Ask a historian, a coin collector, and a traveller the same question, and you may get three different kinds of answer, yet all three point to the same word. If you search for the name of mexican money, the answer is the peso, the currency of Mexico since the country’s early years as an independent nation. What makes that simple answer interesting is the long road behind it: the peso did not appear from nowhere. It grew out of Spanish colonial coinage, survived independence, civil war, revolution, inflation, and a major redenomination, and it still carries traces of that history in its name, its subdivisions, and its designs. This article tells the story behind the name of mexican money in order, and then explains the coins and banknotes that Mexicans use today.
Unlike a traveller’s spending guide, this history of the name of mexican money is organised as history first and denominations second. It begins with the meaning of the word peso itself, follows the currency through the colonial period and the nineteenth century, explains the twentieth-century changes that shaped the modern peso, and finishes with a clear account of today’s coins and banknotes, their security features, and their place in Mexican culture. Readers who want the name of mexican money only need the first paragraph. Readers who want to understand why the peso looks and works the way it does will find the full story below.
Name of Mexican Money: Where the Word Peso Comes From
The name of mexican money comes from the Spanish word peso, which originally meant weight. In the colonial world, silver coins were valued by their weight and purity, and a piece of eight, the famous Spanish dollar, was known in Spanish as a peso. The word therefore carried a practical meaning before it became the formal name of a national currency: a peso was a reliable weight of silver that traders across the Spanish empire, and far beyond it, accepted without much argument. That trust is part of why the peso became one of the world’s most widely circulated coins in the seventeenth and eighteenth centuries, reaching Asia and the Americas through trade routes that carried Mexican silver to distant ports.
When Mexico became independent in the early nineteenth century, the new nation kept the peso name rather than inventing a wholly new currency label. Continuity mattered: merchants, miners, and ordinary people already trusted the peso, and a familiar name helped the young republic’s money gain acceptance. The early Mexican peso continued to be based on silver, and its coins carried national symbols that replaced the Spanish crown with emblems of the new republic. From the start, therefore, the name of mexican money was both an economic tool and a statement of identity, linking everyday transactions to the country’s break with colonial rule.
Colonial Silver and the Piece of Eight
To understand the name of mexican money, it helps to picture colonial Mexico as one of the great silver producers of the early modern world. Mines in places such as Zacatecas and Guanajuato produced vast quantities of silver, which was struck into coins at the mint in Mexico City, one of the oldest and most important mints in the Americas. The standard large silver coin, the piece of eight, was divided into eight reales, and it circulated so widely that it became a kind of world currency long before modern global money existed. Traders in China, India, and Europe accepted it, and its design and weight influenced later currencies, including the early United States dollar.
The colonial system behind the name of mexican money was not tidy by modern standards. Coins were struck by hand and later by machine, weights varied slightly, and clipped or worn coins circulated alongside fresh ones. Yet the system worked because silver itself had value everywhere, and because the Mexico City mint’s output was enormous. For ordinary people, the important units were the real for small purchases and the peso for larger ones, and that pairing of a large unit with a smaller subdivision survives in the modern relationship between the peso and the centavo. The colonial peso therefore left two legacies: a name rooted in weight, and a habit of thinking in a main unit divided into a hundred smaller parts, which the decimal reforms of the nineteenth century would later formalise.
Independence and the Nineteenth-Century Peso
After independence, the history of the name of mexican money followed the turbulence of its politics. The new republic issued its own coins, but civil wars, foreign interventions, and changing governments meant that different authorities sometimes issued different money, and confidence in paper notes was fragile. Silver coins remained the backbone of the system, because people trusted metal they could weigh and test far more than printed promises. During the middle of the nineteenth century, Mexico moved towards a decimal system, dividing the peso into 100 centavos, which simplified arithmetic and aligned the currency with the decimal reforms taking place in several other countries.
The later nineteenth century brought attempts at greater stability for the currency behind the name of mexican money, including the gold standard era, when major currencies were tied to gold. Mexico’s experience with that system was mixed, and the early twentieth century, with revolution and economic disruption, again strained the currency. Banknotes issued by different banks circulated alongside government money, and their value depended heavily on which authority stood behind them. Through all of this, the peso name endured, even as the coins and notes carrying it changed. That endurance is one reason the modern peso feels so rooted: it is not a recent invention but the latest chapter of a name that Mexicans have used for generations.
Why the peso survived so many crises
The currency behind the name of mexican money survived crises because people kept using it for wages, prices, and savings despite the turmoil around them. In Mexico, the peso survived because it was embedded in mining, farming, trade, and daily markets, and because each new government, whatever its politics, needed a working currency to pay soldiers, collect taxes, and buy supplies. Silver gave the early peso a physical anchor, and later reforms gave it institutional backing through a central bank. The name of mexican money became a habit as much as a policy, and habits in money are remarkably hard to break.
The Twentieth Century and the Nuevo Peso
The most important twentieth-century change for anyone handling the currency behind the name of mexican money came in the early 1990s, after a long period of high inflation had added many zeros to prices. In 1993, Mexico introduced the nuevo peso, or new peso, worth one thousand old pesos. Prices, wages, and bank balances were redenominated, so that a price that had read as thousands of old pesos became a far smaller number of new pesos. The word nuevo was dropped a few years later, and the currency reverted to being called simply the peso, but the redenomination explains why older Mexicans sometimes still talk about old and new pesos when recalling prices from before the change.
