1 oz Silver Libertad 2011 Proof: Value & Prices

If you have a 2011 Proof Silver Libertad in its original case, you own one of the lower-mintage modern bullion issues from Mexico: only 10,000 were struck. In 2026, expect roughly USD 90 to USD 250 depending on condition, well above its raw silver value. This is not a rare classic worth thousands, but it does carry a real collector premium over melt.

What you actually have

The Onza Libertad ("Libertad Ounce") is Mexico's flagship silver bullion coin, struck by the Casa de Moneda de México, the oldest mint in the Americas. The Proof version is the collector finish: mirror-like fields and frosted, matte design elements, sold by Banco de México (Banxico) in a sealed presentation case rather than as plain bullion.

Specifications for the 2011 Proof one-ounce coin:

Spec	Detail
Metal	Silver .999 fine
Weight	39.91 grams (1 troy ounce of pure silver)
Diameter	45.15 mm
Edge	Reeded
Finish	Proof
Mintage	10,000 pieces
Series	Onza Libertad

The coin shows the Winged Victory (Angel of Independence) with the volcanoes Popocatépetl and Iztaccíhuatl on the reverse, and Mexico's national coat of arms on the obverse. Note the 39.91-gram weight: that is a full troy ounce of pure silver plus a fraction, because .999 fine leaves almost no room for alloy.

What it's worth in 2026

Two things set the price: the silver content (a hard floor) and the collector premium from the low 10,000 mintage and proof finish.

• Melt floor: one troy ounce of pure silver. Whatever silver spot is on the day you sell, that is the absolute minimum a dealer will pay.
• Collector value: the proof premium and low mintage push this well above melt for clean examples still in the Banxico case.

Rough ranges by condition:

Condition	Typical range (USD)
Damaged / cleaned / no case	Near melt value
Proof, original Banxico case, no capsule spots	90 to 150
Certified PF69 (NGC/PCGS)	130 to 200
Certified PF70 (top grade)	200 to 350+

These are guide ranges, not guarantees. The 2011 Proof is one of the more sought dates in the series thanks to its 10,000 mintage, but it is not a five-figure rarity. Anyone telling you a standard 2011 Proof Libertad is worth thousands is quoting fantasy, unless it is a flawless PF70 in a strong market.

The myth to ignore

Most "rare Mexican coin worth a fortune" stories online are clickbait. A modern proof bullion coin like this has a known, published mintage, so its value is predictable. What kills value fastest: cleaning the coin, handling the proof surface with bare fingers, or losing the original case and certificate. Milk spots (cloudy white patches common on .999 silver) also drag the price down toward melt.

How to check what yours is worth

1. Confirm the finish. A proof has mirror fields and frosted designs. A plain business-strike 2011 Libertad is a different, more common coin. Compare against images in our conservation grade guide.
2. Weigh and measure it. Use a jewelry scale and a caliper: it should hit 39.91 grams and 45.15 mm. Wrong weight or diameter is a red flag for a fake.
3. Grade it. A certified PF69 or PF70 from NGC or PCGS can more than double the value of a raw coin. Worth the fee only for clean, spot-free examples.
4. Check silver spot. Multiply the current price of one troy ounce of silver by one. That is your melt floor before any premium.

Where to sell it

Sell where buyers understand proof bullion and will pay the premium, not just melt. A verified shop in the Pesoteca dealer directory can value it on the spot, or list it in the Pesoteca buy-and-sell forum where collectors compete on price. Photograph the obverse, reverse, edge, and the original case before you sell. Avoid dumping it to the first Facebook offer, and never sell for less than the silver value.

1 troy oz Libertad silver 2011 Proof

This piece is the 1 troy oz silver Libertad, struck by the Mexico City Mint in 2011 in its Proof version.

Technical data. It contains 31.1 g of pure silver, .999 fineness, and measures 40 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, along with other historical coats of arms as an identity mark of the family.

Role within the set. It's the flagship piece of the series. Its annual mintage is the highest of the whole set, and it is Mexico's official bullion reference. Collectors and physical silver investors always seek this denomination first.

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 historic Hunt record of 1980. It closed the year at 28.18 USD.

Proof finish. The Proof finish, also known as mirror, is achieved by polishing the dies to a mirror sheen in the fields, while the reliefs are frosted by micro-blasting. The piece comes off the press ready to be displayed: it isn't exposed to the air or handled without gloves. Banxico delivers it in a sealed plastic capsule with an individually numbered certificate of authenticity. The Proof mintage is always far lower than that of the regular finish of the same year, and its price on the secondary market is usually between 40% and 80% above the equivalent BU version.

Mintage. Banxico reported in its official tables a mintage of 11,214 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.
