Coin Metal Modification Authorization and Cost Savings Act of 2025

The Coin Metal Modification Authorization and Cost Savings Act of 2025 would authorize the Director of the United States Mint, with input from the Secretary, to change the metallic composition of circulating coins. The changes would be allowed if a Mint study shows they would reduce taxpayer costs, while ensuring the new coins are seamless (the same diameter and weight as current coins and usable in most coin-accepting machines that rely on electromagnetic signatures) and cause minimal adverse effects on the public and stakeholders. Before making a modification, the Director must notify Congress at least 90 legislative days in advance with justification, cost-saving rationale, and assurances about seamlessness and public impact. Congress can disapprove the modification via a joint resolution within that 90-day window, after which the Director could begin the change. The bill also directs that budgetary effects be evaluated under PAYGO rules. In short, this bill creates a formal process for altering coin metals to save money, while requiring study, stakeholder input, technical compatibility, congressional oversight, and adherence to existing budget rules.
