Based on the provided search results, Mexico has a history of producing silver coins, often categorized as vintage. The provided context confirms their existence and notes that identifying specific silver coins can be complex, to the point where specialized world coin catalogs are often recommended for a complete listing. The search results, however, do not contain a detailed list of which specific coins contain silver.
Drawing from general numismatic knowledge, Mexico has a rich history of minting silver coins for both circulation and bullion purposes. A well-known modern example is the Mexican Libertad series, which are bullion coins produced from 1982 to the present and contain .999 fine silver.
Historically, many circulating Mexican coins contained silver, particularly before the late 1970s. For example, the large 1 Peso coins from the "Cap and Rays" era, minted until 1945, were made of 72% silver (.720 fine). Various other denominations, such as the 5, 10, and 25 Pesos, also had silver content during different periods. The 1968 25 Pesos coin, commemorating the Olympic Games in Mexico City, is a popular example containing 72% silver.
Silver was gradually removed from circulating currency. The 1 Peso coin from 1957 to 1967 contained only 10% silver. By the late 1970s, silver was generally phased out of regular coinage, with exceptions being commemorative issues and the bullion Libertad series. To definitively identify a specific coin's silver content, it is best to check its date, denomination, and design against a numismatic guide.
