The name of currency in mexico is the Mexican peso. That is the short answer, and it is the answer most readers are looking for when they type the question. The name of currency in mexico is used for everyday prices, wages, bank accounts, and government payments across Mexico, and its standard currency code is MXN. This guide explains the name of currency in mexico in full: what the peso is, how it is divided, what its coins and banknotes look like in general terms, how the currency symbol works, and how to avoid common confusions with other currencies that also use the word peso or the dollar sign. No exchange rates are stated here as current fact, because rates change constantly, and any rate quoted in a general guide would be out of date almost immediately. For a current rate, check a reputable bank, central bank, or financial data source at the moment you need it.
The full name, the Mexican peso, tells you two things at once: the country and the currency unit. In Spanish, the currency is called the peso mexicano. The word peso itself comes from a historical term for weight, and it has been used for currencies in several Spanish-speaking countries, which is why the country name matters. Saying simply peso, without saying Mexican peso, can be ambiguous, because Argentina, Chile, Colombia, Cuba, the Dominican Republic, the Philippines, and Uruguay have also used currencies called peso at various times. When you write or speak precisely, always pair the word peso with Mexican, or use the code MXN, to remove that ambiguity.
The Mexican peso is divided into 100 smaller units called centavos. In the same way that a dollar is divided into 100 cents, a peso is divided into 100 centavos. Prices in Mexico are therefore often written with two decimal places, such as a price shown as a whole number of pesos plus centavos. In everyday speech, people may round prices, drop the centavos when talking casually, or refer to amounts in pesos alone. In formal documents, bank statements, and price labels, the centavo part is normally shown, because even small differences matter when amounts are added up.
Name of Currency in Mexico: A Brief History
The history of the name of currency in mexico goes back to the colonial period, when Spanish silver coins circulated widely in the Americas. The peso became one of the most widely used silver coins in world trade, and its influence can still be seen in the history of the dollar sign and in the names of later currencies. After Mexico became independent, the country continued to use the peso, with many changes in design, in the issuing authority, and in the value of the currency over nearly two centuries. Banknotes and coins have been redesigned repeatedly to reflect Mexican history, culture, and security needs.
One important change came in the early 1990s, when Mexico introduced the nuevo peso, meaning new peso, as part of a currency reform. Three zeros were dropped from prices, so that 1,000 old pesos became 1 nuevo peso. After a transition period, the word nuevo was dropped, and the currency returned to being called simply the peso, or the Mexican peso in international use. Older references to the nuevo peso therefore describe the same currency lineage, not a different modern currency. If you meet the term in an old book or article, it usually refers to that 1990s reform, not to a currency in use today under a separate name.
The central bank and the peso
The Mexican peso is issued under the authority of Mexico’s central bank, the Bank of Mexico, known in Spanish as Banco de Mexico. The central bank is responsible for issuing banknotes and coins, for monetary policy, and for maintaining the stability of the currency’s purchasing power. That institutional role is similar to the role central banks play in other countries, and it is one reason the peso is treated as a major currency in international markets. The central bank also publishes official information about banknote and coin designs, security features, and withdrawn series, which is the best source if you need to check whether a particular note or coin is still in circulation.
Name of Currency in Mexico: Coins and Banknotes
Mexican coins and banknotes cover a range of denominations, and the exact set in circulation changes over time as new designs are introduced and old ones are withdrawn. Coins commonly include small centavo denominations and peso coins for everyday use, while banknotes cover larger amounts for shopping, travel, and larger payments. Designs often feature figures and themes from Mexican history, science, culture, and natural heritage, and each series includes security features designed to make counterfeiting harder. Because denominations and designs change, this guide does not list a fixed set as permanent, and readers who need to identify a specific note or coin should check the central bank’s current series.
The currency symbol for the Mexican peso is the same dollar sign used for several other currencies, which is a frequent source of confusion. In Mexico, prices are commonly written with that sign followed by the amount, but the same sign is also used for the United States dollar and for other dollar currencies. Context normally makes the meaning clear inside Mexico, where the sign means pesos, but in international writing the code MXN or the label MX is often added to avoid confusion. If you see a price online with only a dollar sign and no country context, do not assume which currency it means. Look for the code, the country, or the seller’s location before converting or comparing amounts.

Name of Currency in Mexico: Common Confusions
The most common confusion is between the Mexican peso and the United States dollar, because both use a similar symbol and because the two economies are closely linked through trade, tourism, and remittances. A price quoted in Mexico in pesos is not the same amount as the same number in United States dollars, and the difference can be large. Always check the currency code or the country context, and never convert by guesswork. A second confusion is between the Mexican peso and other pesos, as noted above. Argentina, Chile, and Colombia each have their own peso, with their own codes and values, and none of them is interchangeable with the Mexican peso.
A third confusion concerns old and new pesos. Some readers find old Mexican banknotes in collections or in family papers and wonder whether they can still be spent. Very old series are often no longer legal tender, even if they have collector value. The central bank publishes information about which series are current and which have been withdrawn, and that is the reliable source for such questions. Do not rely on a general guide, including this one, to decide whether a particular old note is still spendable. Check the official series information, and if in doubt, ask a bank in Mexico.
