Despite there being very few still in existence today, another Apple-1 computer is set to hit the auction block soon. As noted by The Telegraph, German auctioneer Team Breker will soon make a functioning Apple-1 available, estimating the machine will go for around $320,000.

Team Breker calls this Apple-1 the “best-preserved example of an Apple-1 computer to appear on the market.” The auction includes the Apple-1 itself, original operation documents, circuit diagrams, and purported notes of telephone calls between Steve Jobs and Steve Wozniak in 1977.

The Apple-1 will go up for auction on May 20th in Cologne, Germany. Team Breker currently expects the machine to go for “more than £250,000,” which is around $320,000 USD. Based on previous sales, auctions, if someone got their hands on this machine for $320,000, it’d be an absolute steal.

While there are very few out in the wild, we see Apple-1 units go up for auction on a semi-regular basis, but every time it’s a pretty notable event due to their historical and monetary value.

Last year, a rare Apple-1 “Celebration” model fetched $815,000 in auction. In 2014, a working Apple-1 was auctioned for $365,000, while the year prior a model signed by Wozniak went for $671,000. Another units as auctioned in 2015 and was expected to sell for over half a million dollars.
