When Was The First Sacagawea Coin Issued?

By GovMint :

The first Sacagawea dollar coin was issued in 2000 as an effort to create a new, widely-used dollar coin for circulation. The Sacagawea Dollar honors the famous Shoshone woman who played a vital role in the Lewis and Clark expedition, guiding them through the American West. Sacagawea and her infant son, Jean Baptiste, appear on the obverse in a masterful design created by Glenna Goodacre, which beautifully captures Sacagawea's strength and historical significance.

The series was issued until 2008. In 2009, it became the Native American Dollar series, which is still issued today and still features the iconic Goodacre Sacagawea design.
