Mexican Gold Peso Values

Mexico produced more denominations of gold coins than almost any other country. From the tiny 2 Peso to the massive 50 Peso Centenario, each one contains a specific amount of gold that determines its minimum value. This guide covers every denomination across both production eras so you can figure out exactly what your Mexican gold coin is worth.

The 2 Peso is the smallest Mexican gold coin you'll commonly encounter. It's about the size of a shirt button and weighs just 1.67 grams. People often mistake them for tokens, jewelry components, or costume pieces. If yours shows the Mexican eagle on one side and "Dos Pesos" on the other, it's genuine gold.

At 0.0482 troy ounces of gold, the 2 Peso is worth roughly $242 at current prices. These were produced from 1919 through 1947, with many restrikes dated 1945. The 1919–1920 originals are scarcer than the 1945 restrikes.

The 5 Peso holds 0.1206 troy ounces of gold, worth approximately $606. The later series (1905–1955) features Miguel Hidalgo on the obverse. The earlier series (1870–1905) has a different design with the balance scale of justice and contains 0.2380 oz of gold at the older 87.5% standard, nearly double the gold of the later version.

The 5 Peso is a popular fractional gold coin because it offers meaningful gold content without a large price tag.

The 20 Peso is a large, impressive coin featuring the Aztec sunstone calendar on the reverse. The later series (1917–1959) contains 0.4822 troy ounces of gold, worth approximately $2,423. That's nearly half an ounce.

The earlier 20 Peso (1870–1905) contains 0.9519 oz, almost a full troy ounce, valued at roughly $4,783. That makes the 19th-century 20 Peso one of the most valuable Mexican coins by gold content, second only to the 50 Peso.

The Aztec calendar design makes the 20 Peso one of the most visually striking gold coins from any country. Collector demand for nice examples adds a premium above melt for coins in better condition.

The Gold Onza (1981 to present) is Mexico's modern one-ounce bullion coin, containing 0.9999 troy ounces of pure gold worth approximately $5,025. It features the Winged Victory on the obverse, similar to the Centenario but in a modern design.

People sometimes confuse the Gold Onza with the Silver Libertad, which shares a similar design. The gold version is smaller and heavier. If a magnet does not stick to it and it has noticeable weight for its size, it's likely gold.

Geography plays a role. Texas shares a 1,254-mile border with Mexico, and Mexican gold coins have crossed that border for generations. Families in Dallas, Austin, Houston, San Antonio, and El Paso regularly find Mexican gold pesos in inherited collections, safe deposit boxes, and estate sales.
