The 2004 One Dollar coin, issued by the United States Mint in Philadelphia, is part of a series designed to commemorate the Lewis and Clark Expedition's bicentennial. These coins feature specific designs that reflect their commemorative purpose and are often sought after by collectors for their historical value and limited mintage.
