Mexico is the world's leading silver producer, and its coinage reflects that heritage. While other North American nations abandoned silver in the mid-1960s, Mexico continued to strike circulating silver coins—albeit at lower purities—well into the 1970s.
From the iconic "Caballito" Peso to the high-purity Hidalgo 10 Pesos, Mexican silver is prized by stackers for its beautiful artwork and the unique "Ley" system, where the silver fineness is often stamped directly onto the coin's design.
