Multiple Signers (likely 1983/1984 Oakland Athletics)
Professional Baseball Players and Coaching Staff · Baseball - MLB
Oakland Athletics
Era
Circa 1983-1984
Item Type
Multi-signed Baseball
Condition
Fair/Poor - The ball shows heavy yellowing, toning, and significant fading of the signatures (some are barely visible).
Rarity
Common. Team-signed balls from the early 80s A's are relatively common, especially on non-official balls.
Overall Assessment
A genuine 'era' souvenir featuring players like Mike Warren and Bill Caudill. Due to the condition and fading, its value is primarily sentimental for a fan of the 1980s Oakland Athletics.
Authenticity Assessment
Uncertain - requires professional authentication. While the names match a specific roster, they are faded and share characteristics of a 'souvenir' or 'clubhouse' ball.
Signature Style
Stacked multi-signed format with ballpoint pen; signatures are largely cursive and legible but heavily faded.
Signature Characteristics
Natural variations in slant; Mike Warren (middle-bottom) shows a characteristic loops on the 'M' and 'W'.
Ink & Medium
Blue and black ballpoint pen on a leather-covered baseball. Significant fading due to aging and light exposure.
Item Description
Cushioned Cork Center RO-A baseball. This model was often used for promotional or minor league play, rather than being an Official League Baseball (ONL/OAL).
Estimated Value
$20 - $50 USD
Comparison to Known Examples
The names like Mike Warren and Bill Caudill align with 1984 Oakland roster samples, but the lack of an official league stamp is a concern.
Authentication Tips
Compare Mike Warren's signature to known examples from his 1983 no-hitter period. Check for uniform ink flow to rule out stamps.
Certification Recommendation
JSA (James Spence Authentication) or PSA/DNA as a 'multi-signed' item.
Red Flags
Use of a 'RO-A' non-official baseball often suggests a souvenir/youth product rather than an on-field game ball.
Provenance Notes
Look for records of Oakland home games or spring training attendance during the early 1980s.
Historical Context
Reflects the 'Billyball' era or the immediate aftermath, including Mike Warren who threw a no-hitter in Sept 1983.
Market Trends
Stable. Early 80s Oakland memorabilia has a niche following, but without Hall of Fame names (like Rickey Henderson), value is limited.
Investment Potential
Low. The condition and non-official nature of the ball limit long-term appreciation.
Similar Autographs
1980s Oakland A's Rickey Henderson, Carney Lansford, or Tony Armas.
Display & Preservation
Keep in a UV-protected cube and away from direct light to prevent further fading of the ballpoint ink.
Interesting Facts
Mike Warren's signature is often sought because his career was short, making his autograph harder to find than star players.
