1/20 oz Silver Libertad 2017: Value & Real Prices

If you inherited or found a 2017 1/20 oz Silver Libertad, here is the honest answer: this is not a melt-value coin. With an official mintage of just 8,550 pieces, it is one of the scarcest fractional Libertads Mexico issued, and collector demand pushes it well past the value of its tiny silver content. Depending on condition and packaging, expect roughly 30 to 80 USD, with pristine examples reaching more.

That premium is the whole story here. The coin holds only 1.5552 grams of silver, worth about 1.50 to 2 USD as metal. Nobody pays 40 or 50 USD for the silver. They pay for the low mintage and the fact that fractional Libertads are hard to complete as a set.

What this coin actually is

The Libertad ("Liberty") is Mexico's flagship bullion and collector series, struck by Banco de México, the country's central bank. The full series runs from a 1-ounce piece down to tiny fractions: 1/2, 1/4, 1/10, and 1/20 ounce. The 1/20 oz is the smallest silver Libertad, and because so few are made each year, the fractions are the ones collectors chase.

Specifications for the 2017 1/20 oz Silver Libertad, straight from Banco de México:

• Metal: .999 fine silver (99.9% pure)
• Weight: 1.5552 grams (1/20 of a troy ounce)
• Diameter: 16 mm
• Edge: reeded
• Finish: bullion (satin), the investment version with a uniform matte surface
• Official mintage: 8,550 pieces
• Mint mark: "Mo" (Mexico City mint)

The obverse shows the Mexican National Coat of Arms, an eagle perched on a cactus devouring a serpent, with the legend "ESTADOS UNIDOS MEXICANOS." The reverse features the Winged Victory (the "Ángel de la Independencia" statue in Mexico City) standing before the Popocatépetl and Iztaccíhuatl volcanoes, with the year 2017.

Why 8,550 matters

Mintage is the single biggest driver of value on this coin. To put 8,550 in perspective, some 1-ounce Libertads are struck in the hundreds of thousands. When only a few thousand of a coin exist worldwide, collectors trying to build a complete fractional set have to compete for them, and prices climb.

This is where the honest caveat comes in. A low mintage helps only if the coin is in good condition and, ideally, still in its original mint packaging or certified. A worn, scratched, or cleaned example loses most of its premium.

What it's worth by condition

Coin	Year	Condition	Typical value (USD)
1/20 oz Silver Libertad	2017	Circulated / handled	25 to 40
1/20 oz Silver Libertad	2017	Uncirculated, original packaging	40 to 70
1/20 oz Silver Libertad	2017	Certified high grade (NGC/PCGS MS69-70)	70 to 150+

These are collector ranges based on typical dealer and auction activity for scarce fractional Libertads. The exact figure depends on grade, eye appeal, and whether the buyer needs this specific date to finish a set. If you have a certified MS70 example, list it where serious Libertad collectors look rather than a general marketplace.

The myth to ignore

One recurring claim online is that any silver Libertad is "worth a fortune." It is not. Most common-date, higher-mintage Libertads trade close to their silver content plus a small premium. What makes the 2017 1/20 oz different is the specific 8,550 mintage, not the fact that it says Libertad. Judge every Libertad by its date and mintage, not by the name on the coin.

How to check what yours is worth

1. Confirm it's genuine. Weigh it on a jeweler's scale (should be 1.5552 grams) and measure the diameter (16 mm) with calipers. Counterfeits usually miss the weight, the diameter, or show flat, mushy relief. Be suspicious of any offer far below the coin's known value.
2. Grade the surface. Look under good light for scratches, spots, or signs of cleaning. Handling marks drop the price fast. Do not clean it; cleaning almost always lowers value.
3. Consider certification. For an uncirculated example, grading by NGC or PCGS can confirm authenticity and pin down the grade, which matters most at the high end.
4. Photograph both sides and the edge before you sell, so buyers can judge it accurately.

Where to buy or sell

The safest route is a verified numismatic dealer, who can appraise it on the spot, or a collector-to-collector marketplace where Libertad buyers actually shop. Because this is a precious-metal coin, only deal with sellers who will show you the piece and its weight, and verify before you pay. Avoid dumping it to the first bidder on a general social media group.

1/20 troy ounce Libertad silver 2017 Regular BU

This piece is the silver Libertad coin of 1/20 troy ounce, struck by the Mexican Mint in 2017 in its Regular BU version.

Technical data. 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 series' official symbol since 1981. The obverse features the National Coat of Arms in its pre-1969 version, along with other historical coats of arms as the family's identity mark.

Role within the set. It is the smallest fraction in the set. It serves as a starter piece, gift, or first contact with the series: it costs little per specimen but carries the highest premium in the family over the value of the silver it contains, because the die cost is spread across fewer grams.

Context of the year. In 2017 Enrique Peña Nieto was in office. The earthquake of September 19 struck Mexico City once again. Silver closed at 16.87 USD per troy ounce.

Regular BU finish. The Regular finish, cataloged by Banxico as satin or BU, is achieved with dies without 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: 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 draining their funds on each piece.

Mintage. Banxico reported in its official tables a minting of 12,293 pieces for this combination of fraction, year, and finish. That number is the basis for measuring the piece's relative scarcity within the program.
