Coins are currency pieces issued by governments for circulation, typically made of metal and featuring designs that reflect national symbols, leaders, or historical events. Medals, on the other hand, are often created for commemorative purposes, awarded for achievements, or used in awards ceremonies, and they may not have legal tender status. In the United States, the U.S. Mint produces both coins and medals, with a significant issuance in 1976 to commemorate the nation's bicentennial, featuring designs that celebrate American history and independence.
