Item Type
Official Major League Baseball
Condition
Excellent condition overall; the baseball is clean with vibrant red stitching, and the ballpoint signature remains clear and unblemished.
Rarity
Scarce on baseball sweet spots due to his general reluctance to sign baseballs compared to flat items.
Overall Assessment
An appealing baseball featuring a classic Sandy Koufax signature style, though professional third-party authentication is strongly advised before confirming high-end market value.
Authenticity Assessment
Questionable - several concerns noted regarding formation and flow compared to standard authenticated exemplars.
Signature Style
Abbreviated signature style often seen in quick public appearances, featuring distinct looped initials and a trailing flourish, along with the uniform number 32.
Signature Characteristics
The signature shows looping letter formations, a distinct separation between the first and last name initials, and an appended uniform number 32, though the stroke fluidity appears slightly hesitant.
Ink & Medium
Blue ballpoint pen on leather baseball sweet spot.
Item Description
Standard white leather baseball with red stitching, housed in a clear acrylic protective cube.
Estimated Value
100 to 300 USD uncertified / 1000 to 2500 USD if fully authenticated by a top-tier grading service.
Comparison to Known Examples
Genuine Koufax signatures typically exhibit a smooth, flowing rhythm with consistent slant and pressure. This example displays minor signs of hesitation in the loops.
Authentication Tips
Compare closely with known exemplars authenticated by PSA/DNA or JSA, paying specific attention to the fluidity of the capital 'S' and 'K', baseline slope, and pen pressure consistency.
Certification Recommendation
PSA/DNA (Professional Sports Authenticator) or JSA (James Spence Authentication)
Red Flags
Slight stiffness in the flow of the capital letters and unusual baseline alignment relative to verified genuine exemplars.
Provenance Notes
Without direct documentation of the signing event or a reputable letter of provenance, authentication relies strictly on physical exemplar comparison.
