1/2 oz Gold Libertad 1982

The 1982 half-ounce Gold Libertad is worth real money, but for a simple reason: it contains a half ounce of pure gold. As of 2026, that puts a hard floor under it, typically north of 1,000 USD depending on the daily gold price, with collector premiums pushing certain graded examples higher. If you inherited or found one, this is not a coin you sell for pocket change.

What you actually have

The Libertad (Spanish for "Liberty") is Mexico's official bullion series, its answer to the American Gold Eagle or the Canadian Maple Leaf. It was created for investors who want to own gold in coin form. The reverse shows the Winged Victory statue from Mexico City's Angel of Independence monument, with the volcanoes Popocatépetl and Iztaccíhuatl behind her. The obverse carries the Mexican national coat of arms ringed by historic seals.

Because it is a bullion coin, its baseline value is the gold inside it, not its age. A 1982 date sounds old to a US buyer, but for this series it is normal circulation-era production, not a scarce key date.

Specifications

Spec	Detail
Gold content	1/2 troy ounce, .999 fine (99.9% pure gold)
Weight	15.5515 g
Diameter	29 mm
Edge	Reeded
Mint	Casa de Moneda de México (Mexican Mint)
Design era	1981-1995 original die ("cuño gordita")

The gold program launched in 1981, a year before the silver version, and kept this same design through 1995. Mexican collectors call this the "cuño gordita" (roughly, "chubby die"), the original engraving before the modern redesign that arrived later in the decade.

What it's worth in 2026

Start with the metal. A half troy ounce of pure gold sets the floor. When spot gold trades around 2,300 USD per ounce, the melt value of this coin is roughly 1,150 USD. That number moves every day with the gold market, so check the live gold price and divide by two for a quick estimate.

On top of melt, expect a premium:

1. Raw, circulated coins trade close to melt plus a small dealer margin. Think melt value plus 3% to 10%.
2. Uncirculated examples carry more, since early-date Gold Libertads in top condition draw collector demand beyond investors.
3. Graded coins in high Mint State (certified MS-67, MS-68 or better by NGC or PCGS) can bring meaningful premiums over melt, especially for lower-mintage early years.

The honest range: for most 1982 examples you are looking at melt value plus a modest premium. Only a certified top-grade coin justifies paying well above the gold content.

The myth to ignore

Search results will tell you old Mexican gold coins are worth a fortune. For this piece, that is misleading. The 1982 half-ounce Libertad is valuable because it is gold, period. Its collector premium is real but modest. Do not let anyone talk you into a wild "rare 1982" price. If you want the classic Mexican gold piece with a genuine collector story, that is the Centenario 50 pesos gold coin, a different animal.

How to check yours before you sell

Authenticity matters most here because the value is tied to precious metal, and fakes exist.

• Weigh it. A jewelry scale should read 15.5515 g. A fake will usually miss this.
• Measure it. The diameter is 29 mm. Use calipers.
• Inspect the relief. Genuine coins have crisp, deep detail. Flat or mushy strikes, wrong color tone, or seams are red flags.
• Be suspicious of a bargain. Any offer far below the gold melt value is almost certainly a fake or a scam.

For peace of mind on a coin this size, third-party grading (NGC or PCGS) confirms both authenticity and grade in one step.

Where to sell

Sell where you can see the buyer weigh and inspect the coin, and where you get metal-based pricing without a middleman markup:

• A verified coin shop from the Pesoteca dealer directory that appraises on the spot.
• The Pesoteca buy-and-sell forum, collector to collector.

Photograph the obverse, reverse, and edge in good light, and know the current gold price before you talk numbers. Do not dump it to the first Facebook offer.

This piece is a Libertad gold 1/2 ounce struck in 1982 in the regular (bullion satin) finish. The series was created by DOF decree of April 8, 1981, and added the 1/2, 1/4, 1/10, and 1/20 fractions from 1991.

José Lopez Portillo was closing out his term before Miguel de la Madrid took office on December 1. It was the year of the bank nationalization (September 1) and of the debt crisis: the peso went from 26 to 148 per dollar over the year and the gold spot averaged 375 dollars per ounce.

Fraction: pure gold 15.552 grams, .999 fineness, total weight 17.27 grams, 29 millimeter diameter. The half ounce balances liquidity and heft: it moves enough gold to be a real store of value and remains tradable peer-to-peer. Premium over spot 5 to 10 percent, higher than the full ounce because of the prorated minting cost.

Regular (bullion satin): matte-brilliant fields and satin relief, a single press strike. Wholesale distribution for physical gold investment, the largest mintage of the year and the natural premium reference against spot.

Banxico CM10 does not publish mintages prior to 2000; the data are found in Krause (KM#630 to KM#674 depending on year and fraction).

The regular strike is bought for its gold content at a low premium over spot. Verify weight, diameter, and reeded edge; compare the premium against Banxico Direct before accepting a middleman.
