Coin Metal Modification Authorization and Cost Savings Act of 2025

This bill lets the U.S. Mint change the metal mix of circulating coins to save taxpayer money. Any change must keep coins the same size and weight and let them work the same in most coin acceptors. Before changing anything, the Mint has to study the impact, get input from affected industries, and show that the change will cut costs and have as little negative impact as possible.

The Mint must give Congress at least 90 legislative days’ notice before making a change. Congress can stop a proposed change by passing a joint resolution of disapproval during that period. The bill also says how its budget effects are tracked under existing pay-as-you-go rules.

• Who is affected: U.S. Mint, businesses that use coin acceptors, and the public using coins.
• What changes: Allows coin metal changes to reduce costs, with required studies and industry input; coins must remain the same size and weight and work in most coin acceptors; Congress gets advance notice and can block changes.
• When: The Mint must notify Congress at least 90 legislative days before any change takes effect.
