The silver rounds on this page are official mintages of the Mexican Mint. The onza was first produced in 1949 as a medallic issue featuring a coin press on the obverse and a balance scales on the reverse. Onzas of this design were produced in 1949 and again in 1978, 1979, and 1980. The libertad featuring the winged angel of victory has been produced since 1982. A completely new design was introduced in 1996. The reverse was redesigned in 2000 to feature a modern Mexican Eagle within a circle of obsolete versions.
