How much is the coin Chichén Itzá Silver Ounce (Casa de las Monjas): Value & How to Sell worth?
The market value of the coin Chichén Itzá Silver Ounce (Casa de las Monjas): Value & How to Sell 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 Mexican silver round showing a Mayan temple and the words "Casa de las Monjas," here is the short answer: it is a one-ounce coin struck in .999 fine silver, so it is worth money. The floor is the current silver spot price for one troy ounce, and a clean, uncirculated example in demand can bring a modest premium above that. This is not a rare six-figure coin. It is a solid silver piece with a real, verifiable value.
What you actually have
The Chichén Itzá "Casa de las Monjas" ounce is struck in .999 fine silver and measures 40 mm in diameter, the standard format the Mexican Mint (Casa de Moneda de México) uses for its pure-silver pieces. The design honors the Casa de las Monjas ("House of the Nuns"), one of the most recognizable structures at Chichén Itzá, the Mayan archaeological site in northern Yucatán. The relief reproduces the carved stone facade that makes the building distinctive.
Because it is one troy ounce of pure silver, your coin has a hard floor: it can never be worth less than the metal it contains. That is the single most important fact for anyone who just wants to know "is this worth anything." Yes, it is, and you can look up the number today.
How much is it worth in 2026?
Value rests on two things: silver content and condition. Here is how to think about it.
| Factor | What it means for your coin |
|---|---|
| Metal | 1 troy oz of .999 silver = melt value at current spot |
| Melt floor | Whatever one ounce of silver trades for the day you sell |
| Premium | A small markup over melt for a clean, collectible piece |
| Condition | Original mint luster and no rubbing on the high points hold value best |
| Certified grade | NGC or PCGS slabbed examples sell for more than raw coins |
A quick way to estimate: check today's silver spot price for one ounce, and that is your baseline. A worn or scratched example sells at or near melt. A bright, uncirculated coin with full detail carries a premium above melt, and a professionally graded high-grade example can carry more. This is a bullion-and-collector piece, not a rarity that commands thousands. Anyone quoting you a huge number without a certified grade is guessing.
The exact mintage for this issue is not officially documented by the Mexican Mint. When mintage is unpublished, it usually means the piece came out in a limited numismatic set or a small, specific run. Collectors speculate on figures in forums, but none are confirmed, so do not price your coin off an unverified "only X were made" claim.
The myth: "an old Mexican silver coin must be worth a fortune"
Most silver rounds like this one are worth their metal plus a modest premium, period. The pieces that break auction records are older, genuinely scarce coins with documented low survival, not modern .999 bullion honoring a tourist site. If you want to see what real four- and five-figure Mexican coins look like, those are a different category entirely. Your Casa de las Monjas ounce is a nice, tangible piece of silver with a cultural design, and it holds its value because of the metal, not because it is rare.
How to tell if yours is genuine
The good news: fakes on precious-metal pieces are easy to catch with two measurements.
- Weigh it. It should weigh one troy ounce (about 31.1 grams). Underweight is a red flag.
- Measure the diameter. It should be 40 mm. Off-size means trouble.
- Check the relief detail against official Mexican Mint images. Genuine strikes are crisp; casts and copies look soft or grainy.
- Inspect the edge. Ask any seller for a photo of the edge and the coin on a scale before you buy.
If you are spending more than a couple hundred dollars, or you suspect something is off, have it authenticated by a recognized dealer or send it to NGC or PCGS for grading and certification. A certified coin is easier to sell and always brings more.
Where to sell it
Because it is a precious-metal coin, you will always find a buyer. Your best options:
- A verified numismatic shop from the Pesoteca dealer directory, which values the coin on the spot.
- The Pesoteca buy-and-sell forum, where collectors trade directly.
- Any established coin dealer who will quote you a price over melt.
Before you sell, photograph the obverse, reverse, and edge, and check the current silver spot price so you know your floor. Do not dump it to the first offer on social media. If a buyer will not show you the coin and its weight, walk away.
Errors and varieties
Genuine mint errors (off-center strikes, die rotation, double strikes) can raise the value of any coin. Most "errors" people post online are post-mint damage: dings, corrosion, and scratches, not factory mistakes. If you think you have a real one, post clear photos on the Pesoteca forum so the community can weigh in before you assume it is worth extra.
