100 Pesos Zacatecas 2012 (Herencia Numismática II)

If you found a large bimetallic Mexican 100 Pesos coin dated 2012 with "Zacatecas" on it, here is the honest answer: it is a collector piece with a silver center, not a rare treasure worth thousands. Its value comes from two things, the silver in the middle and a modest collector premium, and it depends heavily on condition and whether you still have the original case.

This is the 100 Pesos coin from the Herencia Numismática de México series, which translates to "Numismatic Heritage of Mexico." It was issued by Banxico, Mexico's central bank, as part of the second run of that program. Each coin in the series honors a Mexican state; this one is dedicated to Zacatecas. These were made for collectors, not for spending, so they almost never turn up in change.

What you actually have

The coin is bimetallic, meaning it has two parts: a silver center and an outer ring of a different metal. That is important, because the silver is only in the middle, not the whole coin. Anyone quoting you a "silver value" for the entire piece is wrong.

Here are the verified specifications:

The 39 mm diameter is the large format Banxico uses for its big commemorative collector coins. The commemorative face carries the Zacatecas design with a matte-and-shine finish, where polished relief stands out against a textured background. The obverse carries the Escudo Nacional, the Mexican national coat of arms, the same emblem you see on every Mexican commemorative.

Is it rare?

We do not have the official mintage recorded in our database, so we are not going to invent a number or call it "scarce" without proof. What is verifiable: this was a silver collector issue, not a circulation coin. It was never meant to be spent, so you will not find it at a bank counter. That collector origin is what gives it a premium above metal value, but it does not automatically make it rare or valuable.

What it's worth

Value rests on two legs:

1. The silver in the center. We do not have the exact silver content of this piece recorded, so we will not hand you a melt figure we cannot back up. Check the fineness and grams of silver on the original certificate or leaflet that came with the coin before you calculate any metal value.
2. The collector premium. This depends on grade (condition) and whether you still have the original capsule and presentation box. A coin still sealed in its case, with paperwork, sells for meaningfully more than a loose, handled example.

Because the market moves and prices swing with silver, we do not publish one fixed dollar figure. The honest way to find out what yours is worth today is to gather several real offers. Check the Pesoteca shop directory and compare against recent sales before you agree to anything. The rest of the series helps you see where this coin fits and what related pieces bring.

How to tell if it's genuine

Counterfeits of collector coins exist, so run these checks:

• Edge. It should be discontinuous reeded. A smooth or fully reeded edge is a red flag.
• Weight and size. Confirm 33.96 g on a precision scale and 39 mm across. Fakes are usually off on one or both.
• Design detail. A genuine coin has the Escudo Nacional on the obverse and a crisp Zacatecas design with a well-defined matte-and-shine finish. Blurry or flat detail suggests a cast copy.

If anything looks off, get a second opinion from a dealer in the directory before you buy or sell.

Where to sell it

Sell to buyers who understand collector silver: numismatic shops and collectors, not a bank and not a general pawn shop. The goal is to avoid getting paid only the silver value when the coin carries a collector premium. Use the Pesoteca shop directory to line up several offers side by side.

Have a Zacatecas 100 Pesos with the box and papers still intact, or one you suspect might be a fake? Post clear photos of both faces and the edge in the Pesoteca forum and let the community weigh in before you commit to a sale.

100 pesos silver Herencia Numismatica de Mexico series II, 2012, a reproduction of the Zacatecas 8 reales Type LVO. A piece from the second installment of the Bank of Mexico's Herencia project dedicated to the 8 reales struck at the Zacatecas mint, the principal provincial mint of New Spain during the 19th century. The Type LVO variant corresponds to the issues with assayers L, V, and O who shared the Zacatecas workshop in different periods between 1810 and 1830, producing the three letters on the reverse as a technical signature. Zacatecas was central to the Mexican mining-monetary system because of its proximity to the most productive silver mines in the north. The official weight of the reproduction is close to 31.10 grams with .999 silver fineness. The matte-brilliant finish combines a satin field with mirror relief. Under the administration of the Bank of Mexico led by Agustin Carstens in his second year at the helm. The complete series II included six pieces in 2012 dedicated to colonial and republican numismatic milestones. Collectible pieces for reproducing a documented regional variant of the early republican 8 reales.
