Once again, a rare Apple I will be up on the auction block. According to a report from the AP, a 1976 Apple I will be up for grabs at Christie's auction house where the bidding will begin at US$300,000. It's estimated that the iconic computer may end up going for $500,000 by the time bidding closes.

"This is a piece of history that made a difference in the world, it's where the computer revolution started," said Ted Perry, a retired school psychologist who owns the old Apple and has kept it stashed away in a cardboard box at his home outside Sacramento, Calif.

It's estimated that only 200 or so Apple I units were ever produced, with the number of units still in existence believed to be in the 30-50 range.

Recently, Apple I machines have been fetching exorbitant amounts at auctions worldwide. This past May, for example, a working Apple 1 sold for $671,400 at a German auction house. Before that, an Apple I yielded $640,000 at a Sotheby's auction.

The Christie's auction, which will be held online, will begin on Monday, June 24 and will run through July 9.
