The 5 Peso Mexican Gold Coin is struck by the Mexican Mint (Casa de Moneda de México), founded in 1535; see our full selection of Mexican Mint coins.
The Mexican gold peso coins sold here are struck by the Casa de Moneda de México (the Mexican Mint, founded in 1535) in .900 fine gold, meaning 90% gold by weight (21.6 karat). Because the fineness is the same across these denominations, the practical difference between the 5 Peso, the 10 Peso and the 20 Peso comes down to actual gold weight (AGW), which is the number buyers compare first.
| Denomination | Actual Gold Weight (AGW) | Fineness |
|---|---|---|
| 5 Peso | 0.1205 troy oz | .900 fine |
| 10 Peso | 0.2411 troy oz | .900 fine |
| 20 Peso | 0.4823 troy oz | .900 fine |
Read side by side, the 10 Peso carries twice the gold of the 5 Peso and the 20 Peso carries four times as much. In metric terms that is about 3.75 grams of fine gold for the 5 Peso, 7.5 grams for the 10 Peso and 15 grams for the 20 Peso. One 20 Peso therefore holds roughly as much gold as four 5 Peso coins or two 10 Peso coins. Gross weights follow the same pattern, with the 10 Peso listed at 8.333 g and the 20 Peso at 16.666 g on their product pages.
The smaller weight is the main reason to choose the 5 Peso: it allows finer increments when building a position one piece at a time, while the larger coins consolidate more gold into fewer pieces. Melt value follows the fine gold content, not the gross weight, and any quote depends on the market at the time of inquiry.
Each denomination has its own page with individual specifications: see the 10 Peso Mexican gold coin and the 20 Peso Mexican gold coin for details. The largest of the family is the Mexican 50 Peso gold coin (Centenario) at 1.2057 troy oz of fine gold — see it for full specifications and history.
