1991 American Gold Eagle

Every 1991 Gold Eagle version

Eight 1991 versions exist. The four bullion coins have no mint mark and a bright finish; the four proofs have mirror fields, frosted devices and a mint mark. Proofs were sold in capsules with presentation boxes and certificates, while bullion coins went out in bulk. Because the 1991 half ounce bullion coin is so sought after, check that a loose half ounce isn't a proof that lost its box. The two are valued very differently. Measure and weigh any 1991 half ounce as well, since a coin this sought after is a natural target for counterfeiters.

Quick answers

How much gold is in a 1991 Gold Eagle?

Each coin contains its stated weight of pure gold: 1/10 troy ounce in the $5 coin, 1/4 troy ounce in the $10 coin, 1/2 troy ounce in the $25 coin and one troy ounce in the $50 coin. The alloy is 91.67% gold, 3% silver, 5.33% copper.

How many 1991 Gold Eagles were made?

243,100 one ounce bullion coins plus 224,709 collector versions (proof, burnished and special finishes).

Is the 1991 Gold Eagle worth more than its gold?

The bullion coin trades close to its metal value plus a dealer premium. The scarcer collector versions of 1991 are a different story; see the table above.

Is the Gold Eagle legal tender?

Yes. Each size carries a face value ($5, $10, $25 and $50), but nobody spends them: the gold is worth far more than the face value.

1991 Gold Eagle by the numbers

The Mint sold 243,100 one ounce bullion Gold Eagles dated 1991. That ranks 11th lowest of the 39 bullion dates from 1986 to 2024.

Against the dates around it, 1991 bullion sales were 1.5 times fewer than 1990 and 1.1 times fewer than 1992.

Collector versions dated 1991 add up to 224,709 coins across 4 versions. The scarcest is the 1991 1 oz proof at 50,411; the most plentiful is the 1991 1/10 oz proof at 70,334.

Fractional bullion that year: 165,200 1/10 oz coins, 36,100 1/4 oz coins and 24,100 1/2 oz coins. The 1/2 oz is the scarce size of the year.

What to check on yours

• Weigh and measure it. A genuine one ounce Gold Eagle weighs 33.931 g and measures 32.7 mm; the fractional sizes are 3.393 g (1/10 oz), 8.483 g (1/4 oz) and 16.965 g (1/2 oz). Fakes are usually the wrong weight or the wrong thickness.
• Try a magnet. Gold is not magnetic, so a coin that sticks is not genuine. A coin that does not stick still needs the other checks.
• Look for the mint mark. Bullion strikes have none; proofs and burnished coins carry a small letter. A mirror field with frosted design means a proof, a soft satin look means burnished.
• Handle it by the edge and never clean it. Fingerprints, wiping and polishing leave marks that cost collector versions much of their premium.
• Keep the original capsule, box and certificate with collector versions. Coins that come with them are easier to sell and more likely to bring their full premium.

The 1991 half ounce bullion coin is the key date of the regular bullion series. It carries a collector premium well above metal value and is the closest thing to a significant rarity among regular bullion Gold Eagles. Demand is strongest for certified coins in high grades. The quarter ounce at 36,100 also brings a collector premium. The proofs and the tenth and one ounce bullion coins trade much closer to their gold content. Even a lightly marked raw coin sells above metal value, but certification usually makes it easier to sell.

Roman numeral years (1986 to 1991)

The Gold Eagle arrived in 1986 with a bang. Bullion buyers took 1,362,650 one ounce coins and more than half a million of each fractional size that first year, while the Mint sold 446,290 one ounce proofs. Every coin from these first six years carries its date in Roman numerals, from MCMLXXXVI to MCMXCI, which makes the era easy to spot at a glance.

Proofs were added a size at a time. Only the one ounce came in proof in 1986. The half ounce joined it in 1987 and from 1988 all four sizes were offered, with sales per size landing between about 44,000 and 144,000 from 1988 to 1991. Collectors were buying steadily even as bullion demand for the smaller coins faded fast.

That fade is what makes this era interesting. The half ounce bullion coin fell from 599,566 in 1986 to 131,255 in 1987, then to 45,000 in 1988, 44,829 in 1989, 31,000 in 1990 and finally 24,100 in 1991, the lowest bullion figure from 1986 to 2024. The quarter ounce followed a similar path down to 36,100. Bullion coins were bought for their metal and handled freely, so nice examples of these fractional dates are harder to find than the mintages suggest. Collectors pay a premium for them, larger for coins in high certified grades. The one ounce bullion coins of the period, made in the hundreds of thousands or more, mostly trade on their gold content.
