1/20 oz Silver Libertad 2011 Value

The 2011 1/20 oz Silver Libertad is worth more than its tiny silver content because only 15,000 were struck. Most raw examples trade in the range of 15 to 40 USD, but a top-graded certified piece can push well past 100 USD. Here's how to tell what yours is worth.

What this coin actually is

The Libertad is Mexico's flagship modern bullion and collector series, issued by Banco de México (the country's central bank). "Onza" is Spanish for ounce, and this is the smallest fractional size in the family: 1/20 of a troy ounce.

Quick specs, straight from Banco de México:

• Metal: .999 fine silver (pure silver)
• Weight: 1.5552 grams (1/20 troy ounce)
• Diameter: 16 mm
• Edge: reeded
• Finish: bullion (satin), the investment version with a uniform satin surface
• Mintage: 15,000 pieces
• Mint mark: "Mo" (Mexico City mint)

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 Mexico City's Angel of Independence monument, framed by the Popocatépetl and Iztaccíhuatl volcanoes, with the year 2011.

How much is it worth in 2026?

Don't start with silver melt. At 1.5552 grams of pure silver, this coin holds only a fraction of a dollar in metal. The value here comes from low mintage and collector demand, not bullion.

At 15,000 pieces, the 2011 1/20 oz is genuinely scarce compared to the larger one-ounce Libertads that run into the hundreds of thousands or millions per year. That scarcity is what supports the premium.

Condition	Typical value (USD)
Circulated / handled	12 to 20
Uncirculated, raw (BU)	20 to 40
Certified MS-69 (NGC/PCGS)	40 to 80
Certified MS-70 (top pop)	100+

These are collector ranges, not fixed quotes. The fractional Libertads are thin-market coins: prices swing with how many collectors are actively completing a set at any given moment. A raw coin with visible fingerprints or milk spots (a common issue on silver Libertads) sits at the low end regardless of date.

The myth: "low mintage means it's worth a fortune"

15,000 is a small number, so people assume big money. In reality, the fractional silver Libertads are collected by a dedicated but limited group, mostly set-builders who want the full 1/20, 1/10, 1/4, 1/2 and 1 oz run for a given year. That caps how high prices go. This is a solid, respectable collector coin, not a four-figure rarity. Anyone quoting you hundreds of dollars for a plain circulated example is overreaching.

Where real money does appear: certified perfect grades. An NGC or PCGS MS-70 with a low population can command a strong premium because grade-registry collectors compete for the finest known. If your coin has been in a drawer getting handled, it is not an MS-70.

Does it have valuable mint errors?

Genuine mint errors (off-center strikes, die rotation, doubled dies, recognized varieties) can multiply value if they're real and verifiable. But most "errors" people post online are post-mint damage: dings, scratches, corrosion, or milk spotting, none of which add value. If you think you have a true error, get it looked at before you get excited.

How to check what yours is worth

1. Verify weight and diameter. Use a jewelry scale and calipers. It should weigh 1.5552 g and measure 16 mm. Fakes usually miss on weight or diameter, or show flat, mushy relief.
2. Grade honestly. Look for wear, scratches, fingerprints and milk spots under good light. Condition is the single biggest price driver here.
3. Consider certification. For a coin this small in value, professional grading (NGC/PCGS) only makes sense if you believe you have a near-perfect example. For an average coin, the grading fee can exceed the coin's value.
4. Photograph both sides and the edge before you sell, so a buyer can assess it remotely.

Where to sell it

For the best result, use a verified numismatic shop from the Pesoteca directory, which can value it on the spot, or the Pesoteca buy-and-sell forum where set-builders actually want fractional Libertads. Because this is a precious-metal coin, only deal with buyers who let you see the piece and confirm the weight first. Skip dumping it to the first Facebook offer, and always cross-check the grade and both-side photos against the ranges above.

Want a second opinion before you sell? Post clear photos in the Pesoteca forum and let collectors who chase these fractionals tell you what yours is really worth.

1/20 troy ounce Libertad silver 2011 Regular BU

This piece is the silver Libertad of 1/20 troy ounce, struck by the Mexico City Mint in 2011 in its Regular BU version.

Technical data. It contains 1.55 g of pure silver at .999 fineness and measures 16 mm in diameter. On the reverse it bears the effigy of the Angel of Independence, adopted by Banxico as the official symbol of the series since 1981. On the obverse appears 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 is the smallest fraction of the set. It serves as an entry piece, a gift, or a first contact with the series: it costs little per specimen but carries the highest premium of the family over the value of the silver it contains, because the die cost is spread over fewer grams.

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

Regular BU finish. The Regular finish, cataloged by Banxico as satin or BU, is produced with dies without special polishing. The result is an even matte shine over the entire surface, without mirror contrast between fields and reliefs. It is the traditional bullion finish: it is bought for its weight in pure silver plus a modest die premium. It is the version hunters look for to build the complete set by year without decapitalizing on each piece.

Mintage. Banxico reported in its official tables a strike of 24,723 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.
