1/2 oz Silver Libertad 2007 Proof: Value & Mintage

If you inherited or found a 2007 1/2 oz Silver Libertad in Proof finish, you have one of the scarcer fractional pieces in the whole series. Only 1,500 were struck. In 2026, a certified example in top grade sells well above its silver value, often in the low-to-mid hundreds of dollars, while a raw circulated-looking piece trades closer to its metal content.

What it's worth right now

This coin has two floors. The first is bullion: it contains a half ounce of .999 fine silver, so it can never be worth less than roughly half the current spot price of silver (typically in the 15 to 20 USD range depending on the market). The second, and the one that matters here, is the collector premium driven by the tiny 1,500-piece mintage.

In practice:

• A clean Proof with the mirror field intact, no rubs or fingerprints, sells in the range of roughly 150 to 400 USD to collectors, depending on eye appeal.
• The same coin certified by NGC or PCGS at a top grade (PF69 or PF70) can push higher, since graded population is what buyers pay up for.
• A mishandled example with hairlines or spotting drops toward its silver value, since a damaged Proof loses most of its premium.

Because survivors are few, condition swings the price hard. The difference between a pristine coin and a fingerprinted one is not a few dollars, it is the entire premium.

What the coin actually is

The Libertad is the flagship bullion and collector series of the Casa de Moneda de México, the Mexican Mint. The reverse shows the Winged Victory (the Angel of Independence) standing over the two volcanoes; the obverse carries the Mexican coat of arms, in this era surrounded by a ring of historical national shields. "Onza" simply means ounce, so "1/2 Onza" is the half-ounce denomination.

Proof coins are struck separately from the regular bullion issues, on specially prepared dies and blanks, in short numbered runs. The look is a mirror-bright background against a frosted, matte design. On the half ounce that contrast sits especially well over the Angel figure, which is part of why collectors chase this size.

Why the 2007 Proof is scarce

With only 1,500 struck, this is among the most limited fractional Proof issues in the Libertad line. Banxico issues the fractions (1/20, 1/10, 1/4, 1/2 oz) alongside the full ounce, and the half ounce is often the toughest denomination to complete in a year-by-year or fraction set. Collectors building a run of Proof Libertads or a full fractional set frequently stall right here, which keeps demand steady on the few clean survivors.

The value myth to avoid

A low mintage is not a magic ticket. Some sellers list any old-looking Mexican coin as a fortune, and that is not how this market works. This coin is genuinely scarce, but its ceiling is set by grade and by the number of collectors actively completing the set, not by the calendar. Do not expect thousands of dollars for a mishandled piece just because "only 1,500 exist." The premium lives entirely in condition and certification.

How to check what yours is worth

1. Confirm the metal. Weigh it on a jewelry scale (should read about 19.31 grams) and measure the diameter (33 mm). Off weight or off diameter is a red flag for a fake.
2. Grade the surface. Look at the mirror field under a light. Hairlines, spots, or fingerprints pull the value down fast on a Proof.
3. Consider certification. For a coin this scarce, an NGC or PCGS holder with a PF grade is worth the fee, since graded coins sell for more and sell faster.
4. Get a real quote. Use the Pesoteca verified coin shop directory for an in-person appraisal, or post it in the Pesoteca buy/sell forum to gauge collector demand before you commit.

How to tell if it's genuine

Start with weight and diameter against the table above. Counterfeits commonly miss on one or both, or show flat, mushy relief where a real Proof is crisp. The mirror field on a genuine Proof is deep and even; a fake often looks dull or has uneven frosting. Be suspicious of any offer priced well below the silver value, since no honest seller gives away the metal. If anything looks off, photograph the obverse, reverse, and edge and let the community check it in the Pesoteca forum.

Where to sell it

The safest route is a verified numismatic shop from the Pesoteca directory, where you get an on-the-spot valuation, or the collector buy/sell forum, where set builders pay the real premium. Photograph all three surfaces and check the price range on this page before you accept an offer. Avoid dumping a scarce Proof to the first buyer on social media.

1/2 troy ounce silver Libertad 2007 Proof

This piece is the silver Libertad of 1/2 troy ounce, struck by the Mexico City Mint in 2007 in its Proof version.

Technical sheet. It contains 15.55 g of pure silver, .999 fineness, and measures 33 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, along with other historical coats of arms as the family's mark of identity.

Role within the set. It is the upper intermediate fraction. It weighs exactly half the flagship piece and is usually struck in smaller mintages than the full ounce, which gives it a profile of relative scarcity within the year's set.

Context of the year. In 2007 Felipe Calderón Hinojosa was in office. The first full year of Calderón's government. Silver continued its upward trend on the way to 13.38 USD per troy ounce on average.

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-sandblasting. The piece comes off the press ready to display: it is not touched in 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 regular finish of the same year, and its price on the secondary market is usually between 40% and 80% above the equivalent BU version.

Mintage. Banxico reported in its official tables a mintage of 2,043 pieces for this combination of fraction, year, and finish. That number is the basis for measuring the piece's relative scarcity within the program.
