2 oz Silver Libertad 2017 Proof

If you have a 2017 2-ounce Silver Libertad in proof finish, you own one of the scarcest silver pieces Mexico struck that year: just 3,050 coins were made. That low mintage, not age, is what drives its value. A clean proof example trades well above its silver melt value, while a mishandled one drops toward bullion price.

The Onza Libertad ("Liberty Ounce") is Mexico's flagship silver coin, struck by the Casa de Moneda de México (the national mint) and backed by Banxico, the central bank. This particular piece is the 2-ounce proof version: larger than the standard one-ounce Libertad, but smaller than the 5-ounce and kilo formats.

What it's made of

This is a real silver coin, not a token. Here are the exact specs:

Spec	Detail
Metal	Silver .999 fine
Weight	62.2 grams (2 troy ounces)
Diameter	48 mm
Edge	Reeded
Finish	Proof (mirror field, frosted relief)
Mintage	3,050 pieces
Design	Winged Angel of Independence over the Valley of Mexico, with volcanoes; National Coat of Arms on reverse

The proof finish is what sets it apart visually: the background is a bright mirror, and the raised design is matte-frosted, so the Angel of Independence and the national eagle stand out crisply against the shine. Any fingerprint or scratch on that mirror field is easy to spot and hurts the price.

What it's worth

Two things set the floor and the ceiling on this coin:

1. Metal floor. With 2 troy ounces of .999 silver, the coin can never be worth less than 2 times the daily silver spot price. That's the bullion baseline.
2. Rarity premium. At only 3,050 pieces, this is a genuinely scarce modern issue. In a Libertad set, the 2-ounce proofs are usually among the last to complete, precisely because so few exist.

A proof in original, untouched condition (no handling marks, clean mirror field) commands a solid premium over melt. A coin with fingerprints, hairlines, or spotting slides back toward its silver value. Because the market for modern silver proofs moves with both the collector demand and the silver spot price, check the current spot before you buy or sell so you know your baseline.

Condition is everything with proofs. The difference between an untouched piece and a mishandled one can be significant, which is why serious buyers want to see the coin in hand or in high-resolution photos of both sides and the edge.

Is it actually rare?

Yes, by modern standards. A mintage of 3,050 is low for a bullion-derived series, and the 2-ounce proofs are collected specifically for that scarcity. That said, "rare" and "worth millions" are not the same thing. This is a scarce modern collectible with a real silver value underneath, not a six-figure trophy coin. Anyone telling you a modern Libertad is worth a fortune because it's "old" is wrong: it isn't old, and its value rests on mintage plus condition plus metal.

How to check if yours is genuine

Because this is a precious-metal coin, fakes exist. Two quick, at-home checks catch most of them:

• Weigh it. Use a jeweler's scale. It should read 62.2 grams. Fakes are often off on weight.
• Measure the diameter. Use calipers. It should be 48 mm.

Beyond the numbers, look at the strike: genuine proofs have sharp, frosted relief against a clean mirror. Flat detail, dull surfaces, or uneven finish are red flags. And treat any offer far below the silver value as a warning sign, not a bargain.

For a definitive answer, a graded coin from NGC or PCGS removes the guesswork, since the piece is authenticated and sealed. If you're buying an ungraded coin, buy only from someone who will show you the piece and its weight before you pay.

Where to sell it (or buy one)

To sell, your safest options are a verified numismatic shop from the Pesoteca directory, which can appraise it on the spot, or the Pesoteca buy-and-sell forum, where you deal directly with collectors. Photograph the coin (obverse, reverse, and edge) and compare notes with this page before you commit. Avoid dumping it on social media to the first bidder.

Buying works the same way: stick to a verified shop or the collector forum, and only pay after you've confirmed the coin and its weight. If you're building out a full Libertad set, the 2-ounce proofs are worth chasing early, since they get harder to find over time.

Think you might have a striking error or a variant on your example? Post clear photos in the Pesoteca forum and let the community weigh in before you assume it's worth more.

2 troy oz Libertad silver 2017 Proof

This piece is the 2 troy oz silver Libertad, minted by the Mexican Mint in 2017 in its Proof version.

Technical data. It contains 62.2 g of pure silver, .999 fineness, and measures 48 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 the family's mark of identity.

Role within the set. It is a piece for serious collecting. Its mintage is far lower than that of the standard ounce, and its large format lets the detail of the engraving shine. It is usually pursued as a pair with the 5 oz coin.

Context of the year. In 2017 Enrique Peña Nieto was in office. The September 19 earthquake struck Mexico City again. Silver closed at 16.87 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 leaves the press ready for display: it is not touched in the open 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 that of the same year's regular finish, and its price on the secondary market usually runs between 40% and 80% above the equivalent BU version.

Mintage. Banxico reported in its official tables a mintage of 3,934 pieces for this combination of fraction, year and finish. That number is the basis for gauging the piece's relative scarcity within the program.
