Tim Lincecum

Era

Peak fame period - circa 2008-2012

Item Type

Official MLB Baseball (Rawlings)

Condition

Fair/Poor. The ball is heavily soiled with dirt and brownish stains. The Rawlings logo is partially obscured by a smudge. The autograph itself is legible but somewhat affected by the surface wear.

Rarity

Moderate. Lincecum was a prolific signer during his peak, but since retirement, he has become more reclusive, making his autographs consistently desirable.

Overall Assessment

A genuine, 'in-the-wild' example of a Tim Lincecum signature on a well-used baseball. Ideal for a personal collection or a Giants fan, though not a high-end investment piece.

Authenticity Assessment

Likely authentic. The signature matches Lincecum's known 'T-dash' shorthand style frequently used for fans during his playing days, though confidence is tempered by item condition.

Signature Style

Stylized shorthand/monogram. Features a tall vertical 'T' with a detached horizontal bar above, followed by a lowercase 'i' and a rhythmic 'm/y' scrawl. Includes his jersey number '55'.

Signature Characteristics

Spontaneity in the strokes suggests a high-speed signing situation (common for Lincecum). The vertical bar of the 'T' has a slight bottom-heavy pressure point.

Ink & Medium

Blue felt-tip marker (likely Sharpie) on a leather baseball. The ink shows slight bleeding into the grain of the hide, consistent with aging on a non-coated surface.

Item Description

A standard Rawlings red-stitched baseball. The ball appears to be a 'game-used' or 'practice-used' ball rather than a souvenir 'OML' ball, evidenced by significant scuffing and dirt transfer.

Estimated Value

$40 - $75 USD

Comparison to Known Examples

Closely resembles Lincecum's mid-career 'quick' signature. The placement of the '55' is consistent with his habit of tucking it to the right of the 'i'.

Authentication Tips

Look for the detached 'T-bar' which typically floats above the stem. The '55' should be written with a specific speed that shows two quick, slightly open-topped fives.

Certification Recommendation

JSA (James Spence Authentication) or PSA/DNA. JSA is highly respected for Giants-related memorabilia and offers 'Basic Cert' services for common items.

Red Flags

No significant red flags regarding the hand-writing itself; however, the heavy scuffing on the Rawlings logo suggests the ball was signed in a rough environment.

Provenance Notes

Since this is on a scuffed ball, information about which stadium or game it was obtained at would add significant narrative value, though not necessarily monetary value given the condition.

Historical Context

Lincecum, known as 'The Freak,' is one of only two pitchers to win back-to-back Cy Youngs in their first two full seasons. This signature represents the height of 'Lincecum-mania' in the Bay Area.

Market Trends

Stable. Lincecum remains a cult icon in San Francisco. Values for his autographs peak during Giants anniversary celebrations or Hall of Fame ballot discussions.

Investment Potential

Low to Moderate. While Lincecum is a legend, the poor condition of this specific ball limits its upside compared to a clean, official Major League ball.

Similar Autographs

Buster Posey, Matt Cain, Madison Bumgarner (other 2010s Giants core players).

Display & Preservation

Keep in a UV-protected acrylic cube. Do not attempt to clean the dirt off the ball, as this may further smudge the ink or damage the leather grain.

Interesting Facts

Lincecum was notoriously difficult to track down for private signings compared to other stars, but was often generous to fans near the dugout, leading to many 'rough' specimens like this one.
