A Congressional Gold Medal is an award bestowed by the United States Congress and is, along with the Presidential Medal of Freedom, the highest civilian award in the United States. The decoration is awarded to an individual who performs an outstanding deed or act of service to the security, prosperity, and national interest of the United States. American citizenship is not a requirement.
The Gold Medal and the Presidential Medal of Freedom are generally considered to carry the same level of prestige (though significantly fewer Gold Medals have been awarded). The chief difference between the two is that the Freedom Medal is personally awarded by the President of the United States (executive branch), and Congressional Gold Medals are awarded by acts of the Congress (legislative branch).
Per committee rules, legislation bestowing a Congressional Gold Medal upon a recipient must be co-sponsored by two-thirds of the membership of both the House of Representatives and the Senate before their respective committees will consider it.
A Congressional Gold Medal is created by the United States Mint to specifically commemorate the person and achievement for which the medal is awarded. Each medal is therefore different in appearance, and there is no standard design for a Congressional Gold Medal. Congressional Gold Medals are also considered "non-portable", meaning that they are not meant to be worn on a uniform or other clothing, but rather displayed much like a trophy. Often, bronze versions of the medals are struck for sale.
A Congressional Gold Medal is a completely separate decoration from the Medal of Honor, which is a military award for extreme bravery in action. Another similarly named decoration is the Congressional Space Medal of Honor, presented by NASA for extraordinary accomplishment to the mission of United States space exploration.
