Johnny Cash fans will soon be able to own up to 650 pieces of rock and roll history.

Just over a year after his death, Sotheby's will auction off memorabilia from the Cash estate on September 14 and 15 in New York. While Sotheby's doesn't list details on its Web site, The Associated Press reports that the auction will include pieces from Cash's wardrobe, a 1950s-era notebook full of his handwritten lyrics to such songs as "Cry Cry Cry," more than 50 instruments owned and played by Cash and his wife, June Carter Cash, seven of Cash's Grammy Awards, as well as a number of the couple's personal items, including photographs and jewelry. One of the more expensive pieces is a guitar that Cash designed, which is estimated at $15,000.

Sotheby's estimates the collection to be valued at about $1.5 million.
