1/20 oz Silver Libertad 2007 Proof: Value & Prices

If you inherited or found a tiny silver coin marked "1/20 Onza" with an angel on one side, you have a 1/20 oz Silver Libertad Proof from 2007. The short answer: this is one of the scarcer fractional Libertads, with only 4,000 pieces struck, so a genuine, well-preserved example is worth well above its melt value, often in the range of 40 to 90 US dollars depending on condition and whether it still has its original packaging.

That is the value-first answer. Now here is what you actually have, why the number is what it is, and how to check before you sell.

What this coin is

The Onza Libertad ("Libertad Ounce") is Mexico's flagship silver bullion series, minted by the Casa de Moneda de México and issued through Banxico (the Mexican central bank). The design shows the Winged Victory ("Ángel de la Independencia") on the reverse and the national coat of arms on the obverse.

Yours is the 1/20 ounce fractional size, the smallest in the series:

• Weight: 2.54 grams
• Diameter: 16 millimeters
• Metal: silver, .999 fine (99.9% pure silver)
• Edge: reeded
• Finish: Proof (mirror fields, frosted raised design)
• Year: 2007
• Mintage: 4,000 pieces

"Proof" is not a grade. It is a special striking method that produces a mirror-like background and frosted details. Proof coins were made for collectors, sold in sealed capsules, and were never meant to circulate. That matters for your value, because a Proof still in its original condition commands a premium over a handled one.

What it's actually worth

Because the coin contains only about 2.54 grams of silver, its melt value is small, usually a few dollars. The value here comes from scarcity and demand, not metal weight. With a mintage of just 4,000, the 2007 1/20 oz Proof is genuinely limited compared to the full one-ounce Libertads that were struck by the hundreds of thousands.

Grade / condition	Typical value (USD)
Damaged, cleaned, or hairlined	25 to 40
Choice Proof, no capsule	40 to 60
Gem Proof with original Banxico packaging	60 to 90
Certified top-grade (PF69/PF70 NGC or PCGS)	90 to 150+

These are collector ranges, not fixed prices. Actual figures move with the silver spot price and with how many examples surface for sale in a given year. A slab from NGC or PCGS (the two major third-party grading services) graded PF69 or PF70 sits at the top because certified condition removes the buyer's guesswork.

The original Banxico presentation packaging (capsule and case) adds real money. If you have the box and papers, do not throw them out.

The myth to avoid

Social media is full of claims that any old or unusual Mexican silver coin is worth thousands. For a fractional Libertad, that is not the reality. A common, handled 1/20 oz Libertad from a high-mintage year is worth close to melt. What lifts the 2007 Proof above that is the specific combination of a 4,000-piece mintage plus Proof finish plus preserved condition. Change any one of those and the value drops fast.

If you see one listed for hundreds of dollars, check whether it is actually certified in a top grade. Uncertified "gem" claims from a private seller are worth exactly what an appraiser confirms, not what the listing says.

How to tell if yours is genuine

Counterfeits of silver coins do exist, so verify before you pay or sell:

1. Weigh it. A genuine piece is 2.54 grams. Use a jewelry scale. Fakes are often off by a noticeable margin.
2. Measure the diameter. It should be 16 millimeters. Check with calipers.
3. Inspect the strike. Proof coins show sharp, frosted relief against a mirror field. Flat, mushy detail or dull fields is a red flag.
4. Be suspicious of bargains. Any offer well below the silver value plus a collector premium is a warning sign, not a deal.

For anything you are unsure about, get it graded by NGC or PCGS. Certification both authenticates the coin and locks in a grade that buyers trust.

Where to sell it

• A verified coin dealer will appraise it on the spot and make an offer. Use a reputable shop rather than a walk-in gold-buyer that pays melt only.
• Collector marketplaces and numismatic forums connect you directly with people who want fractional Libertads, which usually means a better price than a generic buyer.
• Certified coin listings (eBay, Heritage, Stack's Bowers) work best if the coin is already slabbed, since the grade is guaranteed.

Before you sell, photograph the obverse, reverse, and edge in good light, note the grade honestly, and compare against the ranges above. Do not dump it to the first offer on a general resale app.

If you want a second opinion on the grade or authenticity of your 2007 1/20 oz Libertad, post clear photos in the Pesoteca forum and let collectors weigh in before you sell.

1/20 troy oz Libertad silver 2007 Proof

This piece is the 1/20 troy ounce silver Libertad, struck by the Mexico City Mint in 2007 in its Proof version.

Technical data. It contains 1.55 g of pure .999 silver and measures 16 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, together 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 example but carries the highest premium in the family over the value of the silver it contains, because the die cost is spread over fewer grams.

Context of the year. In 2007 Felipe Calderón Hinojosa was in office. First full year of Calderón's administration. Silver continued its upward trend on its way to an average of 13.38 USD per troy ounce.

Proof finish. The Proof finish, also known as mirror, is achieved by polishing the dies to a specular shine in the fields, while the reliefs are frosted by micro-blasting. The piece comes off the press ready to be displayed: it is not 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 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 3,289 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.
