Elton John Auctioning Off Rare Collection Of Items From Atlanta Home

Elton John is auctioning off some incredible finds from his gorgeous Atlanta home ... and bidders can get their hands on some of the Rocket Man's most recognizable memorabilia.

The auction, called "The Collection of Sir Elton John: Goodbye Peachtree Road" is going down next month at Christie's in New York -- with everything belonging to the singer coming from his condo in Georgia, which he bought back in 1992.

Folks can bid on a diamond necklace that says "The Bitch Is Back," which is expected to fetch up to $40,000 ... or a pair of performance-worn silver platform boots with his initials on it, which could snag $10k.

Elton's beautiful grand piano is also heading to the auction block, and is expected to go from $30-50k ... and we're guessing something like that comes with a lot of history.

Also up for auction are more pieces of his elegant wardrobe, photographs, a unique 18K gold watch, a Julian Schnabel portrait of Elon -- which could make up to $300k -- and other artwork.

Bids open next month, and the exhibit will be open to the public throughout February at Christie's NYC showroom ... so start saving now if you're a mega fan and want some of this stuff.
