Elvis Presley's very first recording will be auctioned off at his sprawling estate, Graceland, on Jan. 8, in honor of what would have been the singer's 80th birthday.

The acetate disc, which is the only copy in existence, has 'My Happiness' on one side and 'That's Where Your Heartache Begins' on the other side. According to the New York Times, Presley paid $4 to record the two songs at the Memphis Recording Service, which was run by Sun Records, on July 18, 1953. Both songs were later included in future recordings, although this particular disc with the two songs has not been shared until now.

The purpose of the record is unclear. Some say it was a present for his mother; others suggest the singer wanted to hear how his voice sounded on a recording, or that he recorded the songs to get the attention of Sun Records. Presley began working with the label in 1954.

Official estimates for the value of the record have not been disclosed, but British magazine Record Collector suggests it is worth in excess of half a million dollars.

Other items that will be included in the auction are Presley's first driver's license, from 1952 (when he was 17 years old), a signed contract for an appearance on the 'Louisiana Hayride' radio show in 1955 and his first single for Sun, 'That's All Right.'

All items up for auction are from a private collection and not part of the Graceland estate. A catalog can be purchased for $20 here.
