The Richardson family is auctioning off the rocker’s former resting place in order to raise money to fund a musical tribute show honoring the Big Bopper, according to the Beaumont Enterprise.

Following a 2007 exhumation and autopsy of the singer’s body, Richardson was reburied in a new casket at a new site, and the old casket was put on display at the Texas Musician’s Museum.

The museum will receive a portion of the proceeds from the sale of the casket, which director Tom Kreason called a “priceless” artifact that represents the historic day, Feb. 3, 1959, when rock ’n’ roll lost three stars in a plane crash – Richardson, Buddy Holly and Ritchie Valens.

“We gave it a name,” Kreason told the Enterprise. “We called it ‘the day the music died’ and there’s no title bestowed on any other tragic days since. No one knew, then, what was being created. This [casket] is very symbolic of how we lost three incredible artists, but it’s also a statement about what we’ve lost with many other artists too.”
