One of the first Apple computers ever made is currently up for auction.

A rare "Celebration" Apple-1 computer, which may have been built by Steve Jobs himself, is already going for more than $500,000 in an online auction with a few days left of bidding.

"This is the most unique, and quite possibly the first, Apple-1 ever created," the auction's website says in its description. Though it's likely impossible to know for sure if it's the very first Apple-1, it looks to be one of the earliest models in existence.

Apple cofounder Steve Wozniak has even weighed in on the computer, saying it's one of only a handful of boards that were manually soldered together -- none of which were ever sold to the public (the original owner was likely an early employee of the company.) The board may have even been built by Jobs himself, according to an Apple expert interviewedby Recode who noted Jobs put together many of the early boards.

The winning bidder will get a set that includes the Apple-1 computer with one of the first printed circuit boards, a 4K Byte RAM Expansion Memory, a Cassette Interface Daughter Board, BASIC Program Cassette Tape and Star Trek and Blackjack Program Cassette Tape, along with a set of original manuals and other documents.

The machine is going for $510,000 at the time of this writing but with three days left, the bids could easily climb far higher. Previous Apple-1 computers up for auction have gone for more than $600,000 and there's a good chance this one will fetch more given its uniqueness. Ten percent of the proceeds from the auction will go to the Leukemia & Lymphoma Society of Arizona.
