100 Pesos Gold Benito Juárez Bicentennial 2006

If you inherited a heavy gold coin with Benito Juárez on it dated 2006, here is the fast answer: it is a real gold coin, and its value floor is the metal itself. At current gold prices that floor sits north of USD 2,000, and a pristine certified example runs higher. This is not a coin worth a few dollars.

Most old coins people find are worth pocket change. This one is the exception, and the reason is simple: it contains just over one troy ounce of gold. That gives it a hard price floor that moves with the gold market, not with sentiment.

What this coin actually is

The 100 Pesos Bicentenario del Natalicio de Benito Juárez (Bicentennial of the Birth of Benito Juárez) is a gold commemorative struck in 2026's reference year of 2006 by the Casa de Moneda de México, Mexico's national mint. It marks 200 years since the birth of Benito Juárez, one of Mexico's most important 19th-century presidents. His portrait sits at the center of the coin.

This was never a coin you would get as change. It was issued as a gold commemorative aimed at collectors and people buying gold to hold value.

The specs that determine its worth

That 33.94 grams at .900 fineness works out to just over one full troy ounce of actual gold. That number is the single most important thing to understand about this coin.

How much is it worth?

Because the coin holds roughly one troy ounce of gold, its value starts at the melt value of that gold and goes up from there. Melt value moves daily with the gold market. As a working reference, one troy ounce of gold has traded well above USD 2,000 in recent years, so the floor for this coin is in that range regardless of grade.

On top of the metal, condition adds a premium:

• Circulated or handled, with visible marks: close to melt value, so roughly the price of one ounce of gold on the day you sell.
• Uncirculated with original luster: melt value plus a modest collector premium.
• Certified high grade (NGC or PCGS MS-65 and up): the strongest premiums over melt, since the mint gold market rewards flawless surfaces.

The practical takeaway: with a gold coin like this, you are mostly selling gold. A dealer who tries to pay you well under the daily melt value is lowballing you.

The myths, cleared up

Coins like this attract two bad assumptions.

First, "it's old and Mexican, so it must be a rare treasure." It is valuable because it is gold, not because it is scarce in the way a rare error or a low-mintage silver piece would be. Its worth tracks the gold market.

Second, "a single year means it's super rare." It was issued only in 2006, but single-year issue does not automatically mean rarity. What matters for the premium is grade and eye appeal, not the calendar.

The mintage figure for this specific issue is not officially published by Banxico, which usually means it came out in limited numismatic sets or as a targeted release. Collector forums float numbers, but none are confirmed, so treat any "only X were made" claim with caution.

How to tell if yours is genuine

With a gold coin, fakes exist, and the checks are physical.

1. Weigh it. A genuine piece weighs 33.94 grams. If yours is meaningfully off, stop there.
2. Measure it. Diameter should be 39 mm.
3. Check the edge. It has an interrupted reeded edge you can feel.
4. Compare the relief to official images from Banxico. Counterfeits tend to show flatter, mushier detail.
5. Get it certified. For a coin holding over USD 2,000 in gold, professional grading by NGC or PCGS is the definitive answer. It confirms authenticity and locks in the grade that sets your premium.

Where to sell it

Since this is a precious-metal coin, sell where the buyer can inspect it and where the price reflects the daily gold market:

• A verified numismatic dealer from the Pesoteca directory can value it on the spot and quote against current gold prices.
• The Pesoteca buy-and-sell forum connects you directly with collectors.
• For any gold piece, always deal with someone who will show or verify weight before money changes hands. Photograph the front, back, and edge, and know the day's gold price before you agree to anything.

Avoid dumping it to the first offer online. A gold coin has a knowable floor, so you have leverage.

Have one of these in an inherited box and not sure what condition it's in? Post clear photos of the front, back, and edge in the Pesoteca forum and get a read from people who handle these coins.

Benito Juarez was born on March 21, 1806, in San Pablo Guelatao, Oaxaca. In 2006 it marked 200 years since his birth. This piece commemorates that milestone. Banxico's quarterly SM report shows 0 pieces in circulation because it was an edition made exclusively for collectors in a commemorative triptych.
