Maker: Steve Wozniak for Apple
Original Price: $2,995*
Worth Today: $200,000*

Though the technology of the Apple I computer is far behind the MacBooks we have today, an Apple I can still net $175,000-$475,000 at auction, thanks to nostalgic collectors with money to spend. The ones that sell for the most come with the original instruction manuals and built-in keyboards.

The Apple I cost $666.66 when it was released (the equivalent of $2,995 in today’s money). The Apple I was hand-built and designed by Steve Wozniak, and Steve Jobs helped him sell it. The computer was released in April of 1976 and discontinued a year and a half later when the Apple II came out.
