1/20 oz Silver Libertad 2015: Value & Prices

The 1/20 oz Silver Libertad 2015 is a small silver coin, not a jackpot. Its floor is about 3 to 6 dollars in silver content, but its low mintage of 18,400 pieces pushes graded examples to 20 to 60 dollars and up. Here is what actually drives the price in 2026, and how to check yours.

What this coin is

The Onza Libertad ("Liberty Ounce") is Mexico's flagship modern silver series, struck by Banco de México, the country's central bank. The full coin is one troy ounce; this one is the 1/20 ounce fraction, the smallest size in the set.

Key specs, exactly as issued:

• Metal: pure silver, .999 fine
• Weight: 1.5552 grams (1/20 troy ounce)
• Diameter: 16 mm
• Edge: reeded
• Finish: bullion (satin), the investment version with a uniform satin surface
• Official mintage (Banco de México): 18,400 pieces
• Mint mark: "Mo" (Mexico City mint)

The obverse shows the Mexican coat of arms, an eagle on a cactus devouring a serpent, with the legend "ESTADOS UNIDOS MEXICANOS." The reverse features the Winged Victory (the Angel of Independence) with the volcanoes Popocatépetl and Iztaccíhuatl behind her, dated 2015.

What it's actually worth in 2026

Because the coin holds so little silver (about one twentieth of an ounce), the metal value is small: roughly 3 to 6 dollars depending on the silver spot price. That is the floor. Nothing genuine trades below its silver content for long.

Where this coin gets interesting is the mintage. At 18,400 pieces, the 1/20 oz fraction is far scarcer than the standard one-ounce Libertad, which is minted by the hundreds of thousands. Fractional Libertads in low mintages attract collectors who chase complete date-and-size sets, and that demand is what lifts the price above melt.

Coin	Year	Typical condition	Approx. value (USD)
1/20 oz Silver Libertad	2015	Raw, circulated	5 to 12
1/20 oz Silver Libertad	2015	Raw, uncirculated	15 to 30
1/20 oz Silver Libertad	2015	Graded MS-69 / MS-70	40 to 80+

These are collector-market ranges for the bullion (satin) version. Prices move with the silver spot price and with how many graded examples surface. A certified MS-70 (a flawless grade from NGC or PCGS) is where the real premium sits, because most survivors show handling marks from being such a tiny, thin coin.

The myth to ignore

A 2015 date is recent. This is not an antique, and no reputable auction has sold a 2015 fractional Libertad for thousands of dollars. If you see a listing claiming this specific coin is "worth a fortune" because it's silver, that's marketing, not market data. The value comes from low mintage and high grade, not age.

The full-size one-ounce Libertads and older key dates in the series can command real premiums, and the proof and colorized special issues are a separate market. If you want to see how the sizes and finishes differ, our guide to the Onza Libertad silver series breaks it down.

How to check what yours is worth

1. Weigh and measure it. Use a jeweler's scale and a caliper. It should read 1.5552 grams and 16 mm. Off numbers point to a fake or a damaged coin.
2. Grade the surface. Bag marks, scratches, and toning drop the price fast on a coin this small. An unmarked, mirror-clean example is worth several times a scuffed one.
3. Consider certification. For a coin this thin, professional grading (NGC or PCGS) is usually only worth the fee if you believe it's MS-69 or MS-70. Below that, the grading cost eats the premium.

Watch for post-mint damage sold as "errors." Genuine mint errors (off-center strikes, die rotation, doubling) can multiply value, but most "errors" circulating online are just dings and corrosion. If you think you have a real one, post clear photos in the Pesoteca forum and let the community weigh in.

Where to sell it

Sell through a verified dealer in the Pesoteca shop directory, where you get an on-the-spot appraisal, or list it among collectors in the buy-and-sell forum. Photograph the obverse, reverse, and edge, and compare against the ranges above before you accept an offer. Because this is a precious-metal coin, only buy or sell in person when you can see and weigh the piece first.

1/20 troy oz Libertad silver 2015 Regular BU

This piece is the Libertad silver coin of 1/20 troy ounce, struck by the Mexico Mint in 2015 in its Regular BU version.

Technical sheet. 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, 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 identity mark of the family.

Role within the set. It is the smallest fraction of the set. It serves as an entry 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 contained, because the die cost is spread across fewer grams.

Context of the year. In 2015 Enrique Peña Nieto governed. Silver closed at 13.82 USD per troy ounce, one of the lowest prices of the period. A historically good year to build the complete set.

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 shine over the whole surface, with no mirror contrast between fields and reliefs. 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 seek to build the complete set by year without decapitalizing on each piece.

Run. Banxico reported in its official tables a mintage of 17,827 pieces for this combination of fraction, year, and finish. That number is the basis for measuring the piece's relative scarcity within the program.
