Era

Circa 2016-2019 (College Career)

Item Type

Baseball

Condition

Excellent/Near Mint. The leather/surface is clean, stitching is vibrant, and ink is bold and sharp.

Rarity

Common for fans of the localized program; not a high-market commodity signature.

Overall Assessment

An authentic piece of Washington State University sports memorabilia from a popular player of the late 2010s. Best suited for an alumni collection.

Authenticity Assessment

Likely authentic based on signature flow and jersey number inscription. Confidence level: 85%.

Signature Style

Abbreviated loop-style signature consisting of a stylized 'T' followed by jersey number '12'. Typical of modern athletes signing under time pressure.

Signature Characteristics

Fast, fluid strokes with light pen pressure. Features a large Initial loop and a smaller trailing loop representing the surname.

Ink & Medium

Blue ballpoint pen on a synthetic or leather baseball surface. High contrast with no significant fading.

Item Description

Standard white baseball with red stitching. Note: While the signer is a football player, 'crossover' signing on different balls (signing a baseball/basketball) is common at fan events.

Estimated Value

$10.00 - $25.00 USD

Comparison to Known Examples

Consistent with team-signed items and fan-day memorabilia from the 2018-2019 Washington State football seasons.

Authentication Tips

Look for the distinctive 'T' loop and the specific placement of the '12'. Verify against WSU team-signed items from the Mike Leach era.

Certification Recommendation

JSA (James Spence Authentication) or PSA/DNA, though the cost of certification may exceed the market value.

Red Flags

No significant red flags; the '12' inscription aligns perfectly with Tinsley's roster number at WSU.

Provenance Notes

Likely obtained at a Washington State University athletic department fan event or 'Cougar Athletic Fund' auction.

Historical Context

Tinsley was a key backup and leadership figure during the highly successful Mike Leach era at Washington State, notably during the 11-win 2018 season.

Market Trends

Stable; value is primarily driven by WSU alumni and local collectors rather than national sports investors.

Investment Potential

Low; primary value is sentimental or for completed team sets for WSU die-hards.

Display & Preservation

Store in a UV-protected acrylic cube and keep away from direct sunlight to prevent the leather from yellowing.

Interesting Facts

Despite being a backup for much of his career, Tinsley was a fan favorite and later transitioned into a coaching role at the collegiate level.
