5 Onzas 'Libertad'

The Libertad series, launched by Banco de México in 1982, was a direct response to the global investment coin market that had been dominated by the South African Krugerrand and the Canadian Maple Leaf. The 5 onzas denomination entered the series later, targeting institutional and large-scale bullion buyers rather than casual collectors. Mintages for individual years in this size have occasionally dropped into the hundreds — the 2012 proof issue, for instance, had a reported mintage of around 600 pieces — making date runs genuinely difficult to complete.

Unlike sovereign bullion programs from the U.S. or U.K., the Libertad carries no face value, which means its legal tender status is ambiguous under Mexican law.
