The Nobel Prize medal of celebrated American geneticist James Watson sold for $4.75 million in justminutes at auction on Thursday in New York.

The sale, the first of a Nobel Prize by a living laureate, was considerably more than the $2.5-$3.5 million estimate, the auction houseChristie's said.

Watson was awarded the prize in 1962 for discovering the double-helix structure of DNA nine years earlier -- one of the 20th century's mostimportant scientific findings.

But the 86-year-old's reputation took a major hit after he questioned the intelligence of black people -- comments for which he subsequentlyapologized -- and he has been shunned ever since by some in the scientific community.

Made of 23-karat gold, the medal features the profile of Swedish chemist and inventor Alfred Nobel.

Christie's also sold Watson's handwritten notes for his speech during the Nobel banquet on December 10, 1962. Valued at $300,000-$400,000,the fives pages went under the hammer for $365,000.

Watson had also participated in the Nobel conference. A corrected, 46-page manuscript valued at $200,000-$300,000 sold for $245,000.

The author of numerous scientific volumes, Watson intends to donate a portion of the proceeds to the University of Chicago, where he studied,Clare College at the University of Cambridge, where he worked, and Cold Spring Harbor Laboratory, where he served as president for many years
