100 Pesos 1984 (Carranza): What It's Worth Today

If you inherited a Mexican 100 pesos coin dated 1984 with a bearded man on it, here is the honest answer: in circulated condition it is worth close to face value, usually under 2 or 3 dollars. It is not silver, it is not rare, and it is not a fortune. But a pristine, uncirculated example can bring more, and that is the part most people miss.

What this coin actually is

The 1984 100 pesos is an aluminum-bronze circulation coin, not a precious metal piece. The bearded portrait is Venustiano Carranza, a leader of the Mexican Revolution. It was struck at the Casa de Moneda de México (the Mexican Mint), which has produced the country's coinage for centuries.

Here are the exact specifications, useful if you want to confirm what you have:

Feature	Detail
Denomination	100 pesos
Year	1984 (struck multiple years)
Composition	Aluminum-bronze
Weight	11.71 grams
Diameter	26 mm
Edge	Discontinuous reeded
Portrait	Venustiano Carranza (reverse)

This coin belongs to the last stretch of the "old peso" before the Nuevo Peso arrived in 1993. Those were years of heavy inflation, which is why a high denomination like 100 pesos ended up as everyday pocket change. It was minted across several years and produced in large numbers, so tens of millions passed through Mexican hands.

Is it worth money?

For most people reading this: no, not in any life-changing way. This is one of the most common Mexican coins from the 1980s. A worn example that spent years in circulation is worth roughly its metal and collector floor, meaning a couple of dollars at best. Do not expect a dealer to pay more than that for a scratched, dull coin.

What changes the math is grade. Because almost everyone spent theirs, high-grade survivors are less common than the mintage suggests. An uncirculated coin with full original luster and sharp detail in Carranza's beard is the one collectors actually want, and it can sell for several times the value of a worn piece. Even then we are talking about tens of dollars in top condition, not hundreds. Be realistic: this is an entry-level collector coin, priced for people just starting a Mexican series.

Where the real value sits

Three things decide what your 1984 100 pesos is worth:

• Grade. Circulated equals a few dollars. Uncirculated with full luster is where the premium lives.
• Genuine mint errors. Off-center strikes, die rotation, and double strikes, if verified as real, can multiply the value. Most "errors" people post online are post-mint damage (dings, corrosion), not factory errors.
• Completing a set. It has natural demand as part of a Mexican Revolution figures collection or a full 1980s circulation set.

How to tell if yours is genuine

Counterfeits of a low-value coin like this are uncommon, but if you want to be sure, measure it. Weigh it on a jewelry scale (it should be 11.71 grams) and check the diameter with calipers (26 mm). Fakes usually miss on weight or diameter, or show flat, mushy relief and uneven coloring. The edge should be a discontinuous reeded pattern you can feel with your fingertip.

Where to sell it

If you decide to sell, photograph both sides and the edge, and know your grade before you talk to anyone. Your options:

• A verified coin shop from the Pesoteca dealer directory, which can appraise it on the spot.
• The Pesoteca buy-and-sell forum, where collectors trade directly.

Do not dump it to the first bidder on social media, and check the value range on this page first so you know what a fair offer looks like. If you have a full run of 1980s coins, selling the set together often beats selling one coin at a time.
