A gold medal is a medal awarded for highest achievement in a non-military field. Its name derives from the use of at least a fraction of gold in form of plating or alloying in its manufacture.
Since the eighteenth century, gold medals have been awarded in the arts, for example, by the Royal Danish Academy, usually as a symbol of an award to give an outstanding student some financial freedom. Others offer only the prestige of the award. Many organizations now award gold medals either annually or extraordinarily, including UNESCO and various academic societies.
While some gold medals are solid gold, others are gold-plated or silver-gilt, like those of the Olympic Games, the Lorentz Medal, the United States Congressional Gold Medal and the Nobel Prize medal. Nobel Prize medals consist of 18 karat green gold plated with 24 karat gold. Before 1980 they were struck in 23 karat gold.
Before the establishment of standard military awards, e.g., the Medal of Honor, it was common practice to have a medal specially created to provide national recognition for a significant military or naval victory or accomplishment. In the United States, Congress would enact a resolution asking the President to reward those responsible. The commanding officer would receive a gold medal and his officers silver medals. Other countries similarly honored their military and naval victors in a similar fashion.
Medals have historically been given as prizes in various types of competitive activities, especially athletics.
Traditionally, medals are made of the following metals:
Occasionally, Platinum medals can be awarded.
These metals designate the first three Ages of Man in Greek mythology: the Golden Age, when men lived among the gods, the Silver Age, where youth lasted a hundred years, and the Bronze Age, the era of heroes.
