Item Type

Official MLB baseball

Condition

Very Good condition with minor natural toning on the leather and a clear, legible signature.

Rarity

Moderately scarce in private collections due to the player's selective and historically reluctant signing habits.

Overall Assessment

A classic baseball presentation of a legendary Hall of Famer, warranting professional third-party certification to maximize market value.

Authenticity Assessment

Uncertain - requires professional in-person authentication due to limited visual detail and typical high-end forgery rates for this player.

Signature Style

Clean, distinct full name featuring a stylized 'S' initial followed by 'Koufax' with characteristic loops.

Signature Characteristics

Smooth flow, steady pressure, legible letter forms showing natural speed and minimal tremor.

Ink & Medium

Blue ballpoint pen ink, showing moderate consistency typical of standard writing instruments.

Item Description

Standard stitched leather Major League baseball, housed inside a clear protective display cube with a gold-toned base.

Estimated Value

200 to 500 USD uncertified, potentially higher if certified authentic by a major tier-one authenticator.

Comparison to Known Examples

Appears to follow the baseline structure of known vintage and modern Koufax exemplars, though high-resolution magnification is required.

Authentication Tips

Compare baseline alignment, specific angle of the capital 'S', and natural fluid transitions without pen hesitation.

Certification Recommendation

PSA/DNA or JSA (James Spence Authentication)

Red Flags

No glaring red flags such as shaky strokes or mechanical reproduction are immediately visible from the photograph, but opinion cannot be finalized without physical inspection.

Provenance Notes

Documentation of acquisition origin, direct stadium encounters, or prior auction house receipts greatly impacts trust.

Historical Context

Koufax is celebrated as one of the most dominant left-handed pitchers in baseball history, capturing three Cy Young Awards and four World Series titles.

Market Trends

Demand for vintage Brooklyn/LA Dodgers legends remains consistently robust with steady collector interest.

Investment Potential

Stable to appreciating long-term value given his legendary status and finite supply of genuine signatures.
