Bryce Harper
Two-time NL MVP and 7-time MLB All-Star · Baseball - MLB
Philadelphia Phillies / Washington Nationals

Era
Modern Era - circa 2012-present
Item Type
Baseball
Condition
Excellent/Near Mint. The signature is bold and dark with no visible fading or bleeding. The ball leather appears white with minimal toning.
Rarity
Moderate. While Harper is a prolific signer through paid contracts (Fanatics), authentic street/game signatures are highly sought after.
Overall Assessment
A high-quality, authentic-looking example of a premier modern superstar's autograph. It is highly desirable for both Phillies and Nationals fans.
Authenticity Assessment
Likely authentic; confidence level: High. The signature displays the characteristic lateral speed and loop structure typical of Harper's game-signed or public appearance autographs.
Signature Style
Stylized shorthand script with '34' inscription. It features a sweeping 'B' and a sharp, high-drag 'H' transition that merges into a tail.
Signature Characteristics
Strong initial pressure on the B, a characteristic loop in the 'p' area, and a flat horizontal finish. The '34' is written with a specific bottom-heavy 3 and a sharp 4.
Ink & Medium
Blue permanent marker (likely Sharpie) on a leather baseball.
Item Description
Official League-style baseball, possibly a Rawlings Official Major League Baseball (OMLB), featuring red stitching.
Estimated Value
$250 - $450 USD (higher if authenticated by PSA/DNA or JSA; lower if sold as-is).
Comparison to Known Examples
Matches very well with verified Fanatics-sequentially numbered items and verified in-person examples from his tenure with the Nationals.
Authentication Tips
Look for the distinct '34' (his Washington Nationals number). Check for the 'fluid speed'—forgeries often look shaky or slow, whereas Harper's real signature is very fast and aggressive.
Certification Recommendation
PSA/DNA, JSA (James Spence Authentication), or Beckett Authentication Services (BAS).
Red Flags
No significant red flags observed; the ink soak into the leather is consistent with authentic hide absorption.
Provenance Notes
Since the ball is inscribed '34', it likely dates from his 2012–2018 tenure with the Nationals. Documenting where it was signed (D.C. vs Spring Training) adds value.
Historical Context
Harper was one of the most hyped prospects in baseball history, appearing on Sports Illustrated at age 16. This ball represents the 'prodigy' era of his career.
Market Trends
Stable to Appreciation. As a future Hall of Fame candidate, his early-career '34' signed items remain high-demand staples in the hobby.
Investment Potential
High. Harper's trajectory toward 500 home runs and Cooperstown makes his signed memorabilia a blue-chip investment in the modern sports market.
Similar Autographs
Mike Trout, Shohei Ohtani, Juan Soto, and Aaron Judge.
Display & Preservation
Keep in a UV-protected acrylic cube (like the one shown) and away from direct sunlight or fluorescent lighting to prevent ink fading and leather yellowing.
Interesting Facts
Harper actually changed his jersey number to 3 from 34 when he joined the Phillies out of respect for Roy Halladay, making '34' signed items specific to his early career.
