Silver Libertads struck by Casa de Moneda de México in .999 fine silver, each one certified and listed with its grade and certification number. Sizes here cover the 1 oz onza, the 2 oz and the 5 oz — the larger formats being where the mintages fall away sharply and the graded populations get genuinely thin.

The design has stayed remarkably consistent: the Angel of Independence over the volcanoes Popocatépetl and Iztaccíhuatl, with the Mexican coat of arms and its surrounding historical arms on the obverse. Proof and reverse-proof strikes, flag labels, picture-frame holders and Ultra Breaks presentations are all identified in the listing titles.

Dates in this collection run from the 1980s first-decade issues through current-year releases. Each slab is unique — when a certification number sells, that coin is gone.
