Mexican peso essentials

mexican peso

The Mexican peso is the official currency of Mexico and is the third most popular currency in the Americas, after the U.S. and Candian dollars. Its roots trace back to Spain and it was the first currency to introduce design measures to prevent counterfeiting. 

In addition, it has several local nicknames, including: lucas, lana, marimba, money, morlacos, papiros, and varos. The Mexican peso is minted by the national central bank, the Bank of Mexico.

  • Currency code: MXN
  • Abbreviation: $ or Mex$, ¢ for centavos
  • Coins: 5¢, 10¢, 20¢, 50¢. $1, $2, $5, $10, $20, $50, $100
  • Banknotes: $20, $50, $100, $200, $500, $1,000

The 1000 pesos banknote is not very common, but it does exist! If you do come into contact with one, know that most small stores will not accept it because they won’t be able to make change for it.

The newest notes are made of plastic composite, making them very difficult to replicate. Since counterfeit notes were quite common, often sold to tourists, measures were taken to prevent fraud.

A short history of the Mexican peso

Imported from Europe during colonization, the peso originated from an earlier currency, the Spanish dollar. The Spanish dollar was also known as a “piece of eight.” Eight pesos were equal to one real.

After Mexico gained its independence in 1821, the government continued to use the Spanish monetary system.

In the mid-1800s, the Spanish dollar fell out of use in Mexico. The first minting of the coin peso was in 1866, which was made up of 100 centavos. Nevertheless, reales continued to be issued until the end of the 1800s. 

Gradually, the gold and silver content of the coins was replaced with less expensive metals. In 1905, the gold content of the peso was reduced by nearly 50%. This was followed by a reduction in silver. From 1918 to 1977, the weight and fineness of all silver coins declined, until the last silver peso coins were issued in 1977.

Throughout most of the 20th century, the Mexican peso was one of the more stable currencies in Latin America. However, the late 20th century was difficult for the Mexico peso. The 1970s oil crisis had devastated the Mexican economy. Not only did the country default on its national debt, but wealth left the country and the peso suffered from inflation.

The government later stepped in to create the economic strategy known as the Stability and Economic Growth Pact. To combat further devaluation, they introduced the nuevo peso (new peso) in 1993. A single nuevo peso equaled $1,000 old pesos.

Once the old notes and coins were out of circulation in 1996, the currency dropped the term nuevo

The “new” peso dropped three zeros off the old peso to adjust following years of inflation. Since people have been traveling to Mexico for decades, it’s not uncommon to still have old pesos. Some don’t realize that their value is actually less than what appears on the bill because of the new peso. Old peso bills and coins are no longer accepted by the Mexican public. However, if you have old pesos, you can cash them in at the Bank of Mexico.

The Bank of Mexico is still altering the peso today. The most recent change was to the figures on the $200 note in September 2019, which now features José María Morelos y Pavón alongside Miguel Hidalgo. 

The currency exchange rate in Mexico explained

If you look at the historical exchange rate charts for the USD to MXN, you’ll see that since 2016, the exchange rate has hovered around $20 MXN per $1 USD. However, it was much lower in the past. 

The Mexican peso is one of the most stable currencies in the Americas. Nonetheless, Mexico is considered an emerging market and its economy has taken a beating over the past few years. Due to COVID’s impact, the currency dropped another five points in 2020.

In addition, the Mexican peso’s value is affected by falling crude oil prices and rising interest rates.

6 fascinating facts about the Mexican peso

mexico money

While you might think that currency is pretty straightforward or even boring, every coin or banknote has a story. This is especially true for a currency with as much history as Mexico’s. 

Here are a few of our favorite facts about Mexico’s money:

1. Think $ stands for USD? Think again

It’s easy to see the dollar sign ($) and think of the US dollar. But it was the Mexican peso that first used the $ symbol for their coins!

The $ sign originates from the abbreviation ‘ps’, which was used to denote Spanish pesos in the Americas.

The reason the peso uses the same symbol as the dollar is because they share a common history. During the colonization of the Americas, Spain had the largest supply of silver — which is why the original peso was made from silver. What’s incredible is that this silver fueled the Chinese economy for over two centuries. In fact, the peso in Asia became the base of both the Yuan and Yen. Then in 1972, the US dollar was created. Modeled after the peso because of its international reputation and stability, the peso was still legal tender in the United States until 1857. Meaning, the US dollar and peso were originally the same coin.

2. The first peso banknotes weren’t printed in Mexico.

While the Bank of Mexico prints the modern-day peso, that wasn’t always the case. In their first round, the Mexican peso was printed by the American Bank Note Company of New York (ABNC) from 1925-1934. 

However, just because they were printed in ABNC doesn’t mean the Mexican people didn’t have any input. The Bank of Mexico told ABNC what they wanted on each note and sent images from their archive when possible.

Today, this is who you’ll find on some peso banknotes:

  • The 1000 pesos bill features Miguel Hidalgo, the Mexican hero who initiated Mexico’s independence
  • The 500 peso bill pictures Benito Juárez, the former Mexican president who was the first Mexican president of indigenous origin
  • The 200 peso bill features both Miguel Hidalgo and José María Morelos y Pavón, leaders and revolutionaries who fought for Mexico’s independence
  • The 100 pesos bill showcases Nezahualcóyotl, a philosopher, architect, poet, ruler, and warrior
  • The 50 pesos bill pictures José María Morelos, Mexican Roman Catholic priest and revolutionary
  • The 20 pesos bill features former Mexican president Benito Juárez

3. Peso literally means “weight.”

Peso is Spanish for “weight.’ This can be linked back to the Latin pensum, “something weighed,” from the verb pendere, “to weigh.”

When you consider that the peso used to be made of precious metals like gold and silver, it makes sense that the coin would be valued by weight.

This is also why pesos were commonly referred to as peso oro (gold weights) or pesos plata (silver weights).

4. It’s really hard to make counterfeit pesos.

Peso banknotes are designed and printed to prevent counterfeiting. For example, every note has a hidden watermark, holographic threads, and contains micro-prints. 

Furthermore, except for the $20 and $50 peso notes, all notes are printed on special banknote paper. This has the same feel or texture as USD or CAD. 

Some locations accept both USD and MXN.

Still have some Mexican pesos left when you travel back to the U.S.? If you’re stopping by any towns on the border, you may be able to use your MXN. 

Conversely, you’re often able to use your USD in Mexican cities and big resort towns. 

Mexico’s peso was an early currency model.

The Mexican peso was not only issued before the American dollar, but it also inspired its design. Because of its anti-counterfeit design, in fact, the peso was extremely popular during the 19th century. 

It’s no surprise, then, that many global currencies took their design cues from the peso. These include the Hong Kong dollar, the Japanese yen, and the Chinese yuan.

Getting the best deal for Mexican pesos


So, how can you get the best exchange rate when converting to pesos?

For tourists, you have a lot of options. You can use airport kiosks, ATMs (cajeros automaticos), currency exchange offices, or just your credit card. You can also order MXN from your bank before you even leave home.

Out of these options, you’re likely to get the best fees from an ATM or credit card. However, you’ll need to let your card issuer know that you’ll be out of the country. Otherwise, your bank may think that you’re a victim of identity theft and block your card. 

And you’ll want at least some cash on you. Medium and smaller shops likely won’t accept a credit card. Don’t forget to break big bills whenever you can. Anything over $200 pesos is considered large, and many vendors won’t be willing or able to provide change for a note that big.
