How much is the 100 Pesos 470th Anniversary of the Mexican Mint (2005): Value Guide worth?
The market value of the 100 Pesos 470th Anniversary of the Mexican Mint (2005): Value Guide is not yet documented with enough data to give a firm range. Weigh and measure your piece, compare it against the specifications, and check the forum for a second opinion.
The real price depends on four factors: the grade of preservation (a circulated piece is worth the low end of the range; an uncirculated one, or one still in its official blister pack, the high end), the finish (satin vs mirror/proof), the rarity within the series based on the mintage, and the metal spot price on the day of the deal when the piece is silver or gold. Check the value-by-grade table above and compare with equivalent pieces before buying or selling.

Description
If you inherited or found a 100 Pesos 470th Anniversary of the Mexican Mint (2005) coin, here is the honest answer: this is not a rare classic worth thousands. It is a modern commemorative with a real silver core, so it has a value floor tied to metal content, and a modest premium above that if the condition is high. Most examples trade in the low tens of US dollars, not hundreds.
What this coin actually is
This is a 100 Pesos coin struck in 2005 to mark the 470th anniversary of the Casa de Moneda de México (the Mexican Mint), the oldest mint in the Americas. The "100 pesos" is the face value in Mexican pesos, not US dollars. At current exchange rates 100 pesos is roughly 5 to 6 US dollars, but the coin is worth more than face because of what it is made of.
It is a bimetallic coin: a silver center ring surrounded by a base-metal outer ring. That silver center is why the coin has a real floor value. Do not spend it as pocket change.
Specifications (keep these exact)
| Spec | Detail |
|---|---|
| Face value | 100 Pesos |
| Year | 2005 (single year of issue) |
| Weight | 33.9 grams |
| Diameter | 39 mm |
| Composition | Bimetallic (silver center, base-metal ring) |
| Edge | Discontinuous reeded |
| Reverse theme | 470th Anniversary of the Casa de Moneda de México |
The silver center on this series carries roughly 20 grams of .999 fine silver, which works out to about 0.64 troy ounces. At a silver price near 30 US dollars per ounce, that is close to 19 to 20 US dollars in melt value alone. That number moves with the silver market, so check the spot price the day you value it.
What it is worth in USD
Because the silver content sets a floor, this coin rarely sells for less than its melt value. Above that, condition and packaging drive the premium.
| Condition | Realistic value (USD) |
|---|---|
| Circulated, no packaging | 20 to 30 |
| Uncirculated, loose | 30 to 45 |
| Uncirculated in original Banxico blister | 45 to 70 |
| Certified high grade (NGC/PCGS MS-67+) | 70 to 150+ |
These are ranges, not fixed prices. A certified example in top grade can push toward the higher end because collectors of the full mint-anniversary series will pay for eye appeal and a slabbed grade. A worn, scratched piece is worth its silver and little more.
The original Banxico blister pack (the sealed plastic holder it was sold in) matters. A coin still sealed in intact packaging commands a premium over a loose example in the same condition.
Is it rare?
No confirmed mintage figure was published by Banxico for this specific issue, which usually points to a limited numismatic release rather than a mass circulation strike. Low or undocumented mintage sounds exciting, but it does not automatically make a coin valuable. Value needs both scarcity and demand. This series has a steady collector base, not a frenzied one, so prices stay reasonable. Treat any "worth thousands" claim online with skepticism unless it is a certified top-pop example.
How to tell if yours is genuine
Start with the physical checks, because counterfeits usually fail them:
- Weight: it must be 33.9 grams. Use a jewelry scale. A significant deviation is a red flag.
- Diameter: 39 mm. Measure with calipers.
- Relief and detail: compare against official Banxico images. Fakes tend to have flat, mushy detail and soft lettering.
- Bimetal seam: the join between the silver center and the outer ring should be clean and tight.
- Edge: discontinuous reeding, not a smooth or crudely cut edge.
For a coin you plan to sell above the low end, professional certification from NGC or PCGS is the definitive answer on both authenticity and grade. The certification cost is worth it only if the coin is likely to grade high.
Where to sell it
Your best options, ranked by safety:
- A verified numismatic dealer who can appraise it on the spot and pay fairly. Browse the Pesoteca shop directory to find one.
- Collector-to-collector through the Pesoteca buy-and-sell forum, where buyers know exactly what this coin is.
- Online marketplaces, which can bring good prices but attract the most fakes. If you sell there, post clear photos of the obverse, reverse, and edge, and state the weight.
Before you sell, photograph all three sides, confirm the weight, and check the current silver spot price so you never accept less than melt value. Do not dump it on the first lowball offer.
To confirm the exact condition of your piece, run through our coin grading guide first. If you think you have a minting error or an unusual variety, post photos in the Pesoteca forum and let the community weigh in before you assume it is worth a premium.

Frequently asked questions
How much is the 2005 100 Pesos 470th Anniversary coin worth?
Most examples sell for 20 to 45 US dollars, driven mainly by the silver in the center ring (about 0.64 troy ounces, a floor of roughly 19 to 20 dollars at current spot). Uncirculated coins in the original Banxico blister can reach 45 to 70 dollars, and a certified top-grade piece can exceed 100 dollars. The 100 pesos face value is Mexican pesos, not dollars, so the coin is always worth more than face.
Is the 2005 100 Pesos Mexican Mint anniversary coin rare?
Banxico did not publish a confirmed mintage for this issue, which points to a limited numismatic release rather than mass circulation. That said, scarcity alone does not make it valuable. Demand for this series is steady but not extreme, so prices stay modest. A certified high-grade example is the version that carries a real premium.
Where can I sell my 2005 100 Pesos anniversary coin?
The safest routes are a verified dealer from the Pesoteca shop directory, who can value it on the spot, or the Pesoteca buy-and-sell forum where collectors know the coin. Online marketplaces work but attract fakes, so post photos of the obverse, reverse, and edge plus the weight. Always check the silver spot price first so you never sell below melt value.
How do I tell if my coin is genuine?
It must weigh 33.9 grams and measure 39 mm; verify both with a scale and calipers. Compare the relief to official Banxico images, since fakes look flat and soft. Check that the bimetal seam is tight and the edge shows discontinuous reeding. For a coin you plan to sell above the low end, NGC or PCGS certification is the definitive proof of authenticity and grade.
