Profile of Sacagawea with her infant son, Jean Baptiste Charbonneau being carried on her back.

Sacagawea (1788-1812) was a Lemhi Shoshone woman who helped the Lewis and Clark Expedition achieve each of its chartered mission objectives exploring the Louisiana Purchase. With the expedition, between 1804 and 1806, she traveled thousands of miles from North Dakota to the Pacific Ocean, established cultural contacts with Native American populations, and researched natural history.

The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the first American expedition to cross what is now the western portion of the United States, departing in May 1804, from near St. Louis making their way westward through the continental divide to the Pacific coast.

The design features a profiled likeness of Sequoyah writing “Sequoyah from Cherokee Nation” in syllabary along the border of the design. Inscriptions are “UNITED STATES of AMERICA” “$1,” and “Sequoyah” written in English in the field of the design.

Sequoyah (ᏍᏏᏉᏯ Ssiquoya, as he signed his name, or ᏎᏉᏯ Se-quo-ya, as his name is often spelled today in Cherokee) (c.1770—1843), named in English George Gist or George Guess, was a Cherokee silversmith. In 1821 he completed his independent creation of a Cherokee syllabary, making reading and writing in Cherokee possible. This was one of the very few times in recorded history that a member of a pre-literate people created an original, effective writing system. After seeing its worth, the people of the Cherokee Nation rapidly began to use his syllabary and officially adopted it in 1825. Their literacy rate quickly surpassed that of surrounding European-American settlers.

In the Cherokee syllabary system each symbol represents a syllable rather than a single phoneme; the 85 (originally 86) characters provide a suitable method to write Cherokee. Although some symbols resemble Latin, Greek and Cyrillic letters, the relationship between symbols and sounds is different.
