1/20 oz Silver Libertad 1994: Value & How to Sell

If you inherited a tiny Mexican silver coin with a winged angel on it, here's the honest answer: the 1/20 oz Silver Libertad from 1994 is worth a few dollars to around 40 USD for a certified high grade. It is real 99.9% silver, but it is a small fraction (about 1.55 grams), so the metal value alone is modest. The value comes from grade and collector demand, not age.

What you actually have

The 1/20 Onza Libertad ("Onza Libertad" means Silver Libertad Ounce, Mexico's flagship pure-silver bullion series) is the smallest fraction in the line. The obverse shows the Mexican coat of arms; the reverse shows the Winged Victory (the Angel of Independence) with the Popocatépetl and Iztaccíhuatl volcanoes behind her, one of the most recognized designs in Mexican numismatics.

Specifications, exact and verifiable:

• Metal: .999 fine silver (99.9% pure)
• Weight: 1.55 g
• Diameter: 16.08 mm
• Edge: reeded
• Year: 1994 (single-year strike within this issue)

This 1994 piece belongs to the 1982-1995 die variant that Mexican collectors nickname the "cuño gordita" (roughly, the "chunky die"): the original die, thicker and smaller in diameter than the modern version used since 1996. The 1/20 oz denomination was added to the series in 1991, when the Bank of Mexico introduced fractional sizes to the original line.

How much is the 1/20 oz Silver Libertad 1994 worth?

Because the coin is so small, its silver content sets a hard floor. Melt value at spot for 1.55 g of pure silver is only a couple of dollars. Above that floor, condition drives everything.

Condition	Approx. value (USD)
Circulated / handled	3 to 8
Uncirculated (raw)	10 to 20
Certified MS-67 to MS-68 (NGC/PCGS)	25 to 45+

Raw means ungraded. Certified means graded and sealed by NGC or PCGS, the two grading services collectors trust. A certified high-grade example can sell for several times a raw one, which is the single biggest lever on price for a coin like this.

The Bank of Mexico does not publish official mintage figures for Libertads from this era; public records begin only in 2000. So the exact 1994 mintage is undocumented. Do not trust forum figures claiming an exact number; none are confirmed. Scarcity here is inferred from how rarely top-grade examples appear, not from a published run.

The myth to avoid

A small old-looking silver coin is not automatically worth a fortune. This is a 1990s bullion fraction, not a rare colonial or revolutionary piece. If a listing claims a common 1994 1/20 Libertad is worth hundreds of dollars, it is either an error coin (rare and verifiable) or an overpriced listing. Genuine mint errors (off-center strikes, die rotation, doubling) can multiply value, but most "errors" circulating online are post-mint damage: scratches, corrosion, or dings, which lower value instead.

If you have a full set of Libertad fractions, the collectible interest rises. A single circulated 1/20 is a modest piece. For the larger sizes and their prices, see our guides to the Onza Libertad silver series and the Centenario gold coin.

How to tell if yours is genuine

1. Check the specs. It must weigh 1.55 g and measure 16.08 mm. A digital scale and caliper settle most fakes instantly. Wrong weight, wrong coin.
2. The ping test. Real silver rings with a high, sustained tone when you balance it on a fingertip and tap it lightly. Fakes sound dull and short.
3. Look at the edge. It should be cleanly reeded (grooved). Blurry or uneven reeding is a warning sign.
4. Certify anything you think is valuable. For a piece you believe is high grade or an error, NGC or PCGS certification is the definitive proof of authenticity and grade.

Where to sell it

For a coin in this price range, keep it simple and safe:

• A verified dealer from the Pesoteca shop directory can value it on the spot.
• The Pesoteca buy-and-sell forum connects you directly with collectors.
• Photograph the obverse, reverse, and edge before you sell, and compare against the range on this page.

Because it is a precious-metal coin, only deal with buyers who let you verify weight and see the piece first. Avoid dumping it to the first bidder on social media, and be cautious on open marketplaces where counterfeits are most common.

1/20 troy ounce Silver Libertad 1994 Regular BU

This piece is the 1/20 troy ounce Silver Libertad, struck by the Mexican Mint in 1994 in its Regular BU version.

Technical specs. 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, chosen 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, alongside other historical coats of arms as the family's identity mark.

Role within the set. It is the smallest fraction of the set. It serves as an introductory piece, a gift, or 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.

Year context. In 1994 Carlos Salinas governed until November and Ernesto Zedillo from December 1. It was the year of the Zapatista uprising, the assassination of Luis Donaldo Colosio, and the December Error that collapsed the peso.

Regular BU finish. The Regular finish, cataloged by Banxico as satin or BU, is obtained with dies without special polishing. The result is an even matte luster across the entire surface, without a mirror contrast between fields and relief. It is the traditional bullion finish: 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 draining their wallet on each piece.

Mintage. The exact mintage of this combination does not appear in the Bank of Mexico's public 2000–2025 tables. For pieces outside that range, the specific Mint catalog must be consulted.
