Clark is going to auction off years of memorabilia from "American Bandstand," "New Year's Rockin' Eve" and his other shows.
Among the items to be sold by Guernsey's is Clark's microphone that he used as host of "American Bandstand." Also up for sale is a bass guitar that Paul McCartney played when he was a Beatle.
The auction will be held December fifth and sixth at the Rose Theater at Jazz at Lincoln Center, in Manhattan's Time Warner Center.
There will be no reserve set for the items, so they will all be sold to the highest bidder.
