What Is the Mexican 100 Peso Coin?

A simple guide to a coin with many stories

Is there a Mexican 100 peso coin? Yes—there are a few kinds. One is a big silver coin from 1977–1979. Another is a yellow coin from 1984–1992. Newer 100s were made mainly for collectors. You don’t see them much in change. :contentReference[oaicite:0]{index=0}

Quick answer

The “Mexican 100 peso coin” can mean three things:

  • 1977–1979 silver coin with José María Morelos.
  • 1984–1992 base-metal coin with Venustiano Carranza and “100” in Braille.
  • 2003–2007 collector coins that are two-metal and have a silver center.

All are real. They just come from different times and uses. :contentReference[oaicite:1]{index=1}

Meet the big silver coin (1977–1979)

  • Shows hero José María Morelos on one side; the eagle and snake coat of arms on the other.
  • Silver purity is .720; silver weight is about 0.643 troy oz; diameter about 39 mm.
  • Heavy, shiny, and popular with collectors. :contentReference[oaicite:2]{index=2}

Meet the yellow Carranza coin (1984–1992)

  • Shows Venustiano Carranza; the number “100” appears in Braille at the top.
  • Made of an aluminum-bronze mix; about 26.5 mm across and ~11.8 g.
  • These older 100s were demonetized on November 15, 1995, so they’re no longer valid to spend. (They’re still collectible.) :contentReference[oaicite:3]{index=3}

The modern collector 100s (2003–2007)

  • Two-metal design: a yellow ring with a silver (.925) center of about 1/2 oz.
  • Many show the coats of arms or culture of Mexico’s states.
  • Made mainly for collecting, so you hardly ever get one in change. :contentReference[oaicite:4]{index=4}

So…what is it worth?

  • Silver 1977–1979: value tracks the silver it contains (about 0.643 troy oz) plus any collector premium. :contentReference[oaicite:5]{index=5}
  • 1984–1992 base-metal: not spendable today; value comes from condition, dates, and collector interest. :contentReference[oaicite:6]{index=6}
  • 2003–2007 collector: often priced like collector pieces because of the silver center and themed designs. :contentReference[oaicite:7]{index=7}

How to tell which 100 you have (fast)

  • Big and silver? Likely 1977–1979 Morelos.
  • Yellow, mid-size, with Braille “100” on top? 1984–1992 Carranza.
  • Two colors with a bright silver center? 2003–2007 collector coin showing a state theme. :contentReference[oaicite:8]{index=8}

Tips for new collectors

  • Check the year and design first. That tells the story.
  • Weigh and measure if you can. Size and metal help you know value.
  • Keep coins dry and clean. Store in a soft holder to avoid scratches.

Bottom line

“The Mexican 100 peso coin” is not just one coin. It is a family of coins from different years and jobs—some for pockets, some for pride, and some for collectors. That’s what makes it fun to find and learn about. :contentReference[oaicite:9]{index=9}
