Elvis Presley’s luxury planes, the Lisa Marie and Hound Dog II, are up for sale in a sealed bid auction at Julien’s Auctions, reports USAtoday.com.

Presley, who would have turned 80 next week on Jan. 8, bought the Lisa Marie, a Convair 880 jet, from Delta Airlines in 1975, for $250,000. After refurbishing, it was valued at $600,000.

The jet, named after the late rock ‘n’ roll legend’s only child, included a penthouse bedroom with a custom queen-sized bed, and a bathroom with gold faucets and gold washbasin.

The Hound Dog II is a Lockheed JetStar that Elvis bought in 1975 while waiting for the Lisa Marie to complete its renovation.

In July 2014, Priscilla Presley famously asked fans of her late husband to “please calm down” after rumors of the planes’ departure from their Graceland home of more than 30 years swirled across the Internet.
