1/4 oz Gold Libertad 2009 Proof

If you inherited a small gold Mexican coin with an angel on one side and a golden eagle on the other, and it came in a plastic capsule with a mirror-like shine, you may have a 1/4 oz Gold Libertad Proof. The 2009 Proof is worth more than melt value because only 1,700 were struck, but it is not a lottery ticket: figure a floor at the gold price for a quarter ounce, plus a collector premium for the low mintage and Proof finish.

What it's worth in 2026

This coin has two prices, and you need to understand both.

The floor (melt value): The coin contains exactly a quarter of a troy ounce of pure gold (.999 fine). Whatever a quarter ounce of gold trades for on any given day is the absolute minimum this coin is worth. With gold prices where they've been recently, that floor alone runs several hundred USD. It never goes below that.

The collector premium: Because this is the Proof version (special mirror-finish strike) with a mintage of just 1,700 pieces, it commands a premium over melt. A clean, capsule-fresh 2009 Proof typically trades at a meaningful markup above the gold value, more than a plain bullion 1/4 oz Libertad of the same year. Condition drives the premium hard: a flawless piece still in its original capsule sells for well more than one with hairlines, fingerprints, or handling marks in the mirrored fields.

We are giving you a range rather than one exact number because gold moves daily. To price yours today, check the current spot price of gold, divide by four for the quarter ounce, and add the Proof/low-mintage premium.

What you actually have

The Libertad is Mexico's flagship bullion series, issued by Banco de México (Banxico) and struck at the Mexican Mint (Casa de Moneda de México). Here are the exact specs, which matter for spotting a fake:

• Metal: Gold, .999 fine (99.9% pure)
• Weight: 7.77 grams (1/4 troy ounce)
• Diameter: 23 mm
• Edge: Reeded
• Finish: Proof (mirror fields, frosted relief)
• Mintage: 1,700 pieces

The front (obverse) shows the Winged Victory statue known as the Ángel de la Independencia, with the Popocatépetl and Iztaccíhuatl volcanoes behind her. The back (reverse) carries the Mexican coat of arms surrounded by the historical versions of the national shield. The quarter-ounce is one of the more affordable gold sizes in the series, and the Proof version turns it from a pure investment piece into something aimed at collectors.

Why the Proof matters

A "Proof" coin is not a different design. It is a different way of striking the same coin: polished dies and specially prepared blanks produce mirror-like backgrounds and a frosted, matte relief. Proof coins are made for collectors, not for stacking bullion, so they are produced in far smaller numbers. That is why the 2009 Proof, at 1,700 pieces, sits among the shorter runs in the modern gold Libertad family and carries a premium a standard bullion strike does not.

The catch most people miss

Condition is everything on a Proof. The value lives in those flawless mirror fields. A single wipe with a cloth, a fingerprint, or being tumbled loose in a drawer can knock the coin down toward plain bullion value. If yours is still sealed in its original capsule with no marks, that is the best case. If it has been handled, cleaned, or shows hairlines, expect a lower premium. Do not clean it. Cleaning a gold Proof almost always lowers its value.

How to check what yours is worth

1. Confirm the specs. Weigh it on a jewelry scale (should be 7.77 g) and measure the diameter (23 mm) with calipers. Off weight or off diameter is a red flag for a fake.
2. Grade the condition. Look at the mirrored fields under good light. Hairlines, spots, or fingerprints lower the grade. For a definitive answer, third-party grading (NGC or PCGS) gives an official grade and confirms authenticity.
3. Price the gold first. Get the current gold spot price, take a quarter of it, and treat that as your floor.
4. Add the premium. Compare recent sales of the 2009 Proof to gauge the markup over melt.

Where to sell it

Because this is a precious-metal coin, sell where the buyer will handle it in front of you and verify the weight before money changes hands. Your safest options are a verified coin dealer from the Pesoteca shop directory, who can appraise it on the spot, or the Pesoteca buy/sell forum among collectors. Photograph the obverse, reverse, and edge, and confirm the price range above before you sell. Avoid dumping it to the first offer on social media.

This piece is a 1/4 oz gold Onza Libertad struck in 2009 in Proof finish. The series was created by the DOF decree of April 8, 1981, and added the 1/2, 1/4, 1/10, and 1/20 fractions from 1991.

Felipe Calderón. The year of the H1N1 pandemic in Mexico and of a gold rebound. Spot closed at 1,087 dollars per ounce and the FIX at 13.06 pesos.

Fraction: pure gold 7.776 grams, 0.999 fineness, total weight 8.64 grams, diameter 27 millimeters. The quarter ounce is the intermediate piece most hunted by those building a complete set of fractions. Premium over spot 8 to 15 percent, the mid tier of the family.

Proof: frosted mirror fields over matte relief, polished dies and multiple strikes. It ships encapsulated with an individual certificate. The Proof mintage is always a fraction of the regular one, typically +40 to 100 percent over bullion.

Banxico CM10 (consulted 2026-05-27) records 350 pieces against 1,541 pieces in the regular version of the same year. The differential explains the premium between variants.

The Proof is hunted for the complete set of fractions and for the certificate with original capsule. When buying peer-to-peer, check the capsule for scratches, the certificate tied to the piece, and compare the premium against the regular of the same year before dealing with a middleman.
