1/20 oz Gold Libertad 2002: Value & How to Sell

If you inherited or found a tiny gold coin marked "1/20 Onza" with an angel on the back, you have a Mexican Gold Libertad, one of the few Mexican coins that carries real value in 2026. The 2002 date is genuinely scarce: only 3,084 pieces were struck. Its floor is its gold content, and the low mintage adds a collector premium on top.

What it's worth right now

This coin has two prices working at once, and you need to understand both before you sell.

The metal floor. The 1/20 Onza Libertad contains exactly 1/20 of a troy ounce of pure .999 gold. It weighs 1.5552 grams. Because gold trades on a global spot market, this coin can never be worth less than its melt value. As of 2026, that floor is roughly 5 to 6 percent of the current gold spot price. When gold sits near 2,600 USD per ounce, the raw gold in the coin is worth around 130 USD. That number rises and falls with the gold market, so check the live spot price the day you buy or sell.

The collector premium. Here is where the 2002 stands apart. Banxico (Mexico's central bank) reports an official mintage of just 3,084 pieces in satin finish for that year. That is a low number for a bullion series, and low mintage is what drives collector demand. A raw 2002 in good condition typically trades meaningfully above melt, and a certified example (graded by NGC or PCGS in high mint state) can carry a premium of several times the gold value. Expect a range from roughly 200 USD for a raw circulated piece up to several hundred dollars for a top-graded example, depending on grade and demand.

Coin	Year	Mintage	Gold content	Typical value range (USD)
1/20 oz Gold Libertad	2002	3,084	1.5552 g (.999)	~130 (melt) to several hundred (graded)

What you actually have

The Onza Libertad is Mexico's official bullion and collector series, struck by the Casa de Moneda de México (the Mexican Mint). "Onza" means ounce, and "Libertad" refers to the design. The gold version comes in five sizes: 1 oz, 1/2 oz, 1/4 oz, 1/10 oz, and the smallest, the 1/20 oz you likely have.

The design is the modern series authorized by the 1999 decree, called the "Nueva Serie Libertad." The front shows the Mexican national coat of arms surrounded by historic eagles from the Codex Mendoza. The back shows the Angel of Independence (El Ángel), the winged victory statue from Mexico City, with the Popocatépetl and Iztaccíhuatl volcanoes behind her. The coin measures 13 mm across with a reeded (grooved) edge.

If you have larger Libertads too, the 1 oz silver and 1 oz gold versions are the ones collectors chase hardest. See our guide to the Onza Libertad series for the full lineup.

The myth: "a gold coin, so it must be worth thousands"

No. Because this is a bullion coin, its value is anchored to the small amount of gold inside it, and 1/20 of an ounce is not much metal. Most 1/20 oz Libertads across all years trade for a modest premium over melt. The 2002 is worth more than average because of its low mintage, not because it is old or because gold is precious in the abstract. A common-date 1/20 Libertad from a high-mintage year is worth close to melt and nothing more.

How to tell if yours is genuine

Counterfeit gold is real, and it usually fails on physical specs. Check these:

• Weight: a genuine coin weighs 1.5552 grams. Use a scale accurate to 0.01 g. Fakes struck in lower-purity gold or base metal almost always miss the weight.
• Diameter: 13 mm across.
• Edge: reeded (fine vertical grooves).
• Finish: the 2002 was issued in satin finish.

If the weight or diameter is off, it is not authentic. For any piece you plan to buy or sell above a few hundred dollars, the safest move is professional certification by NGC or PCGS, the two grading services collectors trust. A certified coin sells faster and for more.

Where to sell it

Because this is a precious-metal coin, only deal with buyers who will weigh and inspect it in front of you, and verify before you pay.

• Verified coin dealers from the Pesoteca shop directory will appraise it on the spot and pay closer to fair value than a general gold buyer.
• The Pesoteca buy-and-sell forum connects you directly with collectors, /foro/compra-venta, which often gets you a better price than a dealer's buy rate.
• A local coin shop or coin show works if you want cash the same day. Get more than one offer.

Before you sell, photograph the front, back, and edge, weigh the coin, and check the value ranges on this page so no one lowballs you. Avoid dumping it to the first buyer on social media.
