July 1, 1976: The Apple 1 goes on sale, becoming the first computer ever sold by the Apple Computer Company.

Arriving the same month Jimmy Carter was nominated for U.S. president, Family Feud debuted on TV, and the United States celebrated the 200th anniversary of its Declaration of Independence, the Apple 1 is only produced in small numbers, and sells for the unusual price of $666.66.

On June 24, 2013, an Apple I — the first ever computer built by Apple Computer, Inc. — was listed for auction by international auction house Christie’s.

Thought to be one of the first 25 units to be built by Steve Jobs and Steve Wozniak in the late 1970s, the unit featured no Apple logo, but rather a signature from Woz, who designed the machine. It sold for an impressive $390,000, ranking it among the most expensive computers ever sold.
