10 Dollars - Elizabeth II Theodore Roosevelt National Park

Theodore Roosevelt National Park in North Dakota — the only U.S. national park named for a living president at the time of its initial federal protection — was formally established in 1978, decades after Roosevelt's ranching years in the Badlands shaped his conservation philosophy more directly than any political office did. Cook Islands issued extensive commemorative silver programs throughout the 1990s under licensing arrangements that produced dozens of foreign-currency pieces honoring American subjects, a common revenue practice for small Pacific island nations with limited domestic coin demand.
