The purpose of this legislation is to allow changes to the materials used in the production of U.S. coins in order to save federal funds. It aims to provide the U.S. Mint with the authority to modify the composition of circulating coins based on studies that show such changes would be cost-effective and minimally disruptive. Key provisions of the law include the ability for the Director of the U.S. Mint, in consultation with the Secretary of the Treasury, to alter the metallic composition of coins.
