1/10 oz Gold Libertad 2013 Proof: Value & Prices

If you have a 2013 1/10 oz Gold Libertad Proof, you are holding one of the scarcer modern Mexican gold coins: only 300 were struck. Its value in 2026 starts at its gold content (roughly 3.11 grams of pure gold) and climbs well above melt because of that tiny mintage and the proof finish.

The Onza Libertad is Mexico's official bullion series, minted by Banco de México (Banxico) and produced at the Casa de Moneda de México, the national mint. "Onza" means ounce, and "Libertad" (Liberty) refers to the Winged Victory figure on the design. The 1/10 oz is the smallest common gold fraction in the series, so it is affordable to own but scarce in proof.

What the 2013 1/10 oz Gold Libertad Proof is worth

Two things set the floor and the ceiling on this coin:

• Metal value (the floor): it contains 3.11 grams of gold at .999 fineness, which is 1/10 of a troy ounce. Whatever gold is trading at, take one-tenth of the spot price and that is the absolute minimum this coin is worth. Even damaged, it never drops below melt.
• Rarity and proof premium (the ceiling): with only 300 pieces minted and a proof finish (mirror fields, frosted relief), a graded, intact example trades well above melt to collectors. Small mintages like this are what separate a Libertad from a generic gold round.

Proof coins from Banxico are sold in official packaging. If yours still has the original Banxico capsule, box, and certificate, it is worth more than a loose coin. Collectors pay for the complete presentation.

Coin	Year	Mintage	Gold content	Value driver
1/10 oz Gold Libertad Proof	2013	300	3.11 g, .999 fine	Melt value plus a strong low-mintage proof premium

We do not quote a fixed dollar price because the number moves with the gold market every day and with the grade of your specific coin. A worn or cleaned example sells near melt. A pristine, graded Proof-70 with original packaging can command a solid multiple of its gold value. Check the current gold spot, then compare graded sales.

Specifications (verify yours against these)

• Weight: 3.11 grams
• Diameter: 16 millimeters
• Metal: gold, .999 fine (99.9% pure)
• Edge: reeded
• Finish: proof (mirror fields, frosted devices)
• Mintage: 300 pieces
• Series: part of the Onza Libertad line
• Era: Nuevos Pesos and modern issues

Any coin claiming to be this issue that does not hit 3.11 grams and 16 millimeters is either damaged or fake.

Is it actually rare?

Yes, by mintage. Three hundred struck is genuinely low for a modern issue. That does not automatically mean it sells for a fortune, because it is still a modern bullion coin with a firm melt floor, but the scarcity gives it a real collector premium over the plain gold value. The condition of yours decides where in that range it lands.

A quick note on "errors." Genuine mint errors (off-center strikes, die rotation, doubling) can raise value if verified. Most "errors" people post online are post-mint damage: scratches, dings, and corrosion, which lower value instead. If you think yours has a true error, get it looked at before you assume it is worth extra.

How to tell if yours is genuine

1. Weigh it. Use a jewelry scale. It must read 3.11 grams. Gold is dense, so fakes made of cheaper metal usually come in light or oddly sized.
2. Measure it. A caliper should show 16 millimeters across.
3. Check the strike. A real proof has deep mirror fields and crisp frosted relief. Flat, mushy detail is a red flag.
4. Be suspicious of bargains. Any offer far below the gold value is almost always a fake or a scam. Real gold does not sell cheap.

Where to sell it

Because this is a precious-metal coin, sell where the buyer values it in front of you and you can verify the payment:

• A verified numismatic dealer from the Pesoteca directory will appraise it on the spot and pay based on gold spot plus the collector premium.
• The Pesoteca buy-and-sell forum connects you directly with collectors who want this specific issue.

Before you sell, photograph the obverse, reverse, and edge, and note whether you still have the original Banxico packaging. Do not dump it to the first buyer on social media, and never hand over a gold coin before payment clears.

This piece is a Libertad gold 1/10 ounce struck in 2013 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.

Enrique Peña Nieto (2012-2018). Energy reform in December. Gold spot closed at 1,204 dollars per ounce (-28 percent for the year) and FIX at 13.08 pesos.

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 407 pieces against 2,615 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.
