1/20 oz Gold Libertad 2007

If you inherited or found a 1/20 oz Gold Libertad from 2007, here is the honest answer: it is worth real money, and mostly for one reason. Only 728 pieces were struck. That low mintage puts it above a plain bullion coin. This is not a common date you dump at melt.

Most small gold coins are worth their metal content plus a small premium. The 2007 Libertad in this fraction is different because of the numbers. With an official mintage of 728 coins in satin finish, it sits in collector territory, not just bullion territory.

What the coin actually is

The Libertad is Mexico's official bullion series, minted by the Casa de Moneda de México (the Mexican Mint). "Onza" means ounce, and this is the smallest gold fraction: 1/20 of a troy ounce. The design has been in use since a 1999 decree that Banxico (the Bank of Mexico) calls the "Nueva Serie Libertad."

The reverse shows the Winged Victory (Ángel de la Independencia) with the Popocatépetl and Iztaccíhuatl volcanoes behind her. The obverse carries the Mexican national coat of arms surrounded by historic eagle figures drawn from the Códice Mendocino.

Exact specifications, keep these numbers, they are how you verify a real one:

• Metal: .999 fine gold (pure gold)
• Weight: 1.5552 grams
• Diameter: 13 mm
• Edge: reeded
• Finish: satin
• Mintage (2007): 728 coins

What it is worth

The value has two floors. First, the gold itself. At 1.5552 grams of pure gold, the melt value tracks the international gold spot price, so it never falls to zero. Second, the collector premium, which for this coin is the real story because of the 728-piece mintage.

A circulated or lightly handled example trades above melt, but the sharp premium shows up in certified high grades. Because official documentation is thin on how many survive in top condition, we give an honest range rather than a fake exact figure:

Condition	What it means	Typical value (USD)
Raw, handled	Marks, no certification	Gold melt plus a modest premium
Uncirculated, raw	Clean, no wear, not graded	Melt plus a meaningful collector premium
Certified MS-65 or higher	Graded by NGC or PCGS	Several times melt, driven by the 728 mintage

The takeaway: with a mintage this low, certification is what unlocks the premium. An ungraded coin sells near its gold value plus a bump. A high-grade slab from NGC or PCGS is where the low mintage pays off.

How to tell if yours is genuine

Gold fakes almost always fail on weight and size, because counterfeiters cut the gold content. Your first two checks are free:

1. Weigh it. A real coin is 1.5552 grams. If it reads noticeably off, walk away.
2. Measure it. Diameter is exactly 13 mm with a reeded edge.

Most fakes of Mexican gold come in lower fineness and get exposed by weight alone. For a coin carrying a collector premium like this one, the definitive protection is third-party grading from NGC or PCGS. A certified slab confirms authenticity, grade, and locks in the value.

This piece is a gold Libertad Onza 1/20 ounce struck in 2007 in a regular finish (bullion satin). The series was born by decree in the DOF of April 8, 1981, and added the 1/2, 1/4, 1/10 and 1/20 fractions from 1991.

Felipe Calderón (2006-2012). The start of the subprime crisis in the US. Gold spot averaged 695 dollars per ounce and the FIX closed at 10.87 pesos.

Fraction: pure gold 1.555 grams, 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 struck in 1991. Premium over spot 15 to 25 percent, the highest of the family.

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

Banxico CM10 (consulted 2026-05-27) records 728 pieces against 275 pieces in the Proof version of the same year. The gap explains the price difference 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.
