The new coins first entered circulation on July 7, 1975, when the half dollar was released in conjunction with ceremonies in Minneapolis, Huntington's hometown. The quarter followed in September and the dollar in October, each also with ceremonies to mark the issuance. The pieces were struck in numbers exceeding those needed for circulation; a Mint spokesman stated, "The theory in striking them was to have enough available so as many Americans as possible would have an opportunity to have a coinage commemoration of the Bicentennial year. They're mementos."
