1/20 oz Silver Libertad 2007: Value & How to Sell

If you found a tiny Mexican silver coin marked "1/20 onza" dated 2007, here is the honest answer: as pure silver it holds a small floor value, but this particular version had a very low mintage of only 7,039 pieces. That low number is what can push a certified, high-grade example well above its metal weight. In 2026, this is one of the more collectible small Libertads for that reason.

What you actually have

The Onza Libertad is Mexico's official silver bullion series, minted by the Casa de Moneda de México (the national mint). "Onza" means ounce, and "Libertad" (Liberty) refers to the winged Victory figure on the coin. The full set runs from a 1-ounce coin down to fractional sizes, and the 1/20 onza is the smallest.

Your coin's specs, exactly as issued:

• Metal: .999 fine silver (99.9% pure)
• Weight: 1.5552 grams (1/20 of a troy ounce)
• Diameter: 16 mm
• Edge: reeded
• Design: the Mexican coat of arms with historic eagles and Códice Mendocino elements on the front (obverse); the Winged Victory of the Ángel de la Independencia monument, with the Popocatépetl and Iztaccíhuatl volcanoes behind, on the back (reverse)

This is part of the New Libertad Series, a design the mint introduced in 1996 and formalized by decree published in Mexico's official gazette (Diario Oficial de la Federación) on May 20, 1999.

Why the 2007 is worth a second look

Most fractional Libertads trade close to their silver content. The 2007 1/20 oz is different because of its mintage.

Banxico's official production table (CM10) reports 7,039 pieces struck in satin finish for 2007. For a bullion series, that is a genuinely small number. Low survival plus collector demand is what separates a coin worth a few dollars from one worth a real premium.

There are also mirror (proof-like) variants of the same year that are catalogued separately. The satin finish is the base version most people will encounter.

What it's worth in USD

Because this is a tiny silver coin, start with the floor: 1.5552 grams of .999 silver. At typical silver prices that metal content is only a couple of dollars. That is the absolute minimum a genuine piece is worth.

The collector premium is where the 2007 earns its keep:

Condition	What it means	Likely value (USD)
Circulated / handled	scratches, fingerprints, no certification	roughly 5 to 20
Uncirculated, raw	clean, never spent, not graded	20 to 60
Certified high grade (MS/PF 68-69)	slabbed by NGC or PCGS	80 to 250+

These are ranges, not guarantees. A tiny coin with a 7,039 mintage can spike when two serious collectors want the same slabbed example, and it can sit near melt when nobody's bidding. Grade and certification drive the number more than anything else.

How to tell if yours is genuine

Small silver coins get faked, so verify before you buy or sell:

1. Weight and size. A real one is 1.5552 grams and 16 mm across. If your scale and calipers say otherwise, be suspicious.
2. The ping test. Genuine silver gives a high, ringing tone when you balance it and tap it gently. Fakes with base metal sound dull and short.
3. Edge and detail. Look for the reeded edge and crisp design lines. Cast counterfeits often show mushy detail and a seam.
4. Certification. For any coin you think is high grade, NGC or PCGS grading is the final word. A slab confirms authenticity and grade in one step, and it's what buyers pay the premium for.

Where to sell it

Your best options in the US and internationally:

• NGC or PCGS dealers and shows. If the coin looks uncirculated, getting it certified first usually pays for itself on a low-mintage issue like this.
• Established coin dealers who handle world/Mexican coins. They'll appraise on the spot.
• Reputable online marketplaces and auction houses (Heritage and Stack's Bowers handle Mexican series). Good for graded pieces where buyers compete.
• The Pesoteca community, where collectors of Mexican coins buy, sell, and confirm authenticity.

Whatever route you take, photograph the obverse, reverse, and edge, and always insist on weight and clear photos from any seller before money changes hands.

1/20 troy oz Libertad silver 2007 Regular BU

This piece is the 1/20 troy ounce silver Libertad, struck by the Mexican Mint in 2007 in its Regular BU version.

Technical data. It contains 1.55 g of pure silver at .999 fineness 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, alongside 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 initiation 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 striking cost is spread across fewer grams.

Context of the year. In 2007 Felipe Calderón Hinojosa governed. First full year of the Calderón administration. Silver continued its upward trend on its way to 13.38 USD per troy ounce on average.

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

Mintage. Banxico reported in its official tables a strike of 7,039 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.
