The 25th anniversary of Tupac Shakur’s murder fell on September 13 yet items from his personal vault and those close to him continue to be unearthed — with a hefty price tag attached.

The latest 2Pac artifact to go on sale at auction is a hard drive belonging to the late rapper’s old bodyguard and friend, Frank Alexander, who has also since passed away.

According to Gotta Have Rock and Roll, where the item is being auctioned, the 83GB hard drive contains a treasure trove of unreleased ‘Pac content including music, photos, videos and legal documents.

“Some of the highlights on the hard drive include a 35 second clip from a never released song — which is incredibly rare in Tupac’s recording history,” reads the lot description. “The photos and videos bring you right into Tupac’s life in the mid to late ’90s and are some of the most intimate media that exists of him.”

The song in question is a never-before-heard version of “Letz Get It On (Ready 2 Rumble),” which was played at the Mike Tyson vs. Bruce Seldon fight 2Pac attended before he was murdered. Some of the photos, meanwhile, show the All Eyez On Me legend hanging out with with the likes of Suge Knight and Mike Tyson.

TMZ obtained a snippet of the unreleased 2Pac song, which can be heard below.

Alexander’s hard drive went up for sale on Wednesday (December 1), with bids starting at $10,000. Gotta Have Rock and Roll expect the item will fetch anywhere between $600,000 and $1.2 million.

A 10 percent portion of the auction sale will be donated to the Tupac Amaru Shakur Foundation. Those interested can place a bid here.

Alexander’s hard drive would be far from the first piece of Tupac Shakur memorabilia to fetch a large sum at auction. Last year, a collection of 22 “sweet, poetic” love letters written by 2Pac when he was 16 sold for $75,600 at the London auction house Sotheby’s.

“I just want to be less sensitive and less of a pest,” a young ‘Pac wrote in one letter sent to his high school girlfriend at the time, Kathy Loy. “What I am feeling has to do with my insecurities, and I have to handle that on my own.”
