Winning the Nobel Prize brings with it a diploma, cash award, and a 200 gram medal made of gold. Each medal is specially cast for the winner, emblazoned with his or her name.
When the Nazis invaded Copenhagen in 1940, physicist Niels Bohr was in possession of two Nobel Prize medals. But they were not his medals. The first belonged to Max von Laue, winner of the 1914 Prize for physics, the second to James Franck, the physics winner in 1925.
