5 Dollars - Elizabeth II Colonel Roosevelt

Theodore Roosevelt's post-presidential African safari of 1909–1910, funded by the Smithsonian Institution, resulted in over 11,000 animal and plant specimens shipped back to Washington — a haul so vast it took years to catalog. The expedition made Roosevelt an international figure of a different kind than the Rough Rider mythology had produced, and the "Colonel" designation reflects his preferred title after leaving office, which he considered more honest than "Mr. President."

Cook Islands has issued Roosevelt-themed bullion under its collector program for several years, with KM# 1928 among the later additions to that run.
