximately 1.70 grams. It carries a face value of $5 and is legal tender of the United States, its weight, content, and purity guaranteed by the US Government.

This is the rarest standard denomination in the American Eagle programme. The US Mint's Gold Eagle range starts at 1/10 oz ($5 face value) as its smallest standard bullion offering, and the 1/20 oz exists primarily as a special or limited release rather than an annual production staple. Most major government mints that produce 1/20 oz gold coins (the Royal Canadian Mint, Perth Mint, and Mexican Mint) do so as part of their regular fractional range, but the US Mint has historically focused its fractional production on the 1/10 oz, 1/4 oz, and 1/2 oz denominations.

The 22 karat alloy is the same composition used across all American Gold Eagle sizes, from the 1/20 oz through to the full 1 oz. Despite containing only 91.67% gold, the coin holds exactly 1/20 troy ounce of pure gold. The copper-silver alloy makes the coin harder and more resistant to surface marks than pure gold alternatives, a durability advantage that matters more at small sizes where coins are easily scratched during handling.

The obverse carries Augustus Saint-Gaudens' Lady Liberty design, originally created for the 1907 $20 Double Eagle and widely regarded as the finest coin design in American numismatic history. The reverse features the Type II eagle portrait by Jennie Norris (from 2021), replacing the original family of eagles design by Miley Busiek that had been used since 1986.

American Gold Eagle Denomination Family

The 22 karat alloy is distinctive: 91.67% gold combined with 3% silver and 5.33% copper. This composition was chosen for durability. The silver and copper alloy makes the coin harder and more resistant to scratching and denting than 24 karat alternatives, a consideration that matters most for the smallest denominations where handling damage is proportionally more visible. Despite the alloy, each denomination contains exactly its stated weight of pure gold. A 1/20 oz Eagle contains exactly 1/20 troy ounce of gold; the rest is alloy. This is why the total coin weight exceeds the stated gold weight.

Type II coins (2021 onward) include an anti-counterfeiting reed pattern on the edge, with a specific missing-reed position that varies by year, allowing authentication even without specialised equipment. Mint marks indicate the production facility: P for Philadelphia, W for West Point, S for San Francisco. The 2021 transition year is notable as the only year both Type I and Type II designs were produced, with Type I struck in the first half and Type II in the second half.

The obverse features Augustus Saint-Gaudens' Lady Liberty, originally designed for the 1907 $20 Double Eagle and considered one of the finest coin designs in American history. The reverse carries the Type II eagle portrait by Jennie Norris (from 2021), replacing the family of eagles by Miley Busiek that was used from 1986 through the first half of 2021.

1/20 oz American Gold Eagle Tax Treatment

The American Gold Eagle enjoys one of the most favourable tax positions of any gold coin, particularly in the United States, thanks to a special Congressional exemption from normal IRA purity requirements.

United States

• IRA: Eligible. American Gold Eagles are one of the very few 22 karat coins permitted in precious metals IRAs. The Gold Bullion Coin Act of 1985 provides a specific exemption from the normal IRS Section 408(m) requirement of 99.5% gold purity. This exemption does not extend to other 22 karat coins such as the Krugerrand or Sovereign.
• Capital gains: Outside an IRA, gains are taxed as collectibles at a maximum 28% federal rate, plus potential 3.8% Net Investment Income Tax. Within an IRA, gains are tax-deferred (Traditional) or tax-free (Roth).
• Reporting: Dealers must file IRS Form 1099-B for sales of 25 or more 1 oz Gold Eagles in a single transaction. Smaller denominations have no specific 1099-B trigger, though standard tax reporting obligations still apply.
• Sales tax: State-dependent. Approximately 35 states exempt bullion from sales tax.

United Kingdom

• VAT: 0%. Gold Eagles qualify as investment gold and are VAT-exempt.
• CGT: Not exempt. American Eagles are not UK legal tender. Gains are subject to CGT at the investor's marginal rate.

Canada

• GST/HST: The 91.67% purity is below Canada's 99.5% threshold for GST/HST-exempt precious metals. Gold Eagles may therefore attract GST/HST in Canada.
• RRSP: Not eligible (not issued by a Canadian mint).

Australia

• GST: The 91.67% purity is below Australia's 99.5% threshold for GST-exempt investment gold. Gold Eagles may attract 10% GST.

European Union

• VAT: American Gold Eagles appear on the EU's annual list of recognised investment gold coins and are VAT-exempt across all member states.

1/20 oz Gold Eagle vs Other Ultra-Fractional Gold

The 1/20 oz gold coin market is small. Only a handful of sovereign mints produce coins at this weight, and the American Eagle is an occasional rather than regular participant. The dominant products at 1/20 oz are the 1/20 oz Canadian Maple Leaf and the 1/20 oz Australian Kangaroo, both at 999.9 fine gold.

Against the Maple Leaf, the 1/20 oz Gold Eagle trades higher purity (999.9 vs 916.7) for alloy durability and the iconic Saint-Gaudens design. The Maple Leaf's four-nine purity makes it IRA-eligible under the standard rules, GST/HST-exempt in Canada, and GST-exempt in Australia, advantages the Eagle achieves in the US through its special Congressional exemption but cannot replicate in other jurisdictions. At 1/20 oz, the Maple Leaf is the more widely available and liquid coin.

Buyers considering the 1/20 oz Gold Eagle should compare it against the more standard 1/10 oz American Gold Eagle, which is the US Mint's standard smallest fractional denomination. The 1/10 oz carries the same $5 face value, the same IRA eligibility, and the same design, but with double the gold content. Premiums as a percentage of gold content are high at 1/20 oz (typically 15-25% over spot) and decrease at 1/10 oz (10-18%). Unless the absolute price point matters, the 1/10 oz is the more cost-efficient choice.

At current gold prices around $3,300 per troy ounce, a 1/20 oz coin contains approximately $165 of gold. This makes it a candidate for gifting, stocking stuffers, and budget-constrained entry into gold ownership. For accumulation purposes, moving up to 1/4 oz gold coins or larger substantially reduces the premium drag on returns.
