A piece of a well-known story about Steve Jobs’ disdain for giving autographs goes on the auction block Thursday.

At the 2006 opening of an Apple Store in New York City, the Apple co-founder initially refused the request of a man in a wheelchair who had hoped Jobs would sign his copy of the premiere issue of Macworld magazine.

Jobs, according to witnesses, was joking when he said no. He eventually acquiesced and signed the magazine, “To Matt” followed by “steven jobs.” (He rarely used capital letters when signing his name.)

Apple co-founder Steve Jobs had little time or interest in signing autographs for fans.

But if you are in possession of the rare exception, you have a signature considered the most valuable, according to a guide that tracks the values of the most sought-after autographs.

As Apple collectibles go, a Steve Jobs autograph is almost as rare as the Apple 1. Both are pricey investments.

However, a TIME magazine cover featuring Jobs and the signature he loathed giving out is kind of a bargain at a penny shy of $20,000.

John Sculley may be best known to a generation of Apple fans as the CEO who made the company choose between him and Steve Jobs. But he’s also a successful investor, mentor and entrepreneur — as well as the person who increased Apple’s sales from $800 million to $8 billion during his decade at the top.

In an interview with Cult of Mac, Sculley, who ran Apple from 1983 to 1993, tells why he doesn’t wear an Apple Watch, makes the case that AAPL stock is undervalued, explains how the Steve Jobs movie twisted facts, and talks about his new book Moonshot and the future of entrepreneurism.

Steve Jobs memorabilia collectors can now grab the holy trifecta of business cards while also doing a bit of good along the way.

Three of Jobs’ business cards from his days at Apple, Pixar and NeXT are up for auction, with proceeds going to The Marin School in California. Bidding started at $600 but it’s already up to $2,405.

Here’s a look at the cards you’ll win if you place the high bid:
