The 2005 $2 Westward Journey Nickel Series is a collection of five-cent coins that were released by the United States Mint to commemorate the bicentennial of the Lewis and Clark expedition. The series includes four different designs: “Ocean in View”: This design features a depiction of William Clark and his fellow explorers standing on the Pacific Coast, gazing out at the ocean. “American Bison”: This design features a bison, which was an important symbol of the American West and a key source of food for Lewis and Clark’s expedition. “Keelboat”: This design features a depiction of the keelboat that Lewis and Clark used to travel up the Missouri River. “Peace Medal”: This design features a reproduction of the peace medal that President Thomas Jefferson commissioned for Lewis and Clark to give as gifts to Native American tribes they encountered on their journey. The 2005 $2 Westward Journey Nickel Series was the first time in 66 years that the United States Mint had changed the design of the nickel. The series was well-received by coin collectors and the general public alike, and it continues to be a popular collection among numismatists.
