The Libertad coins are silver and gold bullion coins originating from Mexico and minted by the La Casa de Moneda de México (Mexican Mint). The Mexican Mint was established in 1535 and is the oldest mint in the Americas. The modern coins contain 99.9% silver or gold (.999 fineness) and are available in various sizes. Both metal coins have undergone a design change. In 1989, 3,500 ​1⁄4 ounce Libertad platinum coins were produced. Libertads are devoid of face value, yet are still accepted as currency and guaranteed by Banco de México based on the market value of its gold or silver content.

In addition to the bullion version, a proof and reverse proof versions for both metals are manufactured specifically for collectors. Proof coins contain a frosted angel with a polished background. A reverse proof is the opposite and has a polished angel with a frosted background. An antique finish is available in silver and is also sought out by collectors. An antique finish gives coins an aged appearance without any loss of detail. The antiqued finish usually displays portions that look as if they have toned darker. Proof and antique finish coins are minted in relatively small quantities and are considered more beautiful and valuable than the standard bullion coin.
