Mexican Banknotes: Denominations and Key Details
Mexican banknotes (billetes) are issued in denominations of 20, 50, 100, 200, 500, and 1,000 pesos. Each note follows a standardized size and security feature set, with color-coded palettes and portraits of prominent historical figures. The 20-peso note typically features José María Morelos y Pavón; the 50-peso note honors Benito Juárez; the 100-peso note depicts Miguel Hidalgo y Costilla; the 200-peso note highlights Ignacio Zaragoza; the 500-peso note showcases Juan Aldama; and the 1,000-peso note presents Francisco I. Madero. Notes are polymer or cotton-based, depending on series, and integrate watermarks, security threads, and microprinting to deter counterfeiting.

Mexican Coins: Denominations, Designs, and Usage
Coins (monedas) are issued in denominations of 10, 20, 50 centavos, and 1, 2, 5, 10, and 20 pesos. The smaller centavo coins (10, 20, 50) are typically aluminum, while 1-peso coins are stainless steel with a brass ring and bronze center. Higher-value coins, including the 5, 10, and 20 pesos, are bi-metallic or nickel-clad steel with edge lettering and milled details. Designs highlight national symbols, historical figures, and landmarks. Mint marks, year of minting, and the legend “Estados Unidos Mexicanos” appear on most coins, and weight and diameter vary by denomination for easy identification.

Where and How Mexican Currency Is Used
Cash remains widely accepted across Mexico, especially in markets, street vendors, small shops, and taxis. Cards and contactless payments are increasingly common in cities and tourist areas, but smaller establishments may only accept cash. When paying in cash, examine notes for authenticity using light check for watermarks and security threads. Small coins are commonly used for public transportation, tolls, and low-cost purchases, while larger notes suit hotels, restaurants, and bigger retailers. Vendors may not always have change for high-denomination notes, so it is helpful to carry smaller bills when possible.
Exchange, Fees, and Practical Tips for Handling MXN
For the most favorable rates, use ATMs (cajeros automáticos) affiliated with major banks and withdraw in MXN rather than accepting dynamic currency conversion. Inform your bank of travel plans to avoid fraud alerts, and verify fees with your card issuer for international withdrawals. Compare exchange rates at banks and authorized exchange houses (casa de cambio), and avoid unofficial desks at airports or tourist hotspots. When counting change, verify coin denominations and be aware that “morlacos” or foreign coins are not legal tender and must be rejected. Carry a small amount of cash for places that do not accept cards, and keep digital or backup copies of important documents in a secure cloud service.
Historical Context and Series Updates
The Mexican peso (MXN) has been the official currency since the 19th century, with periodic redesigns to incorporate security features and new portrait series. Recent banknote series emphasize historical figures and cultural symbols, while coins have been updated with consistent sizing and modern metallics. Despite updates, lower-value legacy notes may still circulate for a time; vendors may be unfamiliar with older series, so verify authenticity through multiple security features. Older coin designs typically remain accepted at face value while supply phases out, though exact details can vary by bank and branch. Staying aware of series changes helps prevent confusion at point-of-sale and ensures smoother transactions.
