The 10 Most Valuable NBA Autographs

Basketball autographs behave differently from baseball ones. The sport is younger, the stars are fewer, and a handful of names carry almost the whole market.

Here's the order, and more usefully, why each one sits where it does. Price in this category is mostly a supply story.

1. Michael Jordan

Nothing else in basketball is close. Jordan signs under exclusive agreements, has done for decades, and the number of new signed items each year is a business decision rather than a function of demand.

He's also the most forged signature in the sport. His hand changed considerably between his rookie years and now, so the signature style and the item's era have to agree. Anything unauthenticated with his name on it should be assumed fake until a database says otherwise.

2. Kobe Bryant

Bryant's death in 2020 closed the supply permanently, and prices moved immediately and stayed there. He was already selective about signing, so the pool was never large.

This is the clearest example in basketball of the rule that supply beats everything. Nothing about his career changed in 2020. What changed is that no more signatures will ever exist.

3. LeBron James

Under exclusive contract for most of his career, which keeps new supply tight and priced high. He rarely signs for fans at arenas or hotels.

The result is a signature that's genuinely hard to get for a player who's been famous for over twenty years. That scarcity is manufactured rather than accidental, and it works.

4. Bill Russell

Eleven championships in thirteen years, and for much of his life he refused to sign at all. Russell was openly hostile to the autograph business for decades before softening later on, and he died in 2022.

Closed supply plus a long refusal period plus real historical weight puts him higher than casual fans expect.

5. Wilt Chamberlain

Chamberlain died in 1999, before the memorabilia boom of the last twenty years, so far less signed Wilt material exists than for stars who lived into the modern signing era.

A signed Chamberlain item from the 1960s or 1970s is genuinely scarce. The 100-point game is the piece everyone wants and almost nobody has.

6. Kareem Abdul-Jabbar

The league's scoring leader for nearly four decades. Abdul-Jabbar signs, and has sold from his own collection, so supply is healthier than the names above.

That keeps him more affordable than his résumé suggests, which makes him one of the better values on this list if you're buying to own rather than to flip.

7. Magic Johnson

Magic signs regularly and has for years, so his autograph is among the more available from the all-time greats. Value concentrates in Showtime-era items and in pieces that pair him with Larry Bird.

8. Larry Bird

Bird is famously reluctant in public but signs steadily through official channels, so genuine Bird material is available if you want it. We stock signed Bird jerseys on Mitchell & Ness in the $550 to $580 range, which is a reasonable marker for a Hall of Famer who still signs.

Dual-signed Bird and Magic pieces carry a real premium, because the rivalry is the product.

9. Stephen Curry

The most valuable signature among active players. Curry signs under exclusive arrangements, and the market is betting on where his career finishes rather than pricing what he's already done.

Worth knowing: active players carry more risk than retired ones. Supply can still grow for another decade.

10. Shaquille O'Neal

Shaq is everywhere and signs a lot, which caps his prices below where his career would suggest. That's not a knock. It means a collector can own a signed Shaq without a serious budget, and his stylized signature displays beautifully on a basketball.

What actually sets the price

Read back through the list and the pattern is obvious. It isn't rings or scoring titles.

• Whether he's still alive to sign. Kobe, Russell and Chamberlain all sit above where their signing habits alone would put them.
• Whether he's under exclusive contract. Jordan, LeBron and Curry sign planned quantities at set prices.
• Whether he enjoys it. Shaq and Magic sign happily, and their prices reflect that.
• What it's signed on. A signature on a game-model basketball or a Mitchell & Ness jersey is worth more than the same signature on a card.

Before you buy one

Basketball autographs are forged at scale, particularly Jordan and Kobe. Buy certified by PSA/DNA, JSA, Beckett or Fanatics, and look up the serial number in the authenticator's own database rather than trusting a photo of a certificate. Our guide on how to tell if an autograph is real covers the checks you can do yourself, and what a COA guarantees explains what the paperwork does and doesn't promise.

Think about the surface too. A basketball's pebbled texture is one of the harder things to sign cleanly, so placement and pen matter more than on a photo.

We carry signed basketball memorabilia including signed jerseys, all third-party authenticated. For the wider view of which signatures hold value, read the most iconic sports autographs and the rarest signatures in sports.
