The United States semiquincentennial redesign program included six circulating coin denominations.
The Circulating Collectible Coin Redesign Act of 2020 authorized redesigns for six denominations in connection with the 250th anniversary of American independence. The program covered the circulating coins used in everyday American commerce, while also setting special requirements for the quarter-dollar series.
The six-denomination figure is separate from the five quarter designs authorized under the same program. One denomination could therefore have multiple designs, while the overall program still covered six types of coins. The law also required the designs to be symbolic of the semiquincentennial.
Coin designs were to be chosen by the Secretary of the Treasury after consultation with the Commission of Fine Arts and review by the Citizens Coinage Advisory Committee. This process distinguishes official U.S. Mint redesigns from privately produced tokens or medals marketed with America250 themes.
