The 2012 Star-Spangled Banner Commemorative Coin Program was a commemorative coin series issued by the United States Mint in honor of the bicentennial of the writing of the Star-Spangled Banner, which is the national anthem of the United States. The program consisted of three coins: a $5 gold coin, a silver dollar, and a clad half-dollar. The designs of the coins featured various elements related to the Star-Spangled Banner, such as the flag, the words of the anthem, and the Battle of Baltimore. The coins were available for purchase from the United States Mint from March 5, 2012, through December 17, 2012. A portion of the proceeds from the sale of the coins went to support the Maryland War of 1812 Bicentennial Commission and the Star-Spangled Banner Flag House in Baltimore, Maryland. The Star-Spangled Banner Commemorative Coin Program was authorized by the United States Congress through the Star-Spangled Banner Commemorative Coin Act, which was signed into law by President Barack Obama on May 26, 2010.
