There's more than one way to get your hands on a Nobel gold medal.

The 1935 Nobel Prize in Physics awarded to English physicist James Chadwick for his discovery of the neutron will be offered this morning (June 3).

Sotheby's, which is handling the sale in New York, has estimated that the Nobel medal and its accompanying diploma will sell for $200,000-$400,000. (The 9 Biggest Unsolved Mysteries in Physics)

Selby Kiffer, Sotheby's international senior books specialist, sees the medal as a tangible piece of memorabilia for the discovery of something almost incomprehensibly small. (Neutrons are the uncharged particles found within the nucleus of an atom.)
