The event is being hosted online by RR Auction’s Remarkable Rarities, with the bidding having opened on September 4th, 2024. Both of the Jobs-signed items are from the very early years of Apple.

The first is a handwritten company check, dated July 16th, 1976, and signed by Jobs. It was written to Elmar Electronics, for the amount of $10.52.

Check signed by Steve Jobs, written to a local electronics supplier.

A different Apple Computer check, also signed by Jobs, was made out to Radio Shack for $4.01 on July 23rd of that same year sold at auction in late 2023 for $46,063. RR Auctions estimates the new check will fetch at least $25,000, though as of September 14 at 10 AM ET, it currently stands at $12,650 after 14 bids.

The other item in the new auction is a cassette tape, also signed by Jobs, which served as an early way to store and retrieve data with the Apple II computer. This is first known example of a cassette tape with Jobs’ signature.

Presently, the autographed cassette has a top bid of $2,383 after eight bids. The auction house expects it fetch at least $10,000.

While primitive by today’s standards, the cassette interface system — designed by Steve Wozniak — was a big advance in early Apple computing. It was four times faster at storing or retrieving data than competing systems at the time, at a lower cost.

The auction will close to bidding on September 28th.
