It is believed that there are only 20 copies of the 14 love song CD collection, called Spinning Man, that exists.
In the 16 years since he put together the album, Sheeran has grown into one of the best-selling musical artists in the world and has an estimated fortune of over £ 200million.
The West Yorkshire-born star has previously said he doesn’t want anyone to ‘make a copy’ and that he has the remaining 19 CDs in his possession.
However, one of the demos was discovered, having been left in a drawer for years.
Sheeran was staying with relatives and sleeping on their couch, while making money playing on the streets, when he gave a signed copy to a friend of the parents.
The man’s brother, Kevin, 48, who does not want to give his last name, is now selling the CD.
Kevin told the PA News Agency, “My brother put it in a drawer and forgot about it.
“Back then, Ed Sheeran was just this little red-haired busker and he didn’t think about it. He didn’t know he was going to be one of the biggest pop stars in the world. ”
In his illustrated autobiography Ed Sheeran: A Visual Journey, Sheeran says he wrote the songs – with titles like Addicted and Misery – after parting with his first love.
Sheeran writes, “In 2004 I made my very first album, Spinning Man, named after a photo my dad had.
“I burned the CDs myself and made the covers. There were 14 songs, and they were all rhyming songs.
“A lyric would say, ‘I’m a typical average teenager if you know what I mean.
“There are probably 20 copies of Spinning Man, and I have 19. I don’t want anyone else to take a copy. ”
The 29-year-old added, “Most of the songs were about a girl called Claire. She was my first love when I was 13.
“It was a very innocent love, and we never held hands, but it lasted quite a while. Then came my first devastating breakup.
“Looking back, it really wasn’t that bad, but at the time it was overwhelming. When she left me, I wrote a lot of songs in the back – my first love songs. ”

Kevin told PA he was impressed when he heard the CD, comparing him to one of the best electric guitarists of all time.
“The quality of the songs is really good and I was shocked at how good he was on the electric guitar. It sounds like Eric Clapton at times.
” I play the guitar. The fact that he played like that when he was 13, he must have been talented from the start. ”
He said that Sheeran’s early songs “express teenage love and loss, frustration and desire.”
He also stated that the copy had a distinct characteristic: “Most other CDs – or all other CDs, as far as I know – have a sticker on the disc that says ‘Ed Sheeran Spinning Man’.
“But this one was missing stickers, so he wrote his name on the record and handed it to my brother.” So, this may be the only signed copy.
The album features cover photographs of Sheeran’s artist father, John Sheeran, and is expected to gross £ 10,000.
Auctioneer Paul Fairweather described the CD as “an important artefact in contemporary music history and a milestone in the development of one of the world’s greatest pop stars.”
The auction is expected to attract the attention of fans around the world.
Meanwhile, Sheeran is reportedly expecting his first child with wife Cherry Seaborn later this summer.
They tied the knot in a secret ceremony in Suffolk last summer.
Omega Auctions will sell the CD in its Music Memorabilia auction on September 8, 2020.
