The 1991 1oz Silver Libertad Bullion Coin is struck by Casa de Moneda de México as a bullion issue with 1oz of .999 fine metal content. It forms part of the Silver - Libertad range, a recognised bullion series collected by date, design and condition.
The obverse features Mexican national coat of arms with eagle and snake, while the reverse carries Winged Victory with the volcanoes Popocatépetl and Iztaccíhuatl. This pairing gives the 1991 issue its own place within the wider run and helps distinguish it from neighbouring dates.
Annual bullion issues like this are valued for their precious-metal content as well as their role in complete date runs. Condition, availability and demand for the wider series can all influence collector interest over time.
