1/20 oz Silver Libertad 2010: What It's Worth

If you inherited or found a tiny silver coin marked "1/20 Onza" with an angel on one side and an eagle on the other, here is the straight answer: the 2010 1/20 oz Silver Libertad is a small silver bullion coin with a low mintage of 12,000 pieces. In 2026, that low number is what gives it collector value above its metal, though it is still a modest coin, not a five-figure rarity.

Quick answer: what it's worth in 2026

This is a fractional Onza Libertad, meaning it holds just 1/20 of a troy ounce of pure silver. The Onza Libertad ("Liberty Ounce") is Mexico's flagship modern silver coin series, minted by Banco de México, the country's central bank. The 1/20 oz version is the smallest fraction in the set.

Because it contains so little silver (about 1.5552 grams), its melt value is only a fraction of a dollar. The real value comes from the 2010 date's low mintage of 12,000 coins, which is small for the series. In practical terms, expect a range depending on condition:

• Circulated or handled (bullion strike): a few dollars over spot silver.
• Uncirculated with original satin finish: typically in the 15 to 40 USD range to collectors.
• Certified high grade (NGC/PCGS MS69 to MS70): can reach higher, sometimes 50 to 100+ USD when demand for the fractional set is strong.

These are collector ranges, not guaranteed sale prices. A single small coin sells for less than a complete 5-coin fractional set in original packaging, which is how many buyers prefer to acquire these.

The specs that matter (keep these to check yours)

The front (obverse) shows the Mexican coat of arms, an eagle on a cactus eating a serpent, with the legend "ESTADOS UNIDOS MEXICANOS." The back (reverse) shows the Winged Victory, the golden angel from Mexico City's Independence monument, in front of the two volcanoes Popocatépetl and Iztaccíhuatl, with the "Mo" mint mark and the year.

Why the low mintage matters, and why it doesn't make it a fortune

A mintage of 12,000 is genuinely low, and low-mintage fractional Libertads are the ones collectors chase. The most sought-after fractional dates from the 1990s can command hundreds of dollars in top grade. The 2010 is not one of those key dates, so keep expectations realistic.

The myth to kill: "it's silver and old, so it must be worth a lot." A 2010 coin is not old, and 1/20 oz is a very small amount of silver. What gives this piece any premium at all is collector demand for the complete fractional set and the specific mintage number, not age or precious metal weight.

How to tell if yours is genuine

Weigh it on a jewelry scale and measure it with calipers. A genuine coin weighs 1.5552 grams and measures 16 mm. Fakes usually miss on weight or diameter, show flat or mushy relief, or have uneven color. Be suspicious of any coin offered far below the value of its silver content. For a piece this small, most fraud is either counterfeit or post-mint damage passed off as a mint error.

Where to sell it

• A verified coin shop from the Pesoteca dealer directory can appraise it on the spot.
• The Pesoteca buy-and-sell forum puts you in front of collectors who actually want fractional Libertads.
• Photograph the obverse, reverse, and edge before you sell, and check the range in this guide first.

Avoid dumping it to the first bidder on social media. Because it is a precious metal coin, only buy or sell with someone who will show you the piece and its weight so you can verify before paying.

1/20 troy oz Libertad silver 2010 Regular BU

This piece is the 1/20 troy oz silver Libertad, struck by the Mexican Mint (Casa de Moneda de México) in 2010 in its Regular BU version.

Specifications. It contains 1.55 g of pure silver, .999 fineness, and measures 16 mm in diameter. The reverse bears the effigy of the Angel of Independence, adopted 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 identifying 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 example 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 2010 Felipe Calderón Hinojosa was in office. A double national anniversary: the Bicentennial of the start of Independence and the Centennial of the start of the Mexican Revolution. Silver closed at 30.63 USD per troy ounce.

Regular BU finish. The Regular finish, catalogued by Banxico as satin or BU, is obtained with dies that have no special polishing. The result is an even matte luster across the entire 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 striking premium. It is the version hunters seek to build the complete set by year without decapitalizing on every piece.

Mintage. Banxico reported in its official tables a mintage of 14,365 pieces for this combination of fraction, year and finish. That figure is the basis for gauging the relative scarcity of the piece within the program.
