Rare Bill Gates Signed MLB Baseball Appraised at $1,500–$2,000: When Tech Icons Cross into Sports Collectibles

At DJR Authentication, we’ve seen our share of rare and unusual items—from Civil War lithographs to antique Edison motors. But every so often, a submission arrives that stops us in our tracks. That was the case this week with a Major League Baseball signed by Microsoft co-founder Bill Gates, fully authenticated by PSA/DNA.

This isn’t just a collectible—it’s a cultural crossover, combining two of America’s most iconic institutions: baseball and technology.

A Signature That Defies Categories
When most collectors think of autographed baseballs, they think Mantle, Ruth, or Ohtani. But there’s a growing market for signatures from non-baseball icons—especially those who’ve shaped the modern world. Bill Gates is undeniably one of those figures.

This ball, signed clearly in blue ink across the sweet spot, has been authenticated by PSA/DNA, the industry’s leading third-party verifier. It’s a clean, bold autograph from one of the most influential minds in tech history.

Estimated Appraised Value: $1,500–$2,000
While Gates-signed books, photos, and documents occasionally appear at auction, a signed baseball is a true oddity. The rarity of the medium, paired with strong PSA provenance, makes this an eye-catching and valuable crossover piece.

What drives the value:

✓ Signature clarity and placement
✓ PSA/DNA authentication
✓ Unusual medium (MLB ball rather than flat item)
✓ Cultural relevance across multiple collector markets

Collectors of tech memorabilia, modern history, and novelty sports crossovers will find strong appeal in a piece like this.

Why Unusual Autographs Are Growing in Demand
The collectible market has expanded beyond traditional categories. In an age where storytelling drives value, unique combinations like “tech mogul + baseball” become conversation starters—and investment pieces.

More buyers are looking for pieces that reflect personal interests and cultural intersections, not just sports or celebrity fame. This is what makes a Gates-signed baseball so powerful: it tells a story of innovation, influence, and American iconography—all on one ball.
