$500,000 for the "most important document in Apple's history"

"Steve Jobs & the Computer Revolution: The Apple 50th Anniversary Auction" is the name of an auction organized by RR Auction, which is no stranger to auctioning collectible items from Apple's history. The star item of this sale is a $500 check considered by computer historians to be the "most important document in Apple's history," as it was signed by two of the company's co-founders—Steve Jobs and Steve Wozniak—and is dated March 16, 1976, two weeks before Apple was officially founded on April 1 of the same year. Jackpot for numbers 0 and 1! This is a temporary check, issued before the creation of a bank account, used to pay Howard Cantin, designer of the circuit board for the very first Apple 1 computer. The number "1" is handwritten on it (by either Jobs or Wozniak), making it the very first check issued by Apple. Perhaps not a "founding document," but important enough to be estimated at $500,000. Other items in this sale include the "number 0" prototype of the Apple 1 computer's printed circuit board, also estimated at $500,000.
