50 Dollars - Elizabeth II Pedro Menendez de Avila

Pedro Menéndez de Avilés founded St. Augustine, Florida in 1565 — the oldest continuously occupied European settlement in what is now the United States — after routing a French Huguenot colony at Fort Caroline with calculated brutality. His campaign was as much a religious purge as an act of conquest. Spain authorized the massacre of French survivors explicitly on grounds of heresy, not war.

Cook Islands issued heavily in the early 1990s through the World Mint and similar licensing arrangements, producing commemorative silver largely for the collector market rather than any domestic monetary purpose.