The redenomination was more than a cosmetic trimming of zeros. It was part of a broader effort to restore confidence, simplify accounting, and modernise the currency’s design and security. The central bank, the Bank of Mexico, took a central role in issuing banknotes and coins, setting monetary policy, and maintaining the currency’s stability. Modern Mexican banknotes and coins date largely from this period and from later redesigns, which is why today’s peso looks so different from the silver coins of the nineteenth century, even though it carries the same name. For collectors, the boundary between old and new pesos is a fascinating dividing line: coins and notes from before 1993 belong to a different price scale, even when their designs look familiar.
Name of Mexican Money: Coins in Circulation Today
Today’s coin system for the name of mexican money is practical, durable, and designed to be identified by touch as well as by sight. The main coins are the 1, 2, 5, and 10 peso pieces, supported by smaller centavo coins of 10, 20, and 50 centavos. The peso coins are bi-metallic, with a central disc set into an outer ring, a design that is both distinctive and difficult to copy cheaply. Each coin carries its value in numerals, the national coat of arms on one side, and a design linked to Mexican history or culture on the other. The 10 peso coin is the largest of the everyday coins, while the centavo coins are smaller and lighter, reflecting their smaller value.
Coin designs change over time through commemorative issues, which mark anniversaries, historical figures, or cultural themes. These special coins circulate alongside standard coins and are popular with collectors, but they spend at the same face value as any other coin of their denomination. A traveller or a new collector asking the name of mexican money does not need to learn every commemorative design: the numeral on the coin is the reliable guide to its value. The centavo is the subdivision that gives the system its precision, since one peso equals 100 centavos, and prices in shops are often written with two decimal places to show centavos, even when the smallest coins are rarely handed over in practice.
Name of Mexican Money: Banknotes in Circulation Today
Mexican banknotes, the notes behind the name of mexican money, are among the most colourful and information-rich in the world, and each denomination tells part of the country’s story. The notes in current use are the 20, 50, 100, 200, 500, and 1000 peso notes. Each denomination has its own colour, size, and pair of themes: one side typically honours a historical period or figure, while the other celebrates a natural landscape, an animal, or a cultural heritage site. The result is that a set of banknotes doubles as a pocket gallery of Mexican history and geography, from pre-Hispanic civilisations and independence heroes to deserts, forests, and coasts.
Modern notes also carry serious security features, including raised printing, watermarks, transparent windows on polymer notes, colour-changing elements, and micro-printing that is hard to reproduce. The 20 peso note, the smallest, is often printed on polymer for durability, since low-value notes change hands constantly. Higher notes use a mix of polymer and paper depending on the series. For everyday users of the currency behind the name of mexican money, the key skill is the same as for coins: read the large numeral first, then use colour and size as confirmation. The designs reward a closer look, but the numeral is what matters at a market stall or a ticket window. Those who enjoy the symbolism of Mexican national imagery may also like reading about what the colours of the Mexican flag mean, since the flag’s colours and emblem reappear across coins, notes, and public life.
Peso Denominations Explained
The table below sets out the modern system behind the name of mexican money in a single view, so that the relationship between coins, banknotes, and centavos is clear at a glance. It is the reference to keep beside the historical sections above: the names have deep roots, but the denominations listed here are the ones in daily use now.

The Peso in Culture and Collecting
Beyond economics, the peso, the answer to the name of mexican money, has a cultural life. Its coins and notes are souvenirs, teaching tools, and collectors’ items. Schoolchildren learn national history partly through the figures on banknotes, and visitors often keep a low-value note or coin as a memento long after the holiday ends. Collectors value older silver pesos, revolutionary-era notes, and commemorative coins, and they judge them by rarity, condition, and historical interest rather than face value alone. A worn silver peso from the nineteenth century may be worth far more to a collector than its face value suggests, while a crisp modern note is valuable mainly because it spends well.
For anyone planning to see the places pictured on the currency, or simply to travel in Mexico with a better sense of context, general trip planning material such as family travelling guides can help with the practical side of a journey, from transport to daily routines, while the currency itself remains the thread that connects markets, museums, and monuments. The peso’s story is, in miniature, Mexico’s story: silver wealth, independence, reform, crisis, and renewal, all carried in the pocket.
Frequently Asked Questions About the Peso
What is the name of mexican money in full?
The full name is the Mexican peso, shortened to peso in everyday speech, with the currency code MXN. The code distinguishes it from other currencies that also use the peso name.
What is a centavo?
A centavo is one hundredth of a peso, so 100 centavos make one peso. Centavo coins cover the smallest amounts, while peso coins and banknotes cover everything above them.
What was the nuevo peso?
The nuevo peso was the redenominated peso introduced in 1993, worth one thousand old pesos. The word nuevo was later dropped, and the currency is now called the peso again, but the change reset the price scale after years of inflation.
Why do Mexican banknotes look so colourful?
Each denomination uses its own colour and design themes drawn from Mexican history, culture, and nature. Colour helps users tell notes apart quickly, while the imagery turns everyday money into a showcase of national heritage.
Conclusion
The name of mexican money, the peso, is short, but its history is long. Born as a weight of silver, carried around the world by colonial trade, kept through independence and revolution, decimalised into pesos and centavos, and reborn as the nuevo peso in the 1990s, it has adapted to every era without losing its name. Today’s coins and banknotes, with their bi-metallic coins, colourful notes, and layered security features, are the latest form of that old idea: money that people recognise, trust, and use every day. To hold a peso is therefore to hold a small piece of Mexican history, and to understand its denominations is to understand how that history still shapes daily life.
