1/2 oz Gold Libertad 2015: Value & Mintage of 517

If you inherited or found a 2015 1/2 oz Gold Libertad, you have one of the scarcer modern Mexican gold coins. With a reported mintage of just 517 pieces, this coin sells for a premium over its gold content, not the melt-only price most bullion Libertads bring. In 2026, that low mintage is what drives the number.

What this coin actually is

The Libertad (full name Onza Libertad) is Mexico's official gold and silver bullion series, struck by the Casa de Moneda de México, the national mint. The 1/2 onza is the half-ounce gold version. This 2015 issue was made in a satin finish and, unlike the standard bullion runs of hundreds of thousands, only 517 pieces were struck.

That number is the whole story. A common-date Gold Libertad tracks the price of gold with a small collector premium. A 517-piece issue is a genuine low-mintage modern rarity, and buyers pay for scarcity on top of the gold.

Obverse: the national coat of arms (Libertad design), mirror field.

Reverse: the Winged Victory (Ángel de la Independencia) standing before the volcanoes Popocatépetl and Iztaccíhuatl, with the inscription "1/2 ONZA TROY DE ORO PURO" (half troy ounce of pure gold).

The weight and diameter are your first authenticity test. This coin contains half a troy ounce of pure gold and weighs 15.5517 grams. If yours weighs noticeably less or measures off from 29 mm, treat it as suspect. Gold counterfeits, usually made in lower fineness, almost always fail on weight.

What it's worth

Two things set the price: the current gold spot price (a half-ounce floor that never disappears) and the collector premium driven by the 517-piece mintage.

Because it holds half a troy ounce of .999 gold, this coin has a hard bullion floor equal to half the current gold spot price. On top of that floor, the low mintage adds a real numismatic premium, so a 2015 1/2 oz Libertad sells well above melt, unlike ordinary-year bullion Libertads that trade near spot.

Grade decides where you land above the floor. A certified example graded by NGC or PCGS (MS or PF depending on strike) commands more than a raw, uncertified coin, and pieces still in the original Banxico packaging carry an extra premium. For a scarce gold coin like this, professional grading is worth it: it settles authenticity and grade in one step and protects your resale value. See the Mexican coin grading guide to estimate your coin's condition before you sell.

Is it rare? Yes, and here's why

Most "old Mexican coin worth a fortune" claims fall apart the moment you check the mintage. This one holds up. A modern issue of 517 pieces is genuinely scarce, and scarcity plus gold content is exactly the combination that supports strong prices. The official mintage figure is documented at 517, which puts it in low-mintage territory for the entire Libertad series.

That said, keep expectations honest. This is a valuable coin worth a solid premium over its gold, not a six-figure trophy. The number that matters is the gold price plus a scarcity premium, and both are real.

How to tell if yours is genuine

• Weigh it. 15.5517 grams. A jeweler's scale settles most fakes on the spot.
• Measure it. 29 mm diameter, reeded edge.
• Check the reeding and strike. The satin finish and sharp design detail are hard to fake convincingly.
• Get it certified. For a gold coin at this value level, NGC or PCGS grading is the definitive safeguard. It confirms authenticity and locks in a grade buyers trust.

Where to sell it

With precious-metal coins, sell only to buyers who inspect the coin and its weight in front of you, and always show clear photos of obverse, reverse, and edge.

• A verified numismatic shop from the Pesoteca directory will appraise it on the spot at a fair price.
• The Pesoteca buy-and-sell forum connects you directly with collectors who know this issue.

Before you sell, photograph the coin (both sides and the edge), note whether you have the original Banxico packaging, and compare against the grade ranges above. Don't dump a 517-piece gold coin to the first offer on general marketplaces, where counterfeits are most common.

This piece is a Libertad gold 1/2 oz Onza struck in 2015 in regular finish (bullion satin). The series was born by DOF decree of April 8, 1981, and added the 1/2, 1/4, 1/10 and 1/20 fractions starting in 1991.

Enrique Peña Nieto. A year of a strong dollar and expectations of a Fed hike. Gold spot closed at 1,060 dollars per ounce and the FIX at 17.20 pesos.

Fraction: pure gold 15.552 grams, fineness 0.999, total weight 17.27 grams, diameter 29 millimeters. The half ounce balances liquidity and body: it moves enough gold to be a real reserve while remaining peer-to-peer tradable. Premium over spot 5 to 10 percent, higher than the full ounce due to prorated minting cost.

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

Banxico CM10 (consulted 2026-05-27) records 517 pieces against 1,226 pieces in the Proof version of the same year. The differential explains the price gap between variants.

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