High-velocity strokes, consistent baseline, and a unique circular wrap-around flourish on the lower tail of the H.

Blue ballpoint pen on an official league-style synthetic or leather baseball.

Item Description

White baseball signed on the sweet spot, housed in a plastic cube display case. Adjacent to an Ervin Santana bobblehead.

Estimated Value

$60 - $120 USD (depending on ball brand and presence of JSA/PSA authentication).

Comparison to Known Examples

Matches high-quality 'sweet spot' exemplars provided at Mariners team stores and fan fests.

Authentication Tips

Look for the specific 'loop-back' on the H and the speed of the finishing stroke which typically angles downward.

Certification Recommendation

JSA (James Spence Authentication) or Beckett (BAS) are preferred for modern MLB signatures.

Red Flags

No significant red flags observed; the ink soak is consistent with genuine ballpoint on cowhide.

Provenance Notes

Likely sourced from an in-person stadium signing or a Seattle-area memorabilia show.

Historical Context

Hernandez is the greatest pitcher in Mariners history, known for his 2012 Perfect Game.

Market Trends

Stable; value peaks during his Mariners Hall of Fame ceremonies and recent retirement events.

Investment Potential

Mild; good for a personal collection of pitching greats, but high supply limits massive growth.

Display & Preservation
