What Is the Mexican 1000 Peso Coin?

A tiny coin with a big number—and a cool history.

Quick! Is there a Mexican 1,000 peso coin? Yes—but it’s from the old money system. Mexico made a 1,000 peso coin from 1988 to 1992. It does not spend as cash today. Think of it like a time capsule you can hold.

What the 1,000 peso coin is (in one line)

The Mexican 1,000 peso coin is an old-peso circulation coin, made of aluminum-bronze, minted in 1988–1992, with Sor Juana Inés de la Cruz on it, and it’s no longer used for purchases.

Why a “thousand” isn’t huge anymore

In 1993, Mexico chopped off three zeros from prices. So 1,000 old pesos became 1 new peso. That’s why the coin feels big by number but small by value today.

Quick facts you can trust

Years made: 1988, 1989, 1990, 1991, 1992.
Metal: aluminum-bronze (goldish color).
Size & weight: about 30.5 mm wide, ~15 g.
Front (obverse): Mexico’s coat of arms (eagle and snake).
Back (reverse): Sor Juana Inés de la Cruz (a famous writer and nun).
Mint mark: “Mo” for Mexico City.
No longer legal tender: it was removed years ago, so it’s a collector item now.

How to spot the coin fast

Look for a warm golden color, the big “1000” on the back, and Sor Juana’s portrait. The edge has tiny ridges. If it’s silver-colored or super tiny, it’s probably a different coin.

Can I spend it?

Nope. Stores won’t take it. It’s for collecting, gifting, or teaching about money changes.

What is it worth today?

Most are a few dollars, more if they look extra nice or are uncirculated. It’s not a get-rich coin, but it’s a fun, real piece of history.

Coin vs. bill: don’t mix them up

Mexico does have a 1,000 peso bill today. That’s paper money. The 1,000 peso coin is from the old system. Coin = history; bill = modern cash.

Kid-friendly learning idea

Use the coin to show place value. Ask: “If 1,000 old pesos became 1 new peso, what happened to prices?” Kids can cross out three zeros and see the math magic.
