En resumen
Inheriting Mexican coins is easy. Selling them without getting lowballed is the hard part. A few channels pay fair value, others take half, and one that almost nobody uses pays the best.
If you inherited a box of Mexican gold or silver coins, here is the honest answer before you sell: the first buyer almost never pays what the coins are actually worth. There is no single price and no regulated market. The gap between the best and worst offer on the same coin routinely runs 20 to 40 percent. Comparing offers before you sell is the whole game.
We have seen it firsthand in the community. A handful of gold coins offered around 2,000 USD at a quick-cash shop turned out to be worth closer to 3,900 USD at a major bank the same week. Same coins, wrong first door.
Here is what actually works, what to avoid, and how to get real value for Mexican coins whether you are in the US or selling across the border.
First: is it bullion or is it collectible?
Everything depends on this one question, and most sellers get it wrong.
Bullion coins are valued mostly by their gold or silver content. These include the Centenario (a 50 pesos gold coin, 37.5 grams of pure gold, the classic Mexican gold piece), the Hidalgo gold coins, the Azteca, and the Onza Libertad (a one troy ounce silver bullion coin, .999 fine, still minted today). For these, price tracks the daily spot price of gold or silver. There is a hard floor: melt value.
Collectible coins carry a premium beyond metal. Sealed commemorative sets, older circulated pesos, mint errors, and low-mintage issues can be worth many times their metal weight. A silver 20 pesos Hidalgo 1995 in a sealed blister pack sells for well over 700 USD to a collector, but a bullion buyer will treat it as 27 grams of .925 silver and pay you around 40 USD. Same coin, seventeen times the difference, depending on who you sell to.
Sell bullion to bullion buyers. Sell collectibles to collectors. Mixing the two is where people lose the most money.
What bullion buyers and banks pay
For investment-grade pieces (Centenario, Azteca, Hidalgo gold, Onza Libertad), the fairest reference is a major bank or an established precious-metals dealer.
In Mexico, Banamex is the historic number-one buyer and an official Banxico distributor. Large branches in Mexico City, Monterrey, and Guadalajara buy these coins at spot price minus 3 to 5 percent, the tightest spread in the market. You will need ID, and for larger transactions (over the local anti-money-laundering threshold) you must show proof of origin. That rule is not optional.
Banorte and HSBC also buy, at spot minus 4 to 6 percent. Santander depends on the branch. BBVA buys only from private-banking clients, not the general public. Banco Azteca buys but at spot minus 5 to 8 percent, so you almost always net less there.
| Buyer | Typical spread vs spot | Open to public? |
|---|---|---|
| Banamex | minus 3 to 5% | Yes, large branches |
| Banorte | minus 4 to 6% | Yes |
| HSBC | minus 4 to 6% | Yes |
| Banco Azteca | minus 5 to 8% | Yes |
| BBVA | private-banking clients only | No |
If you are in the US, the same logic applies: reputable bullion dealers and coin shops that quote a live spot-based buyback price are your reference. Call or email three of them with the exact coin, weight, and date, then compare. The difference between the best and worst quote on the same gold coin is often 100 to 250 USD, and it takes fifteen minutes to find out.
Banks and bullion dealers are the wrong door for anything collectible. They pay metal content only and ignore the numismatic premium entirely.
Coin dealers and numismatic shops
This is where you sell everything that is not pure gold or silver: older pesos, commemorative sets, error coins, and pieces that require real numismatic knowledge to price.
In Mexico City, three names come up repeatedly in collector groups and Google reviews:
Casa de Moneda de México (the official mint, Legaria branch). They handle historic and modern pieces, pay close to real value with tight spreads, and are the most trustworthy option. They are also the most bureaucratic: paperwork, receipts, the full process. Worth it for an important piece.
Numismática Eclipse (several Mexico City locations). They buy and sell collector coins, buying at 4 to 6 percent below market and selling 6 to 8 percent above. You get a better price bringing assembled sets rather than loose coins.
Plata Mex and Monedas y Medallas de Palma (Centro Histórico). Similar structure, roughly 5 to 7 percent buy spread. Honest if you compare, but they know the market, so do not expect a bargain in your favor.
In the US, look for members of the American Numismatic Association or dealers who specialize in Latin American and world coins. Getting a US-based coin graded by NGC or PCGS before selling can raise the price substantially, because a certified grade removes the buyer's risk. Our dealer directory lists over 200 verified shops with reviews and notes on who pays best by coin type.
The collector forum: the channel almost nobody uses
For mid-value coins (roughly 50 to 1,500 USD), a collector forum pays better than any bank or dealer. The reason is simple: you reach the end buyer directly, with no middleman taking a cut. If your coin is worth 250 USD in the market, a shop pays you 200, a quick-cash buyer pays 150, but a collector who needs that exact coin to finish a series pays you the full 250 or a little more.
The catch: you have to know what you have. List "an old coin from my grandfather" with no photo of the edge and no condition grade, and buyers will lowball you every time. Describe it accurately, photograph it in natural light, and the right collector often appears within 24 hours.
To identify your coin and its real price range before selling, use the Pesoteca coin lookup, which gives you the market range and full technical data. Then post in the buy-and-sell forum with a clear photo and a price inside the catalog range. The unwritten rule: do not ask above the ceiling, do not sell below the floor.
Where NOT to sell
Pawn shops. They pay 30 to 50 percent of real value. Their business is lending against your coin, not buying it. Only worth it if you need same-day cash and do not care about losing half.
Unverified Facebook Marketplace. Honest collectors exist there, but so do scammers who pay with fake transfers and vanish. If you sell there, demand cash in person, in a public place, and never ship the coin first.
Jewelry stores that "buy gold and silver." They almost always pay metal content at daily price minus 15 to 20 percent, with no distinction between a historic Centenario and a plain bar. Same problem as banks for collectibles, but a worse spread.
Street cash buyers. They pay 7 to 9 percent below spot on gold and more than 30 percent below on collectibles, then flip the coin the next day at a 15 to 25 percent margin. Only justified if you need cash in hand and cannot wait for a bank's process.
The three-call rule
Before you sell any coin worth more than about 250 USD, do not let it go until you have quotes from:
- A major bank or reputable bullion dealer, if it is gold or pure silver.
- An established coin dealer, if it has any collectible component.
- A direct collector (forum or a serious collector group), if the coin has niche demand.
Three calls, one afternoon of work at most. The spread between the best and worst offer on the same coin usually runs 20 to 40 percent, far more than you earn in a normal day of work.
Have a specific coin and no idea who to call first? Come to the forum, describe what you have, and members will point you in the right direction for free. The community rule is to help the beginner, because everyone started there.
