A new commemorative coin was unveiled Monday to mark the 100th anniversary of the end of World War I and honor those Americans who served.

The silver dollar coin, authorized by Congress in 2014, features a service member holding a rifle to honor those who fought in the war from 1914 to 1918.

Acting Army Secretary Ryan McCarthy and Army Chief of Staff Gen. Mark Milley unveiled the design on the first day of the Association of the U.S. Army’s annual meeting in Washington, D.C.

“It’s an opportunity to remember 4.7 million men and women who served 100 years ago,” McCarthy said. “Those soldiers performed their difficult mission and left a legacy that touches us all every day.”

No war should be forgotten, he said, and neither should anyone’s military service.
