United States Foreign Service Commemorative Coin Act

Authorizes the Secretary of the Treasury to mint three commemorative coins honoring U.S. diplomacy and the Foreign Service, with detailed metal/content specifications, mintage limits, and required inscriptions. The coins may be produced in uncirculated and proof qualities and may be issued only during 2029; sales include set surcharges that will be paid to the Association for Diplomatic Studies and Training after the Treasury first recovers all minting and issuance costs.
