1/10 oz Gold Libertad 2011 Proof: Value & Prices

If you found a small gold coin marked "1/10 Onza" with an angel and a mountain scene, dated 2011, you have a 1/10 oz Gold Libertad Proof, one of only 1,100 pieces struck that year. This is a real gold bullion coin with a mintage low enough to matter to collectors, so its value sits well above the raw metal.

What it's worth in 2026

This coin has a hard floor and a collector premium on top:

• Metal floor: it contains exactly one-tenth of a troy ounce of pure gold (0.999 fine). Its melt value is one-tenth of the current gold spot price. That number moves daily with the market, so a plain, worn 1/10 oz gold coin never sells for less than that.
• Collector premium: because only 1,100 of the 2011 Proof were made, and because Proof coins have mirror fields and frosted designs that must stay pristine, examples in original Banco de México (Banxico) packaging trade at a premium over melt. A sealed, flawless piece commands more than a loose, handled one.

Expect a range from melt value on the low end to a meaningful premium above spot for a graded or sealed Proof in top condition. The exact figure depends on gold spot the day you sell, the coin's grade, and whether you still have the original Banxico blister/case.

What is the Libertad?

The Onza Libertad is Mexico's official bullion series, struck by the national mint under Banco de México (the country's central bank). The design shows the Winged Victory (the "Angel of Independence") on the reverse and the national coat of arms on the obverse. Libertads come in gold and silver, in sizes from 1/20 oz up to full and multi-ounce pieces. The 1/10 oz gold is one of the smaller gold fractions. You can read more about the full Onza Libertad series and how the sizes compare.

Proof coins are struck specially for collectors on polished dies, giving the deep mirror background and frosted design that distinguish them from regular bullion strikes. Handling a Proof with bare fingers leaves marks that lower its grade, so condition is everything.

The myth: "old" does not mean "valuable"

A 2011 coin is not old, and age is not what drives this piece. What drives it is the low mintage (1,100) plus the gold content. Ignore anyone claiming a common Libertad is worth thousands just because it looks special. The value comes from the metal floor and the small collector demand for the Proof, not from mystery or rarity hype.

How to check what yours is worth

1. Confirm it's the 1/10 oz gold Proof. Weigh it on a jewelry scale (it should read 4.09 grams) and measure the diameter (19.52 mm). A silver or clad fake will read wrong on weight or size.
2. Check the finish and packaging. A true Proof has mirror-like fields. If you still have the sealed Banxico blister or presentation case, keep it sealed. Original packaging adds value.
3. Grade the surface. Fingerprints, scratches, and hairlines all cut the price on a Proof. Review the coin grading guide before you handle it further.
4. Get a professional opinion. For a piece this small in gold, an in-person appraisal at a verified dealer confirms authenticity and grade on the spot.

How to tell if it's genuine

Gold fakes are usually caught on the scale. A real 1/10 oz Gold Libertad weighs 4.09 grams and measures 19.52 mm. Counterfeits tend to be off on weight or diameter, show flat, mushy relief, or the wrong color balance. Be suspicious of any offer priced far below the current gold value. That is the classic sign of a fake or a scam.

Where to sell it

Because this is a precious-metal coin, only deal with someone who inspects the piece and confirms its weight in front of you. Your safest options:

• A verified numismatic shop from the Pesoteca dealer directory, which can appraise and pay you on the spot at a fair price tied to gold spot.
• The Pesoteca buy-and-sell forum, where collectors deal directly.

Before selling, photograph the obverse, reverse, and edge, and check the current gold spot so you know your floor. Do not dump it to the first bidder on a social feed.

Think you might have a mint error or an unlisted variety? Post clear photos in the Pesoteca forum and let the community weigh in before you sell.

This piece is a Libertad gold 1/10 ounce struck in 2011 in Proof finish. The series was born by decree in the DOF on April 8, 1981, and added the 1/2, 1/4, 1/10, and 1/20 fractions from 1991.

Felipe Calderón. Year of gold's historical peak (1,895 dollars in September), spot closed at 1,566 dollars per ounce and FIX at 13.99 pesos due to the European crisis.

Fraction: pure gold 3.110 grams, 0.999 fineness, total weight 3.45 grams, diameter 22 millimeters. The tenth is the standard small fraction: entry into physical gold, gift, and a planchet test for a first purchase. Premium over spot 12 to 20 percent because of the die cost over little mass.

Proof: frosted mirror fields over matte relief, polished dies and multiple strikes. It ships encapsulated with an individual certificate. The Proof mintage is always a fraction of the regular, typically +40 to 100 percent over bullion.

Banxico CM10 (consulted 2026-05-27) records 351 pieces against 6,530 pieces in the regular version of the same year. The difference explains the price premium between variants.

The Proof is hunted for the complete set of fractions and for the certificate with original capsule. When buying one-on-one, check the capsule for scratches, the certificate tied to the piece, and compare the premium against the regular of the same year before dealing with a middleman.
