Signature Style

Flowing, stylized signature featuring a large looping 'K' and distinct upward sweep on the 'G', accompanied by 'MVP' and his iconic jersey number '24' (though written neatly as 46/98 or similar inscription format depending on the specific commemorative marker, likely '24' stylized or specific achievement notation).

Estimated Value

$300 - $600 depending on third-party authentication (PSA/JSA/BAS)

Comparison to Known Examples

Matches verified authenticated examples from the late 1990s when his signature was at its most complete and legible before later simplifying into a quicker 'KG' monogram.

Certification Recommendation

PSA/DNA or James Spence Authentication (JSA) are the industry standards for modern baseball stars.

Red Flags

No significant red flags observed; ink flow, placement on the sweet spot, and accompanying inscriptions appear natural and consistent.

Provenance Notes

Direct acquisition stories or original receipts from card shows, team stores, or private signings significantly add to the value and confidence.
