IIRC an MOH recipient can request an extra medal. For instance, have one to wear, and another to display in a shadowbox.
Ah, thank you!
“Medal of Honor recipients may apply in writing to the headquarters of the service branch of the medal awarded for a replacement or display Medal of Honor, ribbon, and appurtenance (Medal of Honor flag) without charge. Primary next of kin may also do the same and have any questions answered in regard to the Medal of Honor that was awarded.”
