1/4 oz Silver Libertad 2011: Value & Prices

The 2011 quarter-ounce Silver Libertad is worth more than its silver, but not a fortune. With a low mintage of 15,500 pieces, it typically trades from about 25 to 60 USD depending on condition in 2026, with graded top-condition examples reaching higher. Here is what drives the price and how to check yours.

The Onza Libertad ("Liberty Ounce") is Mexico's flagship modern silver series, struck by the Mexican Mint for Banco de México, the country's central bank. The 1/4 oz is the small fractional size. It is real silver, so it always carries a floor value tied to the metal, plus a collector premium when the mintage is low, as it is here.

What you actually have

Feature	Detail
Coin	1/4 oz Silver Libertad
Year	2011
Metal	Pure silver, .999 fine
Weight	7.7758 g (1/4 troy ounce)
Diameter	27 mm
Edge	Reeded
Finish	Bullion (satin)
Mintage	15,500 pieces

The front (obverse) shows the Mexican national coat of arms, an eagle on a cactus devouring a serpent, with the legend "ESTADOS UNIDOS MEXICANOS." The back (reverse) shows the Winged Victory from the Angel of Independence monument in Mexico City, framed by the Popocatépetl and Iztaccíhuatl volcanoes, with the "Mo" mint mark and the year 2011.

What it's worth in 2026

Two things set the price: the silver content and the low mintage.

• Silver floor: it holds a quarter troy ounce of pure silver, so its value never falls below roughly a quarter of the current spot silver price. That is the baseline any dealer will pay.
• Collector premium: with only 15,500 struck, the 2011 quarter-ounce is scarcer than the common one-ounce Libertads that run into the millions per year. That scarcity adds a premium over melt.

As a rough guide for 2026:

Condition	Approximate value (USD)
Circulated / handled	25 to 40
Uncirculated (BU)	40 to 60
Graded MS-69 / MS-70	70 and up

These are ranges, not fixed prices. Silver spot moves daily, and a certified high-grade coin from NGC or PCGS can pull well above the raw-coin numbers. Sold together as part of a full 2011 fractional set (1/20, 1/10, 1/4, 1/2 oz), the pieces often bring more than sold one at a time.

Is it rare?

Scarce, not rare. A mintage of 15,500 is low for a modern bullion coin, which is why it holds a premium. But it is not a six-figure trophy piece. Anyone telling you a common-date fractional Libertad is worth thousands is inflating it. The real money in the Libertad series sits in the older 1990s fractional proofs and a few key low-mintage dates, not this one.

How to tell if it's genuine

The metal makes this coin a counterfeit target, so verify before you pay or sell.

1. Weigh it. A jeweler's scale should read 7.7758 g. A meaningful deviation is a red flag.
2. Measure it. Diameter should be 27 mm on a caliper.
3. Check the detail. Genuine Libertads show sharp relief on the Winged Victory and clean reeding on the edge. Fakes often look flat or soft.
4. Watch the price. Any offer far below the silver value is a warning sign, not a bargain.

When in doubt, third-party grading (NGC, PCGS) confirms both authenticity and grade, and it usually pays for itself on a low-mintage piece like this.

Where to sell it

For the best result, use a verified coin shop from the Pesoteca directory that appraises it in person, or the Pesoteca buy-and-sell forum among collectors. Because it is a precious-metal coin, only deal with buyers who let you confirm the weight and see the piece first. Photograph the obverse, reverse, and edge, and compare against the range in this listing before you accept an offer. Skip dumping it to the first bidder on social media.

1/4 troy oz silver Libertad 2011 Regular BU

This piece is the silver Libertad of 1/4 troy oz, minted by the Mexican Mint in 2011 in its Regular BU version.

Technical data. It contains 7.775 g of pure silver, .999 fineness, and measures 27 mm in diameter. The reverse bears the effigy of the Angel of Independence, chosen by Banxico as the official symbol of the series since 1981. The obverse shows the National Coat of Arms in its pre-1969 version, alongside other historical coats of arms as a mark of the family's identity.

Role within the set. It is the lower intermediate fraction of the set. Its size lets you appreciate the engraving of the Angel and the coat of arms without reaching the price of the full ounce. A good choice for anyone building the complete set by year without decapitalizing on each piece.

Context of the year. In 2011 Felipe Calderón Hinojosa was in office. Silver reached an intraday high near 49 USD per troy ounce in April, close to the 1980 Hunt historical record. It closed the year at 28.18 USD.

Regular BU finish. The Regular finish, cataloged by Banxico as satin or BU, is obtained with dies that have no special polishing. The result is an even matte luster across the whole surface, with no mirror contrast between fields and relief. It is the traditional bullion finish: bought for its weight in pure silver plus a modest die premium. It is the version collectors seek to build the complete set by year without decapitalizing on each piece.

Mintage. Banxico reported in its official tables a mintage of 32,377 pieces for this combination of fraction, year and finish. That number is the basis for measuring the relative scarcity of the piece within the program.
