How crucial is it that we have a Hip-Hop wing at the Smithsonian Museum of American History? Pretty crucial, according to 50-Cent, Kanye West and Missy Elliot.

They, along with some others, are auctioning off some of their jewelry to benefit the National Museum of American History’s drive to establish a permanent hip-hop exhibit.

The auction is on March 5th in New York City, so start saving.
