1/20 oz Gold Libertad 2006

The 1/20 oz Gold Libertad 2006 is worth at least its gold content, roughly 130 to 150 USD as bullion in 2026, and often more because Mexico's mint struck only 1,278 of them that year. That tiny mintage is what separates this coin from ordinary gold rounds. If you inherited one, do not sell it for melt without checking the grade first.

What you actually have

The Libertad ("Liberty") is Mexico's official bullion series, minted by the Casa de Moneda de México, the oldest mint in the Americas. The 1/20 oz version is the smallest gold size in the line. Here are the hard specs, which matter for both value and spotting fakes:

• Metal: pure gold, .999 fine
• Weight: 1.5552 grams (one twentieth of a troy ounce)
• Diameter: 13 mm
• Edge: reeded (grooved)
• Finish: satin
• Year: 2006 only

The obverse shows Mexico's national coat of arms surrounded by historic eagles and elements from the Códice Mendocino. The reverse carries the Ángel de la Independencia (the Angel of Independence, Mexico City's famous gold-winged monument) with the volcanoes Popocatépetl and Iztaccíhuatl behind it. This design belongs to the modern series Mexico's central bank, Banxico, calls the "Nueva Serie Libertad," established by decree in 1999.

How much is it worth

There are two ways to value this coin, and you need to know both.

1. As gold (the floor). At 1.5552 grams of .999 gold, the metal alone is worth roughly 130 to 150 USD, moving with the gold spot price. No Libertad ever trades below this floor. That is the safety net every bullion coin gives you.

2. As a collectible (the upside). This is where 2006 gets interesting. Banxico reports an official mintage of just 1,278 pieces for the 2006 satin finish. For context, common years of larger gold Libertades run into the tens of thousands. A mintage under 1,300 puts this coin in genuinely scarce territory, and low-mintage gold Libertades regularly sell above melt to collectors who want a complete date set.

Coin	Year	Mintage	Approx. value (ungraded)	Approx. value (high-grade certified)
1/20 oz Gold Libertad	2006	1,278	150 to 250 USD	300 USD and up

The exact premium depends on condition and how badly a buyer needs the 2006 date. A coin still in its original mint packaging, or one graded MS69/MS70 by NGC or PCGS, commands the top of the range. A loose, handled coin sits closer to the gold floor.

The myth: "it's tiny gold, it can't be worth much"

Size does not drive value here. The 1/20 oz is the smallest gold Libertad, but the 2006 mintage of 1,278 makes it one of the tougher dates to find in the whole series. Do not judge it by weight. A collector building a date-run cares about the year on the coin, not how many grams it holds.

How to tell if yours is genuine

Gold fakes almost always fail on the physics. Check these before anything else:

• Weight must be 1.5552 g. Counterfeits from overseas typically use lower-purity alloy and come out under or over weight. A jeweler's scale settles it.
• Diameter must be 13 mm.
• The edge must be reeded, evenly and cleanly.
• A gold coin does not stick to a magnet. If it does, it is not gold.

If the specs check out and the coin is worth a meaningful premium, send it to NGC or PCGS for certified grading. Certification confirms authenticity and locks in the grade, which is the single biggest driver of collector value.

Where to sell it

For a coin like this, your best options are:

• A verified numismatic dealer from the Pesoteca directory, who can appraise it on the spot and pay a fair premium over melt.
• The Pesoteca buy-and-sell forum, where collectors who actually want the 2006 date will pay for it.
• A precious-metals buyer, but only if you just want the gold value. You will leave the scarcity premium on the table.

Before you sell, photograph the obverse, reverse, and edge, and confirm the weight. Because this is a precious-metal piece, only deal with a buyer who lets you verify the coin before money changes hands. Do not dump it to the first offer on social media.

This piece is a 1/20 ounce gold Libertad minted in 2006 in a regular finish (bullion satin). The series was born by DOF decree of April 8, 1981, and added the 1/2, 1/4, 1/10, and 1/20 fractions from 1991.

The close of Fox's term and the transition to Felipe Calderon (PAN). Average gold spot 604 dollars per ounce and FIX close of 10.88 pesos.

Fraction: pure gold 1.555 grams at 0.999 fineness, total weight 1.73 grams, diameter 20 millimeters. The 1/20 is the smallest fraction and the gateway to physical gold. It began to be minted in 1991. Premium over spot of 15 to 25 percent, the highest in the family.

Regular (bullion satin): matte-luster fields and satin relief, a single press strike. Wholesale distribution for physical gold investment, the largest mintage of the year and the natural reference for premium against spot.

Banxico CM10 (consulted 2026-05-27) records 1,278 pieces against 481 pieces in the Proof version of the same year. The differential explains the price gap between variants.

The regular is bought for its gold content with a low premium over spot. Verify weight, diameter, and reeded edge; compare the premium against Banxico Direct before accepting a middleman.
