Condition

Rarity
Common; Griffey is a prolific signer through official channels and hobby shows.
Overall Assessment
A genuine, casual signature from a baseball legend. Ideal for a starter collection or as a placeholder for a more premium signed item like a jersey or 1989 Upper Deck rookie card.
Authenticity Assessment
Likely authentic; the signature exhibits the fluid, shorthand motion characteristic of Griffey's later-life signing style with high confidence in pen flow.

Stylized 'speed' variant; shorthand version of his name typically seen in relaxed or high-volume signing environments.
Signature Characteristics
Consistent upward slant; loop-heavy 'K'; trailing tail on the 'y' that levels off horizontally.

Blue fiber-tip marker (Sharpie-style) on white paper stock.
Item Description
A small rectangular piece of white paper, possibly a cut from a larger sheet or a 3x5 index card.

$40 - $75 USD
Comparison to Known Examples
Matches current 'Standard Shorthand' exemplars used by Griffey for non-premium items (flats/paper).
Authentication Tips
Look for the distinctive 'K' loop that transitions directly into the 'G' swoop; fakes often lack the rapid, effortless speed shown here.
Certification Recommendation
Beckett (BAS) or JSA (James Spence)
Red Flags
No significant red flags; the ink saturation and stroke speed suggest natural hand movement.
Provenance Notes
None provided; requires a COA to reach maximum market value for this specific medium.

Stable; Griffey remains one of the most collected athletes of the 1990s.
