Coin Metal Modification Authorization and Cost Savings Act of 2025

This bill authorizes the U.S. Mint to change the metal composition of circulating coins if a study demonstrates it reduces taxpayer costs while maintaining the same size, weight, and compatibility with existing coin-operated machines. The Mint must submit a 90-day notice to Congress detailing cost savings and technical compliance before implementation, allowing Congress to block the change via a disapproval resolution during that period. It directly affects the U.S. Mint’s operations and businesses using coin acceptors (e.g., vending machines), but does not mandate immediate changes. The bill establishes a procedural framework for potential future cost-saving adjustments to coin composition.
