100 Pesos Benito Juárez Bicentenary 2006: Value Guide

If you inherited or found a Mexican 100 Pesos coin marking the Bicentennial of Benito Juárez's birth (dated 2006), here is the honest answer: in most grades this is a low-value commemorative, typically worth a few dollars over face value. The pieces that bring more are certified high grades and examples kept in the original Banxico packaging. This is not a rare coin worth thousands, and any listing claiming otherwise is inflating it.

What this coin actually is

This is a 100 Pesos commemorative struck in a single year, 2006, honoring the 200th anniversary of the birth of Benito Juárez García, one of Mexico's most important presidents. "Bicentenario del Natalicio" translates to "Bicentennial of the Birth."

Key specifications (match yours against these before assuming anything):

• Denomination: 100 Pesos
• Year: 2006 (single-year issue, no other dates)
• Weight: 3.71 grams
• Diameter: 21 mm
• Composition: bimetallic (two-metal, ring and center)
• Edge: interrupted reeded edge
• Era: Nuevos Pesos / modern issues

One thing to clear up right away: at 3.71 grams this coin does not contain meaningful silver or gold, so there is no bullion floor propping up its value. Mexico did issue silver 100 Pesos commemoratives in other series, and those are worth real money for their metal. This small bimetallic version is not one of them. If someone told you it is silver, weigh it. A silver 100 Pesos would be far heavier.

What it's worth in 2026

Value on this issue tracks condition and packaging, not age. Here is a realistic breakdown.

Condition	What it means	Approximate value (USD)
Circulated	Handled, minor wear	5 to 10
Uncirculated (raw)	No wear, loose	8 to 20
Original Banxico packaging	Sealed blister/set	15 to 35
Certified high grade (NGC/PCGS MS-67+)	Graded, top-condition	40 to 100+

These are collector ranges, not guaranteed sale prices. A common circulated example changing hands between collectors sits at the low end. The premium comes almost entirely from certified top grades or intact original mint packaging, and even then this stays a modest coin.

The exact mintage of this issue is not officially published by Banco de México (Banxico). When the mint does not release a figure, it usually means the coin came out in restricted numismatic sets or a very targeted release. Collector forums float numbers, but none are confirmed, so treat any "only X ever made" claim with skepticism.

The myth to ignore

A modern commemorative dated 2006 is not old, and being old would not make it valuable anyway. What drives coin value is genuine rarity (low surviving population), collector demand, certified grade, and precious-metal content. This coin scores low on all four. It is a nice piece to keep if Juárez means something to you, but it is not a retirement fund. If you see it listed for hundreds of dollars in ordinary condition, that is an asking price, not a selling price.

How to tell if yours is genuine

Counterfeits of a coin this modest are uncommon, but here is the fast check:

1. Weigh it. It should be 3.71 grams. Off by more than a fraction and something is wrong.
2. Measure it. 21 mm diameter.
3. Check the relief. Compare the detail against official Banxico images. Fakes tend to have flatter, mushy relief.
4. Inspect the edge. It should show the interrupted reeded pattern.

For a coin in this value range, professional grading is rarely worth the fee. Save certification (NGC or PCGS) for genuinely valuable pieces. Use our coin grading guide to judge condition yourself before you sell.

Errors that can raise the value

Genuine mint errors (off-center strikes, die rotation, double strikes) can multiply the value of any coin, this one included. The catch: most "errors" people post online are post-mint damage such as dings, scratches, or corrosion, not factory errors. If you think you have a real one, photograph it clearly and post it to the Pesoteca forum so experienced collectors can weigh in before you get your hopes up.

Where to sell it

Since this is a low-value modern coin, keep it simple:

• Collector forums and marketplaces like the Pesoteca buy-sell forum, where you deal with people who actually want this issue.
• A verified numismatic shop from the Pesoteca shop directory, which will appraise it on the spot with no middleman markup.
• Online marketplaces can work, but that is also where most fakes circulate, so always ask the seller (or provide, if you're selling) clear photos of both faces and the edge, plus the weight.

Before you sell, photograph the front, back, and edge, and check the ranges above so you don't undersell or overprice. Don't dump it to the first offer on social media.
