Coin Metal Modification Authorization and Cost Savings Act of 2023

S 1228, the Coin Metal Modification Authorization and Cost Savings Act of 2023, allows the U.S. Mint Director to change the metal makeup of circulating coins if a study shows it will reduce taxpayer costs while keeping coins the same size, weight, and compatible with existing coin acceptors. It directly affects the U.S. Mint (which would implement changes) and coin manufacturers/stakeholders who might be impacted by composition shifts. Key provisions require the Mint to conduct a study with industry input, certify changes meet cost-saving and seamless criteria, and provide Congress 90 days' notice before implementation, during which Congress could block changes via disapproval resolution. The bill focuses on procedural cost savings for the federal government without altering coin functionality or public use.
