250th Anniversary of the United States Marine Corps Commemorative Coin Act

This bill directs the U.S. Treasury to mint commemorative coins marking the Marine Corps' 250th anniversary in 2025. It authorizes three coin types: $5 gold coins (max 50,000), $1 silver coins (max 400,000), and half-dollar coins (max 750,000), with surcharges of $35, $10, and $5 respectively. The surcharge proceeds will fund the Marine Corps Heritage Center's educational programs, with no net cost to taxpayers as the Treasury must recover all minting costs through the surcharges. The coins can only be issued during 2025, and the Treasury must ensure all costs are covered before distributing funds to the Heritage Foundation.
